Chat is not working on my project. It does have a lot of files but the chat steaight up won’t work. I tried using max, using auto, renamed the project, reinstall cursor, nothing is working.
Steps to Reproduce
Have a large project.
Expected Behavior
Chat should respond.
Operating System
MacOS
Current Cursor Version (Menu → About Cursor → Copy)
Hey, thanks for the report. Large projects can definitely cause chat issues, that’s normal.
This often happens if a large file is open in Cursor, even if it’s not used in context. Try closing that file or switching to another one.
If you have MCP servers enabled, temporarily disable the ones you don’t need right now.
Use .cursorignore, it works like .gitignore. Create this file in your project root and add paths to folders and files you don’t need in context (for example, node_modules, build folders, etc). This will significantly reduce context size and speed up Cursor.
It’s also recommended to split large files into smaller modules with imports, Cursor works better with smaller files.
If none of this helps, open the DevTools panel and check for errors. That will help pinpoint the issue.
