An MCP server for Trello boards, powered by Bun for maximum performance.
Connect MCP to Claude, Cursor or any other MCP client and it stops being a tab you switch to. An MCP server for Trello boards, powered by Bun for maximum performance. The mcp mcp server is what makes that connection.
A Model Context Protocol (MCP) server that gives AI agents full access to your Trello boards — cards, lists, checklists, attachments, comments, custom fields, and workspaces — with built-in rate limiting, type safety, and workflow-level tools you won't find in a plain API wrapper, like acceptance-criteria extraction and checklist dependency queries. 57 tools, one npx install, powered by Bun.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Token — Generate using your API keySetup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Configuration is passed through the environment: TRELLO_API_KEY, TRELLO_TOKEN, TRELLO_BOARD_ID, TRELLO_WORKSPACE_ID. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the planning and project tracking options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP's toolset — Token — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.
