   • Windows: code $env:AppData\Claude\claude_desktop_config.json

3. Edit the Claude for Desktop config file, located at:

   • macOS:

     {
       "mcpServers": {
         "mercari": {
           "command": "uv",
           "args": [
             "--directory",
             "/ABSOLUTE/PATH/TO/PARENT/FOLDER/mercari-jp-mcp",
             "run",
             "server.py"
           ]
         }
       }
     }

         "mercari": {
           "command": "uv",
           "args": [
             "--directory",
             "C:\\ABSOLUTE\\PATH\\TO\\PARENT\\FOLDER\\mercari-jp-mcp",

             "server.py"
           ]
         }
       }
