Popular MCP servers

MCP servers give an agent tools from outside your repo: your issue tracker, your database, a real browser, current library docs. Every server here was connected with graff before it was listed, and 53 of them add by name with one command.

1 · Add it

graff mcp add linear saves the server to this project's .mcp.json.

2 · Sign in if asked

Hosted servers that use OAuth open a browser sign-in once. Keys go in with --env or --header.

3 · Use it

graff connects and lists the tools right away. A chat that is already open picks the server up on its next request.

Not on the list?

graff mcp add also takes a URL (https://…/mcp), an npm package (@scope/name), a Python package (uvx:name), or a JSON snippet pasted from another client's config. A name that isn't here is looked up in the official MCP registry, and graff only picks a match automatically when its publisher's domain or GitHub account matches the name you typed. The same list is available as /mcp.json.
