What the publisher says

From the Trello repository's README, as published. We do not edit it. Read it on GitHub

MCP Server Trello

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: getacceptancecriteria pulls a card's AC checklist straight into your agent's context — no competitor offers it.
  • Watch anything: watchcard and watchlist route card and list activity into your Trello notifications.
  • Full list management: create, update, reorder (updatelistposition), 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.

Changelog

For a detailed list of changes, see CHANGELOG.md.

Features

  • Full Trello Board Integration: Interact with cards, lists, and board activities
  • Acceptance Criteria Extraction: Pull a card's acceptance criteria checklist directly into agent context
  • Checklist Intelligence: Query checklist items by name or description, track completion, manage items
  • Complete Card Data Extraction: Fetch all card details including checklists, attachments, labels, members, and comments
  • 💬 Comment Management: Add, update, delete, and retrieve comments on cards
  • Activity Subscriptions: Watch cards and lists so their activity surfaces in Trello notifications
  • List Management: Create, update, reorder, and archive lists
  • File Attachments: Attach any type of file to cards (PDFs, documents, videos, images, etc.) from URLs
  • Custom Fields: Read board custom field definitions and update card values
  • Built-in Rate Limiting: Respects Trello's API limits (300 requests/10s per API key, 100 requests/10s per token)
  • Type-Safe Implementation: Written in TypeScript with comprehensive type definitions
  • Input Validation: Robust validation for all API inputs

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:

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.

Install directly

Runs npx -y @delorenj/mcp-server-trello on your machine. Read the scan report first; the gateway never runs local packages.
