Today, we're announcing that Azure API Center now supports custom metadata filtering across your entire catalog — including APIs, skills, agents, and MCP tools.
Enterprise API and AI catalogs have expanded dramatically. Where teams once managed dozens of APIs, they now govern hundreds — spanning business units, environments, compliance domains, and an ever-growing roster of AI assets. The catalog itself has become a discovery challenge.
What's new
Developers can now filter catalog assets using organization-defined metadata attributes. These aren't generic tags — they're the classifications your organization already uses: environments, business units, domains, compliance tiers, ownership groups, and more.
Custom metadata filtering works across all major asset types in Azure API Center:
- APIs
- Skills
- Agents
- MCP tools
Why it matters
Discovery friction is a hidden tax on developer productivity. When a developer needs to find the right API for a project, every minute spent navigating inconsistent lists or applying manual filters is a minute not spent building. At scale, this compounds quickly.
Custom metadata filtering addresses this directly by aligning the catalog's search experience with how your organization already thinks about its assets:
- Surface the right assets faster — filter by internal classifications and governance models instead of browsing overwhelming lists
- Improve discoverability at scale — no need to retag or reorganize existing assets to make them findable
- Align with your organizational taxonomy — filter by domain, environment, business unit, compliance requirement, or any custom attribute your teams already use
Built for governed, AI-ready teams
This update reinforces Azure API Center's role as the foundation for scalable, AI-ready discovery experiences — where governance and developer velocity move together, not against each other.
By making enterprise catalogs easier to navigate, Azure API Center helps developers spend less time searching and more time building with governed APIs and AI assets.
