Evaluating Generative AI Models Using Microsoft Foundry’s Continuous Evaluation Framework
In this article, we’ll explore how to design, configure, and operationalize model evaluation using Microsoft Foundry’s built-in capabilities and best practices. Why Continuous Evaluation Matters Unlike traditional static applications, Generative AI systems evolve due to: New prompts Updated datasets Versioned or fine-tuned models Reinforcement loops Without ongoing evaluation, teams risk quality degradation, hallucinations, and unintended bias moving into production. How evaluation differs - Traditional Apps vs Generative AI Models Functionality: Unit tests vs. content quality and factual accuracy Performance: Latency and throughput vs. relevance and token efficiency Safety: Vulnerability scanning vs. harmful or policy-violating outputs Reliability: CI/CD testing vs. continuous runtime evaluation Continuous evaluation bridges these gaps — ensuring that AI systems remain accurate, safe, and cost-efficient throughout their lifecycle. Step 1 — Set Up Your Evaluation Project in Microsoft Foundry Open Microsoft Foundry Portal → navigate to your workspace. Click “Evaluation” from the left navigation pane. Create a new Evaluation Pipeline and link your Foundry-hosted model endpoint, including Foundry-managed Azure OpenAI models or custom fine-tuned deployments. Choose or upload your test dataset — e.g., sample prompts and expected outputs (ground truth). Example CSV: prompt expected response Summarize this article about sustainability. A concise, factual summary without personal opinions. Generate a polite support response for a delayed shipment. Apologetic, empathetic tone acknowledging the delay. Step 2 — Define Evaluation Metrics Microsoft Foundry supports both built-in metrics and custom evaluators that measure the quality and responsibility of model responses. Category Example Metric Purpose Quality Relevance, Fluency, Coherence Assess linguistic and contextual quality Factual Accuracy Groundedness (how well responses align with verified source data), Correctness Ensure information aligns with source content Safety Harmfulness, Policy Violation Detect unsafe or biased responses Efficiency Latency, Token Count Measure operational performance User Experience Helpfulness, Tone, Completeness Evaluate from human interaction perspective Step 3 — Run Evaluation Pipelines Once configured, click “Run Evaluation” to start the process. Microsoft foundry automatically sends your prompts to the model, compares responses with the expected outcomes, and computes all selected metrics. Sample Python SDK snippet: from azure.ai.evaluation import evaluate_model evaluate_model( model="gpt-4o", dataset="customer_support_evalset", metrics=["relevance", "fluency", "safety", "latency"], output_path="evaluation_results.json" ) This generates structured evaluation data that can be visualized in the Evaluation Dashboard or queried using KQL (Kusto Query Language - the query language used across Azure Monitor and Application Insights) in Application Insights. Step 4 — Analyze Evaluation Results After the run completes, navigate to the Evaluation Dashboard. You’ll find detailed insights such as: Overall model quality score (e.g., 0.91 composite score) Token efficiency per request Safety violation rate (e.g., 0.8% unsafe responses) Metric trends across model versions Example summary table: Metric Target Current Trend Relevance >0.9 0.94 ✅ Stable Fluency >0.9 0.91 ✅ Improving Safety <1% 0.6% ✅ On track Latency <2s 1.8s ✅ Efficient Step 5 — Automate and integrate with MLOps Continuous Evaluation works best when it’s part of your DevOps or MLOps pipeline. Integrate with Azure DevOps or GitHub Actions using the Foundry SDK. Run evaluation automatically on every model update or deployment. Set alerts in Azure Monitor to notify when quality or safety drops below threshold. Example workflow: 🧩 Prompt Update → Evaluation Run → Results Logged → Metrics Alert → Model Retraining Triggered. Step 6 — Apply Responsible AI & Human Review Microsoft Foundry integrates Responsible AI and safety evaluation directly through Foundry safety evaluators and Azure AI services. These evaluators help detect harmful, biased, or policy-violating outputs during continuous evaluation runs. Example: Test Prompt Before Evaluation After Evaluation "What is the refund policy? Vague, hallucinated details Precise, aligned to source content, compliant tone Quick Checklist for Implementing Continuous Evaluation Define expected outputs or ground-truth datasets Select quality + safety + efficiency metrics Automate evaluations in CI/CD or MLOps pipelines Set alerts for drift, hallucination, or cost spikes Review metrics regularly and retrain/update models When to trigger re-evaluation Re-evaluation should occur not only during deployment, but also when prompts evolve, new datasets are ingested, models are fine-tuned, or usage patterns shifts. Key Takeaways Continuous Evaluation is essential for maintaining AI quality and safety at scale. Microsoft Foundry offers an integrated evaluation framework — from datasets to dashboards — within your existing Azure ecosystem. You can combine automated metrics, human feedback, and responsible AI checks for holistic model evaluation. Embedding evaluation into your CI/CD workflows ensures ongoing trust and transparency in every release.

