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:

Example Usage

Here's how an AI assistant can interact with Trello through this MCP server:

Natural Language Commands

• "Show me all my Trello boards" → Lists all available boards

• "Find the 'Project Alpha' board" → Searches for a specific board by name

• "What lists are in my project board?" → Retrieves all lists within a board

• "Create a new task card in the 'To Do' list" → Adds a new card to a specific list

• "Update the 'Fix bug' card description" → Modifies existing card details

• "Move the 'Review PR' card to 'Done'" → Moves cards between lists

• "Add a comment to card XYZ" → Adds comments to existing cards

• "Delete the completed card ABC" → Removes cards from boards

Workflow Management

The MCP server enables AI assistants to help with:

• Project tracking: Moving cards through workflow stages

• Task management: Creating, updating, and organizing cards

• Team collaboration: Adding comments and managing card assignments

• Board organization: Structuring lists and managing board content

Limitations
