Claude Setup

Config File

Update Claude Desktop MCP config (commonly ~/Library/Application Support/Claude/claude_desktop_config.json on macOS) and merge into existing mcpServers:

{
  "mcpServers": {
    "flutter-inspector": {
      "command": "/ABSOLUTE/PATH/mcp_flutter/mcp_server_dart/build/flutter_inspector_mcp",
      "args": [
        "--dart-vm-host=localhost",
        "--dart-vm-port=8181",
        "--resources",
        "--images",
        "--dynamics"
      ],
      "env": {},
      "disabled": false
    }
  }
}

Validation

1. Restart Claude Desktop.
2. Ask Claude to:
   • list available tools
   • get extension RPCs and confirm ext.mcp.toolkit.app_errors/view_details/view_screenshots/inspect_widget_at_point exist
   • capture a screenshot
   • get view details for current layout
   • retrieve app errors

If Calls Fail

Use AI troubleshooting, especially target selection with arguments.connection.targetId.
