Then let your coding agent fix it

Connect your coding agent to the MCP server, and it can read the same data, find the cause and change your code.

Why is GET /api/users slow in production?

  • worst_performing_transactions shop-api
  • transaction_details GET /api/users

N+1 query in UserController@index. It loads offices once per user, which adds 6 queries to every request.

app/Http/Controllers/UserController.php
- $users = User::all();+ $users = User::with('offices')->get();
