o3-deep-research is failed with the status incomplete with the reason as content filter
I working on an to do an deep research on internal data. I'm using currently the Azure OpenAI Responses API with MCP Tool. The underlying MCP server deployed into ACA with search and fetch tool with signatures in complaint with the specification (https://developers.openai.com/apps-sdk/build/mcp-server#company-knowledge-compatibility). OpenAI client created with 03-deep-research model with MCP tool, in a loop response status being checked. (https://learn.microsoft.com/en-us/azure/foundry/openai/how-to/deep-research#remote-mcp-server-with-deep-research) Deep Research is being carried out for sometime, I could see in the log that handshake has been made, ListTools invoked, search tool is called post that fetch is called for the queries framed by the model.. But intermittently, the response status is becoming "incomplete" with incomplete reason as "content_filter". Otherwise the deep research is working fine. Not able identify the root cause as there is seems to be no way to identify what caused the content filtration whether its the prompt or completion. How to debug and check the root cause and rectify this ? Or is there known issue with the o3-deep-research model's intermediate reasoning completions Or search and fetch tool results are causing this ? I had uploaded a file made it available to MCP server, the search and fetch tool uses an Azure OpenAI agent to search the data using File Search and fetch tool gets the content of the file based on the id passed. For same file and same research topic the issue is not occurring always but intermittently.GraphRAG and PostgreSQL integration in docker with Cypher query and AI agents (Version 2*)
This is update from previous blog (version 1): GraphRAG and PostgreSQL integration in docker with Cypher query and AI agents | Microsoft Community Hub Review the business needs of this solution from version 1 What's new in version 2? MCP tools for GraphRAG and PostgreSQL with Apache AGE This solution now includes MCP tools for GraphRAG and PostgreSQL. There are five MCP tools exposed: [graphrag_search] Used to run query (local or global) with runtime-tunable API parameters. One important aspect is that query behavior can be tuned at runtime, without changing the underlying index. [age_get_schema_cached] Used for schema inspection and diagnostics. It returns the graph schema (node labels and relationship types) from cache by default; and can optionally refresh the cache by re‑querying the database. This tool is typically used for introspection or debugging, not for answering user questions about data. [age_entity_lookup] Used for quick entity discovery and disambiguation. It performs a simple substring match on entity names or titles and is especially useful for questions like “Who is X?” or as a preliminary step before issuing more complex graph queries. [age_cypher_query] Executes a user‑provided Cypher query directly against the AGE graph. This is intended for advanced users who already know the graph structure and want full control over traversal logic and filters. [age_nl2cypher_query] Bridges natural language and Cypher. This tool converts a natural‑language question into a Cypher query (using only Entity nodes and RELATED_TO edges), executes it, and returns the results. It is most effective for multi‑hop or structurally complex questions where semantic interpretation is needed first, but execution must remain deterministic. Besides that, This solution now uses Microsoft agent framework. It enables clean orchestration over MCP tools, allowing the agent to dynamically select between GraphRAG and graph query capabilities at runtime, with a looser coupling and clearer execution model than traditional Semantic Kernel function plugins. The new Docker image includes graphRAG3.0.5. This version stabilizes the 3.x configuration‑driven, API‑based architecture and improves indexing reliability, making graph construction more predictable and easier to integrate into real workflows. New architecture Updated Step 7 - run query in Jupyter notebook This step runs Jupyter notebook in docker, which is the same as stated in previous blog. > docker compose up query-notebook After clicking the link highlighted in the above screen shot, you can explore all files within the project in the docker, then find the query-notebook.ipynb. https://github.com/Azure-Samples/postgreSQL-graphRAG-docker/blob/main/project_folder/query-notebook.ipynb But in this new version of notebook, the graphRAG3.0.5 uses different library for local Search and global Search. New Step 8 - run agent and MCP tools in Jupyter notebook This step runs Jupyter notebook in docker. > docker compose up mcp-agent Click on the highlighted URL, you can start working on agent-notebook.ipynb. https://github.com/Azure-Samples/postgreSQL-graphRAG-docker/blob/main/project_folder/agent-notebook.... Multiple scenarios of agents with MCP tools are included in the notebook: GraphRAG search: local search and global search examples with direct mcp call. GraphRAG search: local search and global search examples with agent and include mcp tools. Cypher query in direct mcp call. Agent to query in natural language, and mcp tool included to convert NL2Cypher. Agent with unified mcp (all five mcp tools), and based on the question route to the corresponding tool. ['graphrag_search', 'age_get_schema_cached', 'age_cypher_query', 'age_entity_lookup', 'age_nl2cypher_query'] Router agent: selecting the right MCP tool The notebook also includes a router agent that has access to all five MCP tools and decides which one to invoke based on the user’s question. Rather than hard‑coding execution paths, the agent reasons about intent and selects the most appropriate capability at runtime. General routing guidance used in this solution Use [graphrag_search] when the question requires: full dataset understanding, themes, patterns, or trends across documents, exploratory or open‑ended analysis, global understanding or evaluation where we have a corpus of many tokens. In these cases, GraphRAG’s semantic retrieval and aggregation are a better fit than explicit graph traversal. Use AGE‑based tools [age_get_schema_cached, age_entity_lookup, age_cypher_query, age_nl2cypher_query] when the question involves: specific entities or explicit relationships, deterministic graph traversal or filtering, questions that depend on graph structure rather than document semantics, complex graph queries involving multiple entities or multi‑hop paths. Within the AGE toolset: [age_entity_lookup] is typically used for quick entity discovery or disambiguation. [age_cypher_query] is used when a precise Cypher query is already known. [age_nl2cypher_query] is used when the question is expressed in natural language but requires a non‑trivial Cypher query to answer. [age_get_schema_cached] is reserved for schema inspection and diagnostics. The router agent dynamically selects between semantic search and deterministic graph tools based on question intent, keeping retrieval, graph execution, and orchestration clearly separated and extensible. Note: The repository also includes [age_get_schema] and [age_get_schema_details] MCP tools for debugging and development purposes. These are not exposed to agents by default and are superseded by [age_get_schema_cached] for normal use. Key takeaways GraphRAG and postgreSQL AGE querying serve different purposes and each has its advantages. MCP tools provide a uniform interface to both semantic search and deterministic graph operations. Microsoft Agent Framework enables tool‑centric orchestration, where agents select the right capability at runtime instead of hard‑coding logic in prompts. The Jupyter‑based agent workflow makes it easy to experiment with different interaction patterns, from direct tool calls to fully routed agent execution. What's next In this solution, the MCP server and agent runtime are architecturally separated but deployed together in a single Docker container to demonstrate how MCP tools work and to keep local experimentation simple. There are other deployment options, such as running MCP servers remotely, where tools can be hosted and operated independently of the agent runtime. Contributions and enhancements are welcome.Unlocking AI-Driven Data Access: Azure Database for MySQL Support via the Azure MCP Server

Before we delve into these new tools and explore how to get started with them, let’s take a moment to refresh our understanding of MCP and the Azure MCP Server - what they are, how they work, and why they matter. MCP architecture and key components The Model Context Protocol (MCP) is an emerging open protocol designed to integrate AI models with external data sources and services in a scalable, standardized, and secure manner. MCP dictates a client-server architecture with four key components: MCP Host, MCP Client, MCP Server and external data sources, services and APIs that provide the data context required to enhance AI models. To explain briefly, an MCP Host (AI apps and agents) includes an MCP client component that connects to one or more MCP Servers. These servers are lightweight programs that securely interface with external data sources, services and APIs and exposes them to MCP clients in the form of standardized capabilities called tools, resources and prompts.
