MCP reference servers.

This is a short hand-picked list, not a registry — we do not host a browsable or searchable MCP directory, and there is no plan date for one. Every server below is a stdio process, so it runs on Desktop or the CLI, not in the browser. Desktop’s built-in server browser installs each of these by name. To search the full catalogue of community servers, use the official MCP registry.

Bring your own tools.

The official MCP registry lists hundreds of community-contributed servers. We do not mirror, curate, or sign any of them. On the web, the custom connector dialog accepts a remote HTTP or SSE MCP endpoint and your own token; stdio servers like the ones above have no URL, so add those from Desktop or the CLI instead.
