MCP Client Configuration

Claude Desktop Configuration

To use this server with Claude Desktop, add the following to your Claude Desktop MCP configuration file:

Location: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS)

{
  "mcpServers": {
    "trackjs": {
      "command": "node",
      "args": ["/absolute/path/to/trackjs-mcp/dist/index.js"],
      "env": {
        "TRACKJS_API_KEY": "your_trackjs_api_key_here",
        "TRACKJS_BASE_URL": "https://api.trackjs.com/v1"
      }
    }
  }
}

Important: Replace /absolute/path/to/trackjs-mcp/ with the actual path to this project directory.

Alternative: Using .env file

If you prefer to use the .env file approach (recommended), configure like this:

{
  "mcpServers": {
    "trackjs": {
      "command": "node",
      "args": ["/absolute/path/to/trackjs-mcp/dist/index.js"],
      "cwd": "/absolute/path/to/trackjs-mcp"
    }
  }
}

This way, the server will automatically load environment variables from your .env file.

After adding the configuration:

1. Restart Claude Desktop

2. The TrackJS tools should be available in your Claude conversations
