MCP Server Trello

<a href="https://glama.ai/mcp/servers/klqkamy7wt"><img width="380" height="200" src="https://glama.ai/mcp/servers/klqkamy7wt/badge" alt="Server Trello MCP server" /></a>

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.

Highlights

• 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.

Installation

The server is published on npm as @delorenj/mcp-server-trello. Add it to your MCP client and you're done — no clone, no build.

Quickstart (Claude Desktop, Cursor, and other MCP clients)

Add the server to your client's MCP configuration:

{
  "mcpServers": {
    "trello": {
      "command": "bunx",
      "args": ["@delorenj/mcp-server-trello"],
      "env": {
        "TRELLO_API_KEY": "your-trello-api-key",
        "TRELLO_TOKEN": "your-trello-token"
      }
    }
  }
}

bunx starts fastest, but npx works identically. Get your API key at trello.com/app-key and generate a token from the same page.

Claude Code

Register the server with the CLI:

claude mcp add trello \
  --env TRELLO_API_KEY=your-trello-api-key \
  --env TR
