Comet Lab Atlas

A registry and hosting platform for discovering and deploying MCP servers.

Smithery is a marketplace and hosting layer for the MCP ecosystem. It indexes thousands of MCP servers, makes them discoverable, and can host and run them so a client connects without local setup.

It is infrastructure for the ecosystem: the place to find an existing MCP server rather than build one.

Where it's ideally used

A fit when you want to find and connect existing MCP servers quickly, without hosting them yourself.

Where it doesn't fit

A directory and host, not a build tool — it does not help you write a custom server.
