Monomem: shared local memory for Claude Code and other agents, with poisoning drills
Mother-Side6477 · reddit · 2026-11-10
A developer built Monomem, an MIT-licensed local tool that gives Claude Code, Codex, and Cursor a shared memory layer without blindly trusting any single agent's writes — no AI calls on save.
Key features:
- npx monomem setup wires it into each app (also installs as a Claude Code plugin)
- Every note is stamped with its writer; writes matching known attack patterns require human approval
- monomem why <note> shows a note's full history
- monomem drill tests 22 known memory-poisoning attacks against your setup
- v1.3 adds private notes and per-app visibility limits
- Honest limits: reworded attacks and shell-capable agents aren't caught
