I use Cursor daily, I have worked on Agents using LangChain. Maybe we are doing something wrong but even ysing SOTA models unless we explicitly give which mcp tool to call, it uses anything - sometimes - while other times it can do a passavle job. So now our mandate is to spell everything out to LLM so it doesn't add a non existent column like created at or updated at to our queries

I've used every SOTA for day to day work, and at best they save some effort. They can't do everything yet
