Trello MCP Server

A Model Context Protocol (MCP) server that provides AI assistants with access to Trello's functionality. This server enables AI models to interact with Trello boards, lists, and cards programmatically.

Prerequisites

• Node.js >= 18.0.0
• npm or yarn package manager
• Trello API credentials (API key and token)

Installation

1. Clone this repository:

git clone <repository-url>
cd trello_mcp_server

2. Install dependencies:

npm install

3. Build the project:

npm run build

Configuration

Getting Trello API Credentials

To use this MCP server, you need to obtain your Trello API key and token. Follow these steps:

1. Visit the Trello REST API documentation
2. Follow the instructions to create a Power-Up and generate your API credentials
3. Once you have your API key and token, you'll add them to your MCP client configuration

MCP Client Configuration

This is an MCP (Model Context Protocol) server that needs to be configured in your MCP client (Cursor or Claude Desktop).

For Cursor

Add the following configuration to your Cursor MCP settings:

{
  "mcpServers": {
    "trello-mcp-server": {
      "type": "stdio",
      "command": "node",
      "args": ["<path_to_this_project>/trello_mcp_server/dist/index.js"],
      "env": {
        "TRELLO_API_KEY": "your_api_key",
        "TRELLO_TOKEN": "your_token"
      }
    }
  }
}

For Claude Desktop

Add the following configuration to your Claude Desktop MCP settings:

{
  "mcpServers": {
    "trello-mcp-server": {
      "type": "stdio",
      "command": "node",
      "args": ["<path_to_this_project>/trello_mcp_server/dist/index.js"],
      "env": {
        "TRELLO_API_KEY": "your_api_key",
        "TRELLO_TOKEN": "your_token"
      }
    }
  }
}

Important Notes:

• Replace <path_to_this_project> with the absolute path to your cloned repository
• Replace your_api_key and your_token with your actual Trello credentials
• Make sure the path points to the compiled dist/index.js file

Usage

Once configured in your MCP client (Cursor or Claude Desktop), the Trello MCP server will be automatically available to AI assistants. You can then interact with Trello through natural language commands like:

• "Show me all my Trello boards"
• "Create a new card in my project board"
• "Move the 'Fix bug' card to the 'In Progress' list"
• "Add a comment to card XYZ"

Using with MCP Inspector

To inspect and test the MCP server:

npm run inspect
