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

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.