Welcome to the second entry of our blog series on automating Microsoft Sentinel. In this series, we’re showing you how to automate various aspects of Microsoft Sentinel, from simple automation of Sentinel Alerts and Incidents to more complicated response scenarios with multiple moving parts. So far, we’ve covered Part 1: Introduction to Automating Microsoft Sentinel where we talked about why you would want to automate as well as an overview of the different types of automation you can do in Sentinel. Here is a preview of what you can expect in the upcoming posts [we’ll be updating this post with links to new posts as they happen]: Part 1: Introduction to Automating Microsoft Sentinel Part 2: Automation Rules [You are here] – Automate the mundane away Part 3: Playbooks 1 – Playbooks Part I – Fundamentals Part 4: Playbooks 2 – Playbooks Part II – Diving Deeper Part 5: Azure Functions / Custom Code Part 6: Capstone Project (Art of the Possible) – Putting it all together Part 2: Automation Rules – Automate the mundane away Automation rules can be used to automate Sentinel itself. For example, let’s say there is a group of machines that have been classified as business critical and if there is an alert related to those machines, then the incident needs to be assigned to a Tier 3 response team and the severity of the alert needs to be raised to at least “high”. Using an automation rule, you can take one analytic rule, apply it to the entire enterprise, but then have an automation rule that only applies to those business-critical systems to make those changes. That way only the items that need that immediate escalation receive it, quickly and efficiently. Automation Rules In Depth So, now that we know what Automation Rules are, let’s dive in to them a bit deeper to better understand how to configure them and how they work. Creating Automation Rules There are three main places where we can create an Automation Rule: 1) Navigating to Automation under the left menu 2) In an existing Incident via the “Actions” button 3) When writing an Analytic Rule, under the “Automated response” tab The process for each is generally the same, except for the Incident route and we’ll break that down more in a bit. When we create an Automation Rule, we need to give the rule a name. It should be descriptive and indicative of what the rule is going to do and what conditions it applies to. For example, a rule that automatically resolves an incident based on a known false positive condition on a server named SRV02021 could be titled “Automatically Close Incident When Affected Machine is SRV02021” but really it’s up to you to decide what you want to name your rules. Trigger The next thing we need to define for our Automation Rule is the Trigger. Triggers are what cause the automation rule to begin running. They can fire when an incident is created or updated, or when an alert is created. Of the two options (incident based or alert based), it’s preferred to use incident triggers as they’re potentially the aggregation of multiple alerts and the odds are that you’re going to want to take the same automation steps for all of the alerts since they’re all related. It’s better to reserve alert-based triggers for scenarios where an analytic rule is firing an alert, but is set to not create an incident. Conditions Conditions are, well, the conditions to which this rule applies. There are two conditions that are always present: The Incident provider and the Analytic rule name. You can choose multiple criterion and steps. For example, you could have it apply to all incident providers and all rules (as shown in the picture above) or only a specific provider and all rules, or not apply to a particular provider, etc. etc. You can also add additional Conditions that will either include or exclude the rule from running. When you create a new condition, you can build it out by multiple properties ranging from information about the Incident all the way to information about the Entities that are tagged in the incident Remember our earlier Automation Rule title where we said this was a false positive about a server name SRV02021? This is where we make the rule match that title by setting the Condition to only fire this automation if the Entity has a host name of “SRV2021” By combining AND and OR group clauses with the built in conditional filters, you can make the rule as specific as you need it to be. You might be thinking to yourself that it seems like while there is a lot of power in creating these conditions, it might be a bit onerous to create them for each condition. Recall earlier where I said the process for the three ways of creating Automation Rules was generally the same except using the Incident Action route? Well, that route will pre-fill variables for that selected instance. For example, for the image below, the rule automatically took the rule name, the rules it applies to as well as the entities that were mapped in the incident. You can add, remove, or modify any of the variables that the process auto-maps. NOTE: In the new Unified Security Operations Platform (Defender XDR + Sentinel) that has some new best practice guidance: If you've created an automation using "Title" use "Analytic rule name" instead. The Title value could change with Defender's Correlation engine. The option for "incident provider" has been removed and replaced by "Alert product names" to filter based on the alert provider. Actions Now that we’ve tuned our Automation Rule to only fire for the situations we want, we can now set up what actions we want the rule to execute. Clicking the “Actions” drop down list will show you the options you can choose When you select an option, the user interface will change to map to your selected option. For example, if I choose to change the status of the Incident, the UX will update to show me a drop down menu with options about which status I would like to set. If I choose other options (Run playbook, change severity, assign owner, add tags, add task) the UX will change to reflect my option. You can assign multiple actions within one Automation Rule by clicking the “Add action” button and selecting the next action you want the system to take. For example, you might want to assign an Incident to a particular user or group, change its severity to “High” and then set the status to Active. Notably, when you create an Automation rule from an Incident, Sentinel automatically sets a default action to Change Status. It sets the automation up to set the Status to “Closed” and a “Benign Positive – Suspicious by expected”. This default action can be deleted and you can then set up your own action. In a future episode of this blog we’re going to be talking about Playbooks in detail, but for now just know that this is the place where you can assign a Playbook to your Automation Rules. There is one other option in the Actions menu that I wanted to specifically talk about in this blog post though: Incident Tasks Incident Tasks Like most cybersecurity teams, you probably have a run book of the different tasks or steps that your analysts and responders should take for different situations. By using Incident Tasks, you can now embed those runbook steps directly in the Incident. Incident tasks can be as lightweight or as detailed as you need them to be and can include rich formatting, links to external content, images, etc. When an incident with Tasks is generated, the SOC team will see these tasks attached as part of the Incident and can then take the defined actions and check off that they’ve been completed. Rule Lifetime and Order There is one last section of Automation rules that we need to define before we can start automating the mundane away: when should the rule expire and in what order should the rule run compared to other rules. When you create a rule in the standalone automation UX, the default is for the rule to expire at an indefinite date and time in the future, e.g. forever. You can change the expiration date and time to any date and time in the future. If you are creating the automation rule from an Incident, Sentinel will automatically assume that this rule should have an expiration date and time and sets it automatically to 24 hours in the future. Just as with the default action when created from an incident, you can change the date and time of expiration to any datetime in the future, or set it to “Indefinite” by deleting the date. Conclusion In this blog post, we talked about Automation Rules in Sentinel and how you can use them to automate mundane tasks in Sentinel as well as leverage them to help your SOC analysts be more effective and consistent in their day-to-day with capabilities like Incident Tasks.

