Features

• Store code snippets and notes as Trello cards

• Search across card titles, descriptions, and labels

• Organize knowledge by boards and lists

• Tag-based categorization using Trello labels

• Full CRUD operations on your knowledge base

Setup

Prerequisites: Make sure you have direnv installed for environment variable management.

1. Get Trello API credentials:

   • First, create a Power-Up at https://trello.com/power-ups/admin (required for API access)

   • Go to your Power-Up's "API Key" tab and generate a new API key

   • Generate a Token by clicking the Token link (its hidden in the text)

   • Copy both your API Key and Token

2. Create a Knowledge Board:

   • Create a new Trello board for your knowledge base

   • Create lists like "Code Snippets", "Configuration", "Notes", etc.

   • Copy the board ID from the URL

3. Configure environment with direnv:

   # Edit .envrc with your Trello credentials
   # Make sure direnv is installed and allowed for this directory
   direnv allow

4. Install and run:

   npm install
   npm start

5. Configure Claude Desktop: Add this to your Claude Desktop configuration file:

   macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json Linux: ~/.config/Claude/claude_desktop_config.json

   {
     "mcpServers": {
       "trello-knowledge": {
         "command": "node",
         "args": ["src/index.js"],
         "cwd": "/path/to/your/trello-mcp-server",
         "env": {
           "TRELLO_API_KEY": "your_api_key_here",
           "TRELLO_TOKEN": "your_token_here",
           "TRELLO_KNOWLEDGE_BOARD_ID": "your_board_id_here"
         }
       }
     }
   }

   Windows PowerShell (if Node.js isn't in PATH):

   {
     "mcpServers": {
       "trello-knowledge": {
         "command": "C:\\Program Files\\nodejs\\node.exe",
         "args": ["C:\\Users\\YourUsername\\path\\to\\trello-mcp-server\\src\\index.js"],
         "env": {
           "TRELLO_API_KEY": "your_api_key_here",
           "TRELLO_TOKEN": "your_token_here",
           "TRELLO_KNOWLEDGE_BOARD_ID": "your_board_id_here"
         }
       }
     }
   }

   Alternative with direnv (if you want Claude Desktop to inherit your shell environment):

   {
     "mcpServers": {
       "trello-knowledge": {
         "command": "bash",
         "args": ["-c", "cd /path/to/your/trello-mcp-server && eval \"$(direnv export bash)\" && node src/index.js"],
         "cwd": "/path/to/your/trello-mcp-server"
       }
     }
   }

6. Restart Claude Desktop for the changes to take effect.
