Deja Vu MCP Server

The one memory your coding agents share, built from the history already on your disk. It runs locally over stdio via the published package.

People who work with codex, opencode and agent memory and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Go.