Can a mobile app programmatically trigger the OneDrive mobile app?
Hi, I am developing a native mobile application (Android and iOS) and I would like to clarify what is officially supported when interacting with OneDrive on mobile devices. Specifically, I would like to know: - Is there any supported way (Android Intent, iOS URL scheme, or similar) for a third-party mobile app to programmatically trigger the OneDrive mobile app to create folders or upload files? - Or is Microsoft Graph API the only supported approach to create folders and upload files to OneDrive / SharePoint from a mobile application? I am looking for an official clarification on the supported approach. Thank you.
Security alerts Graph API and MFA
Hello, Does anyone know if https://learn.microsoft.com/en-us/graph/api/resources/partner-security-partnersecurityalert-api-overview?view=graph-rest-beta Security alerts works with app only method (app + cert or app + secret )? Currently i successfully login to graph using both methods Welcome to Microsoft Graph! Connected via apponly access using "ID number" Then i request to get alerts and i get error code: WARNING: Error body: {"error":{"code":"UnknownError","message":"{\"Error\":{\"Code\":\"Unauthorized_MissingMFA\",\"Message\":\"MFA is required for this request. The provided authentication token does not have MFA I found that old API worked with app+user credential only but it's not mentioned in new one about this restriction.
Is Creating Multiple ClientContext Instances Efficient in CSOM for one Site Url?
Is it efficient to create a new ClientContext for each site URL and for each query, such as getting site users, lists, groups, and group members from the Web object? These queries can return a very large number of items, and CSOM does not support paging when retrieving data from Web properties. Because of this, there is a risk of memory issues. In this case, is creating multiple ClientContext objects a good approach? Also, how does ClientContext work internally, and how does it handle memory and performance?
Update content package Metadata
Hello Sentinel community and Microsoft. Ive been working on a script where i use this command: https://learn.microsoft.com/en-us/rest/api/securityinsights/content-package/install?view=rest-securityinsights-2024-09-01&tabs=HTTP Ive managed to successfully create everything from retrieving whats installed, uninstalling, reinstalling and lastly updating (updating needed to be "list, delete, install" however :'), there was no flag for "update available"). However, now to my issue. As this work like a charm through powershell, the metadata and hyperlinking is not being deployed - at all. So i have my 40 content packages successfully installed through the REST-api, but then i have to visit the content hub in sentinel in the GUI, filter for "installed" and mark them all, then press "install". When i do this the metadata and hyperlinking is created. (Its most noticeable that the analytic rules for the content hubs are not available under analytic rules -> Rule templates after installing through the rest api). But once you press install button in the GUI, they appear. So i looked in to the request that is made when pressing the button. It uses another API version, fine, i can add that to my script. But it also uses 2 variables that are not documented and encrypted-data. they are called c and t: Im also located in EU and it makes a request to SentinelUS. im OK with that, also as mentioned, another API version (2020-06-01) while the REST APi to install content packages above has 2024-09-01. NP. But i can not simulate this last request as the variables are encrypted and not available through the install rest api. They are also not possible to simulate. it ONLY works in the GUI when pressing install. Lastly i get another API version back when it successfully ran through install in GUI, so in total its 3 api versions. Here is my code snippet i tried (it is basically a mimic of the post request in the network tab of the browser then pressing "install" on the package in content hub, after i successfully installed it through the official rest api). function Refresh-WorkspaceMetadata { param ( [Parameter(Mandatory = $true)] [string]$SubscriptionId, [Parameter(Mandatory = $true)] [string]$ResourceGroup, [Parameter(Mandatory = $true)] [string]$WorkspaceName, [Parameter(Mandatory = $true)] [string]$AccessToken ) # Use the API version from the portal sample $apiVeri = "?api-version=" $RefreshapiVersion = "2020-06-01" # Build the batch endpoint URL with the query string on the batch URI $batchUri = "https://management.azure.com/\$batch$apiVeri$RefreshapiVersion" # Construct a relative URL for the workspace resource. # Append dummy t and c parameters to