Claude Desktop application

Installation

Clone the repository:

git clone <repository-url>
cd trello-mcp

Install dependencies:

npm install

Build the project:

npm run build

Authentication Setup

Get Trello API Credentials:
- Visit https://trello.com/app-key to get your API key
- Generate a token by visiting: https://trello.com/1/authorize?expiration=never&scope=read,write,account&response_type=token&name=Server%20Token&key=YOUR_API_KEY

Configure Environment: Create a .env file in the project root:

TRELLO_API_KEY=your_api_key_here
TRELLO_TOKEN=your_token_here

Integration Setup

Claude Desktop Integration

Add the following to your Claude Desktop configuration file:

macOS

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

Windows

Edit %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "trello": {
      "command": "node",
      "args": ["/path/to/trello-mcp/dist/index.js"],
      "env": {
        "TRELLO_API_KEY": "your_api_key_here",
        "TRELLO_TOKEN": "your_token_here"
      }
    }
  }
}

Docker Desktop Integration

Docker Desktop (v4.38+) includes built-in MCP server support through the Docker MCP Catalog and Toolkit. This provides the easiest way to run and manage MCP servers.

Option 1: Using Docker Desktop's Built-in MCP Support (Recommended)

Enable MCP in Docker Desktop:
- Open Docker Desktop (ensure version 4.38 or later)
- Go to Extensions → Browse → Search for "MCP"
- Install the Docker MCP Catalog and Toolkit extension

Publish to Docker Hub's MCP Catalog:

# Build and tag for MCP catalog
docker build -t mcp/trello-server .
docker push mcp/trello-server

Configure in Claude Desktop with Docker MCP:

{
  "mcpServers": {
    "trello": {
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "--env-file", ".env",
        "mcp/trello-server"
      ]
    }
  }
}

Use with Ask Gordon (Docker AI): Create gordon-mcp.yml in your project directory:

version: '3.8'
services:
  trello-mcp:
    image: mcp/trello-server
    environment:
      - TRELLO_API_KEY=${TRELLO_API_KEY}
      - TRELLO_TOKEN=${TRELLO_TOKEN}
    volumes:
      - ./logs:/app/logs

Then use Docker AI commands:

# Ask Gordon to help with Trello management
docker ai "Show me my Trello boards and create a new development task"

Option 2: Traditional Docker Setup

Create a Dockerfile in your project root:

FROM node:18-alpine

WORKDIR /app

COPY package*.json ./
RUN npm ci --only=production

COPY dist/ ./dist/

# Create non-root user for security
RUN addgroup -g 1001 -S nodejs
RUN adduser -S mcp -u 1001
RUN chown -R mcp:nodejs /app
USER mcp

EXPOSE 3000

CMD ["node", "dist/index.js"]

Build and run the container:

# Build the image
docker build -t trello-mcp-server .

# Run with Docker MCP Toolkit (secure credential management)
docker run -d \
  --name trello-mcp \
  --env-file .env \
  -p 3000:3000 \
  trello-mcp-server

# Or use docker-compose.yml:

Create docker-compose.yml:

version: '3.8'
services:
  trello-mcp:
    build: .
    container_name: trello-mcp-server
    environment:
      - TRELLO_API_KEY=${TRELLO_API_KEY}
      - TRELLO_TOKEN=${TRELLO_TOKEN}
      - LOG_LEVEL=info
      - API_TIMEOUT=10000
    ports:
      - "3000:3000"
    restart: unless-stopped
    volumes:
      - ./logs:/app/logs
    networks:
      - mcp-network

networks:
  mcp-network:
    driver: bridge

Run with Docker Compose:

# Set environment variables in .env file, then:
docker-compose up -d

Benefits of Docker Desktop MCP Integration

Built-in Security: OAuth support and secure credential storage
One-Click Setup: Seamless integration with Claude, Cursor, VSCode, and other MCP clients
Cross-Platform: Consistent behavior across different architectures
Isolation: Memory, network, and disk isolation for production-ready security
Discovery: Access to 100+ verified MCP tools from Docker Hub's MCP Catalog

Cursor IDE Integration

In Cursor, you can set up the MCP server for AI-assisted development:

Install Cursor Extension (if available):
- Open Cursor IDE
- Go to Extensions marketplace
- Search for "MCP" or "Model Context Protocol"
Configure MCP Server: Create .cursor/mcp-config.json in your workspace:

{
  "mcpServers": {
    "trello": {
      "command": "node",
      "args": ["./dist/index.js"],
      "cwd": "/path/to/trello-mcp",
      "env": {
        "TRELLO_API_KEY": "your_api_key_here",
        "TRELLO_TOKEN": "your_token_here"
      }
    }
  }
}

Use with Cursor AI:
- Open Cursor's AI chat panel
- The Trello MCP tools should be available for context
- Ask questions like: "Show me my Trello boards and help me organize my tasks"

Windsurf IDE Integration

For Windsurf IDE integration:

Project Configuration: Create .windsurf/settings.json:

{
  "mcp": {
    "servers": {
      "trello": {
        "command": "node",
        "args": ["dist/index.js"],
        "cwd": "${workspaceFolder}",
        "env": {
          "TRELLO_API_KEY": "your_api_key_here",
          "TRELLO_TOKEN": "your_token_here"
        }
      }
    }
  },
  "ai": {
    "providers": {
      "claude": {
        "mcpServers": ["trello"]
      }
    }
  }
}

Workspace Setup: Add to your .windsurf/workspace.json:

{
  "name": "Trello MCP Development",
  "description": "Development workspace with Trello integration",
  "mcpServers": ["trello"],
  "tools": {
    "trello": {
      "enabled": true,
      "autoStart": true
    }
  }
}

Usage in Windsurf:
- The AI assistant will have access to Trello tools
- Use natural language commands in the AI chat
- Example: "Create a development task board and add cards for the current project features"

Development Container (DevContainer)

For consistent development environments, create .devcontainer/devcontainer.json:

{
  "name": "Trello MCP Development",
  "build": {
    "dockerfile": "../Dockerfile.dev"
  },
  "forwardPorts": [3000],
  "postCreateCommand": "npm install && npm run build",
  "customizations": {
    "vscode": {
      "extensions": [
        "ms-vscode.vscode-typescript-next",
        "esbenp.prettier-vscode",
        "bradlc.vscode-tailwindcss"
      ],
      "settings": {
        "mcp.servers": {
          "trello": {
            "command": "node",
            "args": ["dist/index.js"],
            "env": {
              "TRELLO_API_KEY": "${TRELLO_API_KEY}",
              "TRELLO_TOKEN": "${TRELLO_TOKEN}"
            }
          }
        }
      }
    }
  },
  "remoteEnv": {
    "TRELLO_API_KEY": "${localEnv:TRELLO_API_KEY}",
    "TRELLO_TOKEN": "${localEnv:TRELLO_TOKEN}"
  }
}

Create Dockerfile.dev:

FROM node:18

WORKDIR /workspace

# Install global tools
RUN npm install -g @modelcontextprotocol/inspector typescript

# Set up development environment
COPY package*.json ./
RUN npm install

# Copy source code
COPY . .

# Expose MCP server port
EXPOSE 3000

CMD ["npm", "run", "dev"]
