Cursor IDE gives maximum size error

Hey, thanks for the report. This error happens when the data being sent to the server exceeds a 50 MB limit, which can occur as a conversation accumulates context (files, tool outputs, etc.). This is a known issue our team is working on.

A few things to try:

  1. Check if HTTP/2 is disabled — Open Settings (CMD + ,), search for “HTTP/2”. If “Disable HTTP/2” is toggled on, turn it off. With HTTP/1, data gets encoded less efficiently and can hit the size limit faster.

  2. Start a new chat — If your current conversation has built up a lot of context, opening a fresh chat should clear the issue.

  3. Exclude large files from context — If your project contains large files (binaries, images, PDFs, etc.), create a .cursorignore file in your project root to exclude them, similar to .gitignore.

Others have reported the same issue with some additional workarounds here.

Let me know if any of the above helps!