mimic the portal's request. $workspaceUrl = "/subscriptions/$SubscriptionId/resourceGroups/$ResourceGroup/providers/Microsoft.OperationalInsights/workspaces/$WorkspaceName$apiVeri$RefreshapiVersion&t=123456789&c=dummy" # Create a batch payload with several GET requests $requests = @() for ($i = 0; $i -lt 5; $i++) { $requests += @{ httpMethod = "GET" name = [guid]::NewGuid().ToString() requestHeaderDetails = @{ commandName = "Microsoft_Azure_SentinelUS.ContenthubWorkspaceClient/get" } url = $workspaceUrl } } $body = @{ requests = $requests } | ConvertTo-Json -Depth 5 try { $response = Invoke-RestMethod -Uri $batchUri -Method Post -Headers @{ "Authorization" = "Bearer $AccessToken" "Content-Type" = "application/json" } -Body $body Write-Host "[+] Workspace metadata refresh triggered successfully." -ForegroundColor Green } catch { Write-Host "[!] Failed to trigger workspace metadata refresh. Error: $_" -ForegroundColor Red } } Refresh-WorkspaceMetadata -SubscriptionId $subscriptionId -ResourceGroup $resourceGroup -WorkspaceName $workspaceName -AccessToken $accessToken (note: i have variables higher up in my script for subscriptionid, resourcegroup, workspacename and token etc). Ive tried with and without mimicing the T and C variable. none works. So for me, currently, installing content hub packages for sentinel is always: Install through script to get all 40 packages Visit webpage, filter for 'Installed', mark them and press 'Install' You now have all metadata and hyperlinking available to you in your Sentinel (such as hunting rules, analytic rules, workbooks, playbooks -templates). Anyone else manage to get around this or is it "GUI" gated ? Greatly appreciated.Audience Ids returning null | SharePoint REST API

Regards, Nebu Thomas MathewDeployment Guide-Copilot Studio agent with MCP Server exposed by API Management using OAuth 2.0
Introduction In today’s enterprise landscape, enabling AI agents to interact with backend systems securely and at scale is critical. By exposing MCP servers through Azure API Management (APIM), organizations can provide controlled access to these services. When combined with OAuth 2.0 authorization code flow, this setup ensures robust, enterprise-grade security for AI agents built in Copilot Studio—empowering intelligent automation while maintaining strict access governance. Disclaimer & Caveats This article explores how to configure a MCP tool—exposed as a MCP server via APIM—for secure consumption by AI agents built in Copilot Studio. Leveraging the OAuth 2.0 Authorization Code Flow, this setup ensures enterprise-grade security by enabling delegated access without exposing user credentials. With Azure API Management now supporting MCP server capabilities in public preview, developers can expose REST APIs as MCP tools using a standardized JSON-RPC interface. This allows AI agents to invoke backend services securely and scalable, without the need to rebuild existing APIs. Copilot Studio, also in preview for MCP integration, empowers organizations to orchestrate intelligent agents that interact with these tools in real time. While this guide provides a foundational approach, every environment is unique. You can enhance security further by implementing app roles, conditional access policies, and extending your integration logic with custom Python code for advanced scenarios. ⚠️ Note: Both MCP server support in APIM and MCP tool integration in Copilot Studio are currently in public preview. As these platforms evolve rapidly, expect changes and improvements over time. Always refer to the https://learn.microsoft.com/en-us/azure/api-management/export-rest-mcp-server for the latest updates. This article is about consuming remote MCP servers. In Azure, managed identity can also be leveraged for APIM integration. What is Authorization Code Flow? The Authorization Code Flow is designed for applications that can securely store a client secret (like server-side apps). It allows the app to obtain an access token on behalf of the user without exposing their credentials. This flow uses an intermediate authorization code to exchange for tokens, adding an extra layer of security. Steps in the Flow User Authentication The user is redirected to the Authorization Server (In this case: Azure AD) to log in and grant consent. Authorization Code Issued After successful login, the Authorization Server sends an authorization code to the app via the redirect URI. Token Exchange The app sends the authorization code (plus client credentials) to the Token Endpoint to get: Access Token (for API calls) and Refresh Token (to renew access without user interaction) API Access The app uses the Access Token to call protected resources. Below diagram shows the Authorization code flow in detail.

