Overview

Trello MCP Server (delorenj/mcp-server-trello) is the most popular community implementation of the Model Context Protocol for Trello. It bridges AI coding assistants directly to the Trello REST API, enabling full read/write access to boards, lists, cards, checklists, comments, attachments, and activity.

Powered by Bun (since v1.5.0 for 2.8–4.4× performance), it includes built-in rate limiting, type safety, dynamic multi-board/workspace switching, and robust error handling.

Key Features

Board & Workspace Tools: List boards/workspaces, dynamic active board/workspace switching with persistence
Card Operations: Create, update, move, archive, get full details (including checklists, labels, members, comments, attachments)
List Management: Retrieve, add, and archive lists
Checklist Tools: Full CRUD + smart features like get acceptance criteria and search items by description
Comments: Add, update, delete, and retrieve comments
Attachments: Upload images/files from URLs or local file:// paths
Additional: Get my cards, recent activity, Markdown export, rate limiting (300 req/10s per key)

How It Works

Generate Trello API Key (trello.com/app-key) and Token
Configure and run the MCP server (local or via registry)
Connect to your AI agent
Prompt naturally, e.g., “Create a new card in the To Do list for the landing page redesign with due date next week and attach this screenshot” or “Move all high-priority cards to Doing and add a comment”
