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.