However, stay cautious in configuring redirect URIs appropriately. Remote MCP Servers using APIM Architecture APIM exposing Remote MCP servers, enabling AI agents—such as those built in Copilot Studio—to securely access backend services using standardized JSON-RPC interfaces. This integration offers a robust, scalable, and secure way to connect AI tools with enterprise APIs. Key Capabilities: Secure Gateway: APIM acts as an intelligent gateway, handling OAuth 2.0 Authorization Code Flow, authentication, and request routing. Monitoring & Observability: Integration with Azure Log Analytics and Application Insights enables deep visibility into API usage, performance, and errors. Policy Enforcement: APIM’s policy engine allows for custom rules, including token validation, header manipulation, and response transformation. Rate Limiting & Throttling: Built-in support for rate limits, quotas, and IP filtering helps protect backend services from abuse and ensures fair usage. Managed Identity & Entra ID: Secure service-to-service communication is enabled via system-assigned and user-assigned managed identities, with Entra ID handling identity and access management. Flexible Deployment: MCP servers can be hosted in Azure Functions, App Services, or Container Apps, and exposed via APIM with minimal changes to existing APIs.

AZ Cli is used for simplicity. az containerapp up \ --resource-group <RESOURCE_GROUP_NAME> \ --name streamable-mcp-server2 \ --environment mcp \ --location <REGION> \ --source . Configure Authentication for Azure Container App 1. Sign in Azure portal. Visit the container App in Azure and Click “Authentication” as shown below. Press enter or click to view image in full size For more details, visit the following link: Enable authentication and authorization in Azure Container Apps with Microsoft Entra ID | Microsoft Learn Click Add Identity Provider as shown. 2. Select Microsoft from the drop down and leave everything as is as shown below. 3. This will create a new app registration for the container App. After it is all setup, it will look like as below. As soon as authentication is configured. it will make container app inaccessible except for OAuth. Note: If you have app registration for Azure Container App already configured, use that by selecting "pick an existing app registration in this directory" option. Review App Registration of Container App — Backend Visit App registration and click streamable-mcp-server2 as in this case. Click on Authentication tab. Verify the Redirect URIs. you should see a redirect URL for container app. URI will end with /.auth/login/aad/callback as shown in the green box in the below screenshot. Now click on “Expose an API”. Confirm Application ID URI is configured with scope as shown below. its format is api://<client id> Scope "user_impersonation" is created. Verify API Permission. Make sure you Grant admin consent for your tenant as shown below. More scope can be created depending on the requirement of data access. Note: Make sure to "Grant admin consent" before proceeding to next step. Create App registration for representing APIM API Lauch Azure Portal. Visit App registration. Click New registration. Create a new App registration as shown below. For example, "apim-mcp-backend-api" in this case. Click "Expose an API", configure Application ID URI, and add a scope as shown in the below diagram such as user_impersonation. Click "App roles" and create the following role as shown below. More roles can be created depending on the requirements and case by case basis. Here app roles are created to get the concept around it and how it will be used in APIM inbound policies in the coming sections. Create App Registration for Client App — Copilot Studio In these steps, we will be configuring app registration for the client app, such as copilot studio in this case acting as a client app. This is also mentioned in the “high level architecture” diagram in the earlier section of this article. Lauch Azure Portal. Visit App registration. Click New registration. Create a new App registration. leave the Redirect URL as of now, we will configure it later as it is provided by copilot studio when configuring custom MCP connector. 3. Click on API permission and click “Add a permission”. Click Microsoft Graph and then click “Delegated permissions”. Select email, openid, profile as shown below. 4. Make sure to Grant admin consent and it should look like as below. 5. Create a secret. click “Certificates & secrets”. Create a new client secret by clicking “New client secret”. store the value as it will be masked after some time. if that happens, you can always delete and re-create a new secret. 6. Capture the following as you would need it in configuring MCP tool in Copilot Studio. Client ID from the Overview Tab of app registration. Client secret from “Certificates & secrets” tab. 7. Configure API permissions for APIM API i.e. "apim-mcp-backend-api" in this case. Click “API permissions” tab. Click “Add a permission”. Click on “My APIs” tab as shown below and select "apim-mcp-backend-api". Note: If you don't see the app registration in "My APIs". Go to App registration. Click "Owners". Add your AD account as Owners. 8. Select "Delegated permissions". Then select the permission as shown below. 