   {
     "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
