mcp-server-trello

A Model Context Protocol (MCP) server that provides tools for interacting with Trello boards. This server enables seamless integration with Trello's API while handling rate limiting, type safety, and error handling automatically.

• Added Docker support with multi-stage build
• Improved security by moving environment variables to .env
• Added Docker Compose configuration
• Added .env.template for easier setup

• Added move_card tool to move cards between lists
• Improved documentation

• Initial release with basic Trello board management features

• Full Trello Board Integration: Interact with cards, lists, and board activities
• 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
• Error Handling: Graceful error handling with informative messages

The easiest way to run the server is using Docker:

1. Clone the repository:

git clone https://github.com/delorenj/mcp-server-trello
cd mcp-server-trello

2. Copy the environment template and fill in your Trello credentials:

cp .env.template .env

3. Build and run with Docker Compose:

docker compose up --build

To install Trello Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @modelcontextprotocol/mcp-server-trello --client claude

npm install @delorenj/mcp-server-trello

The server can be configured using environment variables. Create a .env file in the root directory with the following variables:

TRELLO_API_KEY=your-api-key

TRELLO_BOARD_ID=your-board-id

You can get these values from:

• API Key: https://trello.com/app-key
• Token: Generate using your API key
• Board ID: Found in the board URL

  }
}

{
  name: 'get_lists',
  arguments: {}
}

{
  name: 'get_recent_activity',
  arguments: {

  }
}

{
  name: 'add_card_to_list',
  arguments: {
    listId: string,       // ID of the list to add the card to

The server implements a token bucket algorithm for rate limiting to comply with Trello's API limits:

• 300 requests per 10 seconds per API key
• 100 requests per 10 seconds per token

Rate limiting is handled automatically, and requests will be queued if limits are reached.

The server provides detailed error messages for various scenarios:

• Invalid input parameters
• Rate limit exceeded
• API authentication errors
• Network issues
• Invalid board/list/card IDs

• Node.js 16 or higher
• npm or yarn