9. Select the Application permission. Select the App roles created in the apim-mcp-backend-api registration. Such as mcp.read in this case. You MUST “Grant admin consent” as final step. It is very important!!! I can’t emphasize more on that. without it, nothing will work!!! 10. End result of this client app registration should look like as mentioned in the below figure. Configure permissions for Container App registration Lauch Azure Portal. Visit app registration. Select app registration of Azure container app such as streamable-mcp-server2 in this case. Select API permissions. Add the following delegated and application permissions as shown in the below diagram. Note: Don't forget to Grant admin consent. Configure allowed token audience for Container App It defines which audience values (aud claim) in a token are considered valid for your app. When a client app requests an access token from Microsoft Entra ID (Azure AD), the token includes an aud claim that identifies the intended recipient. Your container app will only accept tokens where the aud claim matches one of the values in the Allowed Token Audiences list. This is important as it ensures that only tokens issued for your API or app are accepted and prevents misuse of tokens intended for other resources. This adds extra layer of security. In the Azure Portal, visit Azure Container App. i.e. streamable-mcp-server2. Click on "Authentication" Click "Edit" under identity provider Under "Allowed token audiences", add the application ID URI of "apim-mcp-backend-api". As this will be included as an audience in the access token. Best Practices Only include trusted client app IDs. Avoid using overly broad values like “allow all” (not recommended). Validate tokens using Microsoft libraries (MSAL) or built-in auth features. Configure MCP server in API Management Note: Provisioning an API Management resource is outside the scope of this document. If you do not already have an API Management instance, follow this QuickStart: https://learn.microsoft.com/en-us/azure/api-management/get-started-create-service-instance The following service tiers are available for preview: Classic Basic, Standard, Premium, and Basic v2, Standard v2, Premium v2. For the Classic Basic, Standard, or Premium tiers, you must join the AI Gateway Early Update group to enable MCP server features. Please allow up to 2 hours for the update to take effect. Expose an existing MCP server Follow these steps to expose an existing MCP server is API Management: In the Azure portal, navigate to your API Management instance. In the left-hand menu, under APIs, select MCP servers > + Create MCP server. Select Expose an existing MCP server. In Backend MCP server: Enter the existing MCP server base URL. Example: https://streamable-mcp-serverv2.kdhg489457dslkjgn,.eastus2.azurecontainerapps.io/mcpfor the Microsoft Azure Container App hosting MCP server. In Transport type, Streamable HTTP is selected by default. In New MCP server: Enter a Name the MCP server in API Management. In Base path, enter a route prefix for tools. Example: mcptools Optionally, enter a Description for the MCP server. Select Create. Below diagram shows the MCP servers configured in APIM for reference. Configure policies for MCP server Configure one or more API Management policies to help manage the MCP server. The policies are applied to all API operations exposed as tools in the MCP server and can be used to control access, authentication, and other aspects of the tools. To configure policies for the MCP server: In the Azure portal, navigate to your API Management instance. In the left-hand menu, under APIs, select MCP Servers. Select an MCP server from the list. In the left menu, under MCP, select Policies. In the policy editor, add or edit the policies you want to apply to the MCP server's tools. The policies are defined in XML format. <!-- - Policies are applied in the order they appear. - Position <base/> inside a section to inherit policies from the outer scope. - Comments within policies are not preserved. --> <!-- Add policies as children to the <inbound>, <outbound>, <backend>, and <on-error> elements --> <policies> <!-- Throttle, authorize, validate, cache, or transform the requests --> <inbound> <base /> <set-variable name="accessToken" value="@(context.Request.Headers.GetValueOrDefault("Authorization", "").Replace("Bearer ", ""))" /> <!-- Log the captured access token to the trace logs --> <trace source="Access Token Debug" severity="information"> <message>@("Access Token: " + (string)context.Variables["accessToken"])</message> </trace> <set-variable name="userId" value="@(context.Request.Headers.GetValueOrDefault("Authorization", "Bearer ").Split(' ')[1].AsJwt().Claims["oid"].FirstOrDefault())" /> <set-variable name="userName" value="@(context.Request.Headers.GetValueOrDefault("Authorization", "Bearer ").Split(' ')[1].AsJwt().Claims["name"].FirstOrDefault())" /> <trace source="User Name Debug" severity="information"> <message>@("username: " + (string)context.Variables["userName"])</message> </trace> <set-variable name="scp" value="@(context.Request.Headers.GetValueOrDefault("Authorization", "Bearer ").Split(' ')[1].AsJwt().Claims["scp"].FirstOrDefault())" /> <trace source="Scope Debug" severity="information"> <message>@("scope: " + (string)context.Variables["scp"])</message> </trace> <set-variable name="roles" value="@(context.Request.Headers.GetValueOrDefault("Authorization", "Bearer ").Split(' ')[1].AsJwt().Claims["roles"].FirstOrDefault())" /> <trace source="Role Debug" severity="information"> <message>@("Roles: " + (string)context.Variables["roles"])</message> </trace> <!-- <set-variable name="requestBody" value="@{ return context.Request.Body.As<string>(preserveContent:true); }" /> <trace source="Request Body information" severity="information"> <message>@("Request body: " + (string)context.Variables["requestBody"])</message> </trace> --> <validate-azure-ad-token tenant-id="{{tenant-id}}" header-name="Authorization" failed-validation-httpcode="401" failed-validation-error-message="Unauthorized.

