What is the MCP Server?

An MCP server for Trello boards, powered by Bun for maximum performance.

What the server does

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.

  • Acceptance criteria, natively — get_acceptance_criteria pulls a card's AC checklist straight into your agent's context — no competitor offers it
  • Watch anything — watch_card and watch_list route card and list activity into your Trello notifications
  • Full list management — create, update, reorder (update_list_position), and archive lists
  • Board and workspace switching on the fly — no restarts, no config edits
  • Rate limiting handled for you — respects Trello's API limits automatically (300 req/10s per key, 100 req/10s per token)
  • Bun-powered — fast startup and a 2.8-4.4x performance boost over the old Node build. npx and npm work too
