MCP Registry
Official curated registry of MCP servers — discovery, versioning, and metadata for the ecosystem.
The official MCP Registry is a curated catalog of MCP servers with stable URLs, versioning, and metadata. The canonical place to publish or discover a server; clients such as Claude Desktop and Claude Code are expected to consume it programmatically as the registry matures.
What it does
- The official curated MCP registry — discovery, versioning, and metadata for MCP servers
- Community-submitted entries reviewed against spec compliance
- Clients like Claude Desktop and Claude Code are expected to consume it programmatically as it matures
When to use it
Search the registry to discover verified MCP servers and their capabilities instead of trawling GitHub. Also where you submit your own server for discovery.
Getting started
No install — browse the registry web UI. To submit a server, follow the contribution guide in the repository.
Things to know
The registry is young and evolving — coverage is not yet exhaustive, and some entries may trail the latest server releases. Verify a server's own repo before trusting it.