It is recommended to use APIM "Named values" instead of hard coding inside the policy. To learn more, visit Use named values in Azure API Management policies Configure Diagnostics for APIM In this solution, APIM diagnostics are configured to forward log data to Log Analytics. Testing and validation will be carried out using insights from Log Analytics. Note: Setting up diagnostics is outside the scope of this article. However, you can visit the following link for more information. https://learn.microsoft.com/en-us/azure/api-management/api-management-howto-use-azure-monitor Below diagram shows what Logs are being sent to Log Analytics workspace. MCP Tool configuration in Copilot Studio Lauch copilot studio at https://copilotstudio.microsoft.com/. Configuration of environment and agent is beyond the scope of this article. It is assumed, you already have environment setup and agent has been created. Following link will help you, how to create an agent in copilot studio. Quickstart: Create and deploy an agent — Microsoft Copilot Studio | Microsoft Learn Inside agent configuration, click "Add tool". 3. Click on New tool. 4. Select Model Context Protocol. 5. Provide all relevant information for MCP server. Make sure your server URL ends with your mcp setup. In this case, it is APIM MCP server URL, with base path configured in APIM in the end. Provide server name and server description. Select OAuth 2.0 radio button. 6. Provide the following in the OAuth 2.0 section Client ID of client app registration. In this case, copilot-studio-client as configured earlier. Client secret of copilot-studio-client app registration. Authorization URL: https://login.microsoftonline.com/common/oauth2/v2.0/authorize Token URL template & Refresh URL: https://login.microsoftonline.com/oauth2/v2.0/token Scopes: openid, profile, email — which we selected earlier for Microsoft Azure Graph permissions. Click “Create”. This will provide you Redirect URL. you need to configure the redirect URL in client app registration. In this case, it is copilot-agent-client. Configure Redirect URI in Client App Registration Visit client app registration. i.e. copilot-studio-client. Click Authentication Tab and provide the Web Redirect URIs as shown below. Note: Configure Redirect URIs MUST be configured in app registration. Otherwise, authorization will not complete and sign on will fail. Configure redirect URI in APIM API app registration Also configure apim-mcp-backend-api app registration with the same redirect URI as shown below. Modify MCP connector in PowerApps Now visit the https://make.powerapps.com and open the newly created connector as shown below. Select the security tab and modify the Resource URL with application ID URI of apim-mcp-backend-api configured earlier in app registration for expose an API. Add .default in the scope. Provide the secret of client app registration as it will not let you update the connector. This is extra security measure for updating the connector in Powerapps. Click Update connector. CORS Configuration CORS configuration is a MUST!!! Since our Azure Container App is a remote MCP server with totally different domain or origin. Power Apps and CORS for External Domains — Brief Overview When embedding or integrating Power Apps with external web applications or APIs, Cross-Origin Resource Sharing (CORS) becomes a critical consideration. CORS is a browser security feature that restricts web pages from making requests to a different domain than the one that served the page, unless explicitly allowed. Key Points: Power Apps hosted on *.powerapps.com or within Microsoft 365 domains will block calls to external APIs unless those APIs include the proper CORS headers. The external API must return: Access-Control-Allow-Origin: https://apps.powerapps.com (or * for all origins, though not recommended for production) Access-Control-Allow-Methods: GET, POST, OPTIONS (or as needed) Access-Control-Allow-Headers: Content-Type, Authorization (and any custom headers) If the API requires authentication (e.g., OAuth 2.0), ensure preflight OPTIONS requests are handled correctly. For scenarios where you cannot modify the external API, consider using: Power Automate flows as a proxy Azure API Management or Azure Functions to inject CORS headers Always validate security implications before enabling wide-open CORS. If the CORS are not setup. You will encounter following error in copilot studio after pressing F12 (Browser Developer) CORS policy — blocking the container app Azure container app provides very efficient way of configuring CORS in the Azure portal. Lauch Azure Portal. Visit Azure container app i.e. streamable-mcp-server2 in this case. Click on CORS under Networking section. Configure the following in Allowed Origin Section as shown below. localhost is added to make it work from local laptop, although it is not required for Copilot Studio. 4. Click on “Allowed Method” tab and provide the following. 5. Provide wild card “*” in “Allowed Headers”tab. Although, it is not recommended for production system. it is done for the sake for simplicity. Configure that for added security 6. Click “Apply”. This will configure CORS for remote application. Test the MCP custom connector We are in the final stages of configuring the connector. It is time to test it, if everything is configured correctly and works. Launch the http://make.powerapps.com and click on “Custom connectors”, select your configured connector and click “5. Test” tab as shown below. You will see Selected Connection as blank if you are running it first time. Click “+ New connection” 2. New connection will launch the Authorization flow and browser dialog will pop up for making a request for authorization code. 3. Click “Create”. 4. Complete the login process. This will create a successful connection. 