Deja Vu MCP Server

Memory for coding agents, starting with the history you already have. Your agent is about to re-debug something you fixed in March. deja indexes the sessions Claude Code, Codex, Cursor and every other agent on this machine already wrote to disk, and hands the right one back when it is needed. It runs locally over stdio via the published package.

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Go.

01 · Install Deja Vu

Claude Code

claude mcp add vshulcz-deja-vu -- npx -y @vshulcz/deja-vu

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "vshulcz-deja-vu": {
      "command": "npx",
      "args": [
        "-y",
        "@vshulcz/deja-vu"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
