MCP Registry
The official Model Context Protocol Registry is the community catalog/API for discovering MCP servers — the index layer for the MCP ecosystem. An agentic OS can use it (or a private mirror) for discovery while still pinning approved servers in installation config. A community driven registry service for Model Context Protocol (MCP) servers. The MCP registry provides MCP clients with a list of MCP servers, like an app store for MCP servers. 📤 Publish my MCP server | ⚡️ Live API docs | 👀 Ecosystem vision | 📖 Full documentation 2025-10-24 update: The Registry API has entered an API freeze (v0.1) 🎉. For the next month or more, the API will remain stable with no breaking changes, allowing integrators to confidently implement support. This freeze applies to v0.1 while development continues on v0. We'll use this period to validate the API in real-world integrations and.
Why it matters here
In this catalog it is the Agentic Gateways option when you need to front agents and MCP/tool surfaces safely. Keep MCP Registry on the observe/propose side of the loop: useful signals and drafts, with human or policy authority still required before anything irreversible runs.
How it works
Clients connect to the gateway/registry; it authenticates, discovers MCP/agent servers, and proxies tool or agent traffic under configured policy.
- Register or discover the MCP/agent servers the gateway will front.
- Configure authn/z and allow-lists for tools.
- Proxy a tool call from a test agent and verify policy denials.
- Cut agent runtimes over to the gateway endpoint.

When to reach for it
- Use when: The official Model Context Protocol Registry is the community catalog/API for discovering MCP servers — the index layer for the MCP ecosystem matches the bottleneck and you specifically need to front agents and MCP/tool surfaces safely.
- Skip when: another pack already covers the need with less ops surface, or MCP Registry would become a second place people retype truth.
- Prefer instead: compare MCP Gateway Registry, Model Context Protocol before locking the cell.
Limits
- Ops: confirm license, hosting, and release cadence for MCP Registry (modelcontextprotocol/registry) before relying on it in a live corridor.
- Integration: bad credentials, scopes, or schema drift produce empty retrievals or runaway tool/model spend without an obvious UI alarm.
- Scope: Agentic Gateways components support agents; they are not the company ledger or the approval authority.
