Feature request for product/service

Cursor IDE

Describe the request

Cursor stores all chat, agent, and composer state in a single SQLite
database (state.vscdb). This database grows without bound — there is no
automatic pruning, no VACUUM, no lifecycle management. After weeks of
normal use, the file balloons to multiple GB.

The impact is brutal:

  • Every read/write traverses massive B-trees
  • WAL grows unchecked (checkpoint deferred for large DBs)
  • The main process writes GB/min to the WAL file
  • I/O storms cause CPU spikes, UI freezes, and terminal lag
  • ‘Taking longer than expected’ on every AI request
  • Eventually the editor becomes unusable — frozen for 10+ seconds between
    keystrokes

This is not a niche issue. It hits every heavy user. The fix is mechanical:
prune stale agentKv:blob:, composer., bubbleId:* rows from cursorDiskKV,
then VACUUM. This reduces a 5+ GB database to ~50 MB in seconds.

REQUEST:

  1. Automatic state.vscdb maintenance — prune stale entries and VACUUM
    periodically (or on startup)
  2. Configurable retention — let users set how long chat/agent history is
    kept
  3. At minimum, expose a manual ‘Clean Database’ command in the command
    palette

Until this is built in, I wrote cursor-clean — a Python toolkit that
diagnoses, cleans, and repairs the problem from the terminal:

It works. But users should not need a third-party tool to keep their editor
functional.

WHAT PROBLEM DOES THIS SOLVE:

Cursor becomes unusable after extended use due to unbounded state.vscdb
growth. Users on remote VMs, VNC setups, or machines without dedicated GPUs
are hit hardest — the software rendering already pushes CPU, and the I/O
storms from the bloated database make it unrecoverable without manual
intervention.

Operating System (if it applies)

Linux

hey, my solution to this was to create a copy, then directly ask cursor to check what was inside and go through with me and delete stuff that was safe.. when I had something I liked, just tell cursor to check if the file is still safe, if yes just put in back in the original file, and keep the old one just in case

Hi there, 3.7.36 is good thank you so much now I can play

yes please add :folded_hands: I have an agent manually clean db but it would be wonderful to have a setting for chat retention and to auto-clean.
