EnglishWhat is the Official MCP Registry?
Updated
The Official MCP Registry at registry.modelcontextprotocol.io is a public directory for discovering Model Context Protocol (MCP) servers. It is built in the open by MCP contributors and serves as a place to browse, search, and find servers rather than a runtime environment where servers are hosted or executed. If you are looking for an MCP server to use, this is where you can start your search.
What the registry provides
The registry is a discovery catalog. Its main purpose is to help you find MCP servers and see what is available. Based on the page, the core features include:
- A server listing — the registry loads and displays servers for browsing.
- Recently Updated — a section highlighting servers that have been updated recently.
- Search — a search function to find specific servers.
- Pagination — Previous and Next controls to move through results.
- A "Show only latest versions" option — a filter to limit results to the newest versions of servers.
Who maintains it
The page states it is "Built in the open by MCP contributors." This indicates the registry is maintained by the MCP community rather than a single closed vendor.
What it is not
The registry is a directory, not a server runtime. It does not appear to host or run MCP servers for you. Its role is to help you discover servers; actually running or connecting to a server happens elsewhere.
Environment options
The page includes a server selector with these options:
| Option | Base URL |
|---|---|
| Production | registry.modelcontextprotocol.io |
| Staging | staging.registry.modelcontextprotocol.io |
| Local | localhost:8080 |
| Custom | (user-provided) |
This suggests the registry exposes an API and has separate production and staging environments, plus a local option for development.
Related resources
The page links to GitHub, Docs, and an API Reference, which are the places to go for source code, documentation, and programmatic access.
When to use it
Use the Official MCP Registry when you want to:
- Discover available MCP servers.
- Check what has been updated recently.
- Search for a specific server by name or function.
- Find the latest version of a server.
It is not the place to run a server or manage your own MCP connections. For those tasks, you would use the server itself or the client that connects to it.
