git clone https://github.com/kocakli/trello-desktop-mcp.git cd trello-desktop-mcp

- Visithttps://trello.com/app-key
- Copy your API Key
- Generate a Token (never expires, read/write access)

{ "mcpServers": { "trello": { "command": "node", "args": ["/absolute/path/to/trello-desktop-mcp/dist/index.js"], "env": { "TRELLO_API_KEY": "your-api-key-here", "TRELLO_TOKEN": "your-token-here" } } } }

Add the server using the Claude Code CLI:

claude mcp add trello -- node /absolute/path/to/trello-desktop-mcp/dist/index.js \ -e TRELLO_API_KEY=your-api-key-here \ -e TRELLO_TOKEN=your-token-here

Or add it to your project's.mcp.json:

{ "mcpServers": { "trello": { "command": "node", "args": ["/absolute/path/to/trello-desktop-mcp/dist/index.js"], "env": { "TRELLO_API_KEY": "your-api-key-here", "TRELLO_TOKEN": "your-token-here" } } } }

Edit your Gemini CLI settings file at~/.gemini/settings.json:

{ "mcpServers": { "trello": { "command": "node", "args": ["/absolute/path/to/trello-desktop-mcp/dist/index.js"], "env": { "TRELLO_API_KEY": "your-api-key-here", "TRELLO_TOKEN": "your-token-here" } } } }

Any MCP-compatible client that supports stdio transport can use this server. You need to configure it to:
- Runnode /absolute/path/to/trello-desktop-mcp/dist/index.js
- Set environment variablesTRELLO_API_KEYandTRELLO_TOKEN

Refer to your client's documentation for the exact configuration format.

Restart your MCP clientto pick up the new configuration.

The MCP server provides 19 tools organized into three phases:

- trello_search- Universal search across all Trello content
- trello_get_user_boards- Get all boards accessible to the current user
- get_board_details- Get detailed board information with lists and cards
- get_card- Get comprehensive card details
- create_card- Create new cards in any list

- update_card- Update card properties
- move_card- Move cards between lists
- trello_add_comment- Add comments to cards
- trello_get_list_cards- Get all cards in a specific list
- trello_create_list- Create new lists on boards

- trello_get_board_cards- Get all cards from a board with filtering
- trello_get_card_actions- Get card activity history
- trello_get_card_attachments- Get card attachments
- trello_get_card_checklists- Get card checklists
- trello_get_board_members- Get board members
- trello_get_board_labels- Get board labels
- trello_get_member- Get member details

- list_boards- List user's boards
- get_lists- Get lists in a board

Once configured, you can use natural language with your AI assistant to interact with Trello:

"Show me all my Trello boards" "Create a new card called 'Update documentation' in the To Do list" "Move card X from In Progress to Done" "Add a comment to card Y saying 'This is ready for review'" "Search for all cards with 'bug' in the title" "Show me all cards assigned to me"

The server implements the Model Context Protocol (MCP), which provides:

- Standardized tool discovery and invocation
- Type-safe parameter validation
- Structured error handling
- Automatic credential management

- API credentials are stored locally in your MCP client's config
- No credentials are transmitted over the network
- All Trello API calls use HTTPS
- Rate limiting is respected with automatic retry logic

- TypeScript for type safety
- MCP SDK for protocol implementation
- Zod for schema validation
- Fetch API for HTTP requests

The server includes comprehensive error handling and validation. Test your setup by:
- Checking your MCP client's connection status
- Running a simple command like "Show me my Trello boards"
- Verifying the response includes your board data

- Ensure your MCP client is fully restarted after configuration
- Check that the path in config points todist/index.js
- Verify the file exists and is built

- Double-check your API key and token
- Ensure token has read/write permissions
- Regenerate token if needed

- The server includes automatic retry logic
- Wait a few minutes if you hit limits
- Consider reducing request frequency

Check your MCP client's logs for connection and error details. For Claude Desktop, logs are at:

- macOS:~/Library/Logs/Claude/mcp-server-trello.log
- Windows:%APPDATA%\Claude\Logs\mcp-server-trello.log
- Fork the repository
- Create a feature branch
- Add tests for new functionality
- Submit a pull request
