Claude Desktop Setup

  1. Install Claude Desktop

    • Download Claude Desktop
    • Ensure you have the latest version (Menu: Claude -> Check for Updates...)

  2. Configure MCP Server

    {
  "mcpServers": {
    "joplin": {
      "command": "/PATH/TO/UV/uv",
      "args": [
        "--directory",
        "/PATH/TO/YOUR/PROJECT/joplin_mcp",
        "run",
        "src/mcp/joplin_mcp.py"
      ]
    }
  }
}
    • Replace /PATH/TO/UV/uv with the absolute path to your uv installation
      • Find the path with: which uv
      • Example macOS: /Users/username/.local/bin/uv
      • Example Windows: C:\Users\username\AppData\Local\Microsoft\WindowsApps\uv.exe
    • Replace /PATH/TO/YOUR/PROJECT/joplin_mcp with the absolute path to your project

    Important: Claude Desktop needs the full path to uv as it cannot access shell environment variables.