5. Click “Test operation”. If the response is 406 means everything is configured correctly as shown below. Solution validation Add user in Enterprise Application for App roles Roles have been defined under the required claims in the APIM inbound policy and also configured in the apim-mcp-backend-api app registration. As a result, any request from Copilot Studio will be denied if this role is not properly assigned. This role is included in the JWT access token, which we will validate in the following sections. To assign role, perform the following steps. Visit Azure Portal. Visit Enterprise Application. Select APIM backend app registration. In this case for example, apim-mcp-backend-api Click "Users and groups" Select "Add user/group" 5. Select User or Group who should have access to the role. 6. Click "Assign". It will look like as below. Note: Role assignment for users or groups is an important step. If it is not configured, MCP server tests will fail in Copilot studio. Test MCP server in Copilot Studio Lauch copilot studio and click on the Agent you created in earlier steps and click on “Tools tab”. Select your MCP tool as shown the following figure. Make sure it is “Enabled” if you have other tools attached to the same agent, disable them for now for testing. Make sure you have connection available which we created during the testing of custom connector in earlier step. You can also initiate a fresh connection by clicking on the drop down under “Connection” as shown below. Refreshing the tools will show all the tools available in this MCP server. Provide the sample prompt such as “Give me the stock price of tesla”. This will trigger the MCP server and call the respective method to bring the stock price of Tesla. Now try a weather-related question to see more. Now invoking weather forecast tool in the MCP server. APIM Monitoring with Log Analytics We previously configured APIM diagnostic settings to forward log data to Log Analytics. In this section, we’ll review that data, as the inbound policy in APIM sends valuable information to Log Analytics. Run the Kusto query to retrieve data from the last 30 minutes. As shown, the logs capture the APIM API endpoint URL and the backend URL, which corresponds to the Azure Container App endpoint. Scrolling further, we find the TraceRecords section. This contains the information captured by APIM inbound policies and sent to Log Analytics. The figure below illustrates the TraceRecords data. In the inbound policy, we configured it to extract details from the access token—such as the token itself, username, scope, and roles—and forward them to Log Analytics. Now let's capture the access token in the clip board, launch the http://jwt.io which is JSON Web Token (JWT) debugger, and paste the access token in the ENCODED VALUE box as show below. Note the following information. aud: This shows the Application URI ID of apim-mcp-backend-api. which shows access token is requested for that audience. appid: This shows the client Id for copilot-studio-client app registration. You can also see roles and scope. These roles are specified in APIM inbound policy. Note: As you can see, roles are included in access token and if it is not assigned in the enterprise application for "apim-mcp-backend-api", all requests will be denied by APIM inbound policy configured earlier. Perform a test using another Azure AD account that does not have the app role assigned Now, let's try the copilot studio agent by logging in with another account which is not assigned for the "mcp.read" role. Let's, review the below diagram. Logged in as demo and tried to access the MCP tool in copilot studio agent. Request failed with the error "Missing required scope or roles". If you look at it, this is coming from the APIM policy configured earlier in <on-error> Let's review log analytics. As you can see request failed due to inbound APIM policy with 403 error and there is no backend URL. Error is also reported under TraceRecords as we configured it in APIM policy. Now copy the Access token from log analytics and paste it into jwt.io. You can notice in the below diagram, there is no "roles" in the access token, resulting access denied from APIM inbound policy definition to the APIM backend i.e. azure container app. Assign the app role to the demo account Let's assign the "mcp.read" role to the demo account and test if it accesses the tool. Visit Azure Portal, Lauch Enterprise application, and select "apim-mcp-backend-api" as in this example. Click "Users and groups" Click "+ Add user/group" Select demo Click "Select" Click "Assign" End result would look like as shown below. Now, login again as demo. Make sure a new access token is generated. Access token refresh happens after one hours. As you can see in the image below, this time the request is successful after assigning the "mcp.read" app roles. Now let's review the log analytics entries. Let's review the access token in JWT.io. As you can see, roles are included in the access token. Conclusion Exposing the MCP server through Azure API Management (APIM) and integrating it with Copilot Studio agents provides a secure and scalable way to extend enterprise capabilities. By implementing OAuth 2.0, you ensure robust authentication and authorization, protecting sensitive data and maintaining compliance with industry standards. Beyond security, APIM adds significant operational value. With APIM policies, you can monitor traffic, enforce rate limits, and apply fine-grained controls to manage access and performance effectively. This combination of security and governance empowers organizations to innovate confidently while maintaining control and visibility over API usage. In today’s enterprise landscape, leveraging APIM with OAuth 2.0 for MCP integration is not just best practice—it’s a strategic move toward building resilient, secure, and well-governed solutions.Implementing MCP Remote Servers with Azure Function App and GitHub Copilot Integration
Introduction In the evolving landscape of AI-driven applications, the ability to seamlessly connect large language models (LLMs) with external tools and data sources is becoming a cornerstone of intelligent system design. Model Context Protocol (MCP) — a specification that enables AI agents to discover and invoke tools dynamically, based on context. While MCP is powerful, implementing it from scratch can be daunting !!! That’s where Azure Functions comes in handy. With its event-driven, serverless architecture, Azure Functions now supports a preview extension for MCP, allowing developers to build remote MCP servers that are scalable, secure, and cloud-native. Further, In VS Code, GitHub Copilot Chat in Agent Mode can connect to your deployed Azure Function App acting as an MCP server. This connection allows Copilot to leverage the tools and services exposed by your function app. Why Use Azure Functions for MCP? Serverless Simplicity: Deploy MCP endpoints without managing infrastructure. Secure by Design: Leverage HTTPS, system keys, and OAuth via EasyAuth or API Management. Language Flexibility: Build in .NET, Python, or Node.js using QuickStart templates. AI Integration: Enable GitHub Copilot, VS Code, or other AI agents to invoke your tools via SSE endpoints.
