deja-vu
deja-vu is an MCP server. It reaches deja and openai. It needs DEJA_EMBED_KEY and OPENAI_API_KEY to authenticate. Its repository has 1,299 GitHub stars and is licensed under MIT; we last read it on 2026-10-24.
Serves as a shared memory among multiple coding agents, drawing from session history stored locally. Fixes discovered in one agent are available in all agents, even those from past sessions. No external language models or embeddings are used; it relies on a local Go binary.
Install
Read from deja-vu’s own README, close to verbatim -- not written by us, and not guessed.
curl -fsSL https://raw.githubusercontent.com/vshulcz/deja-vu/main/install.sh | sh
What it reaches, and what it needs
What it connects to
Unverified means a mention in the server’s own description, not a citation. A wrong claim here costs nothing to correct and nothing to trust yet.
Maintenance
Coding agent memory for Claude Code, Codex, Cursor and 39 more, built from the session history already on your disk. Local search, MCP and hooks, no LLM, one Go binary.
