Claude Code

claude mcp add nickcirv-engram -- npx -y engramx

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "nickcirv-engram": {
      "command": "npx",
      "args": [
        "-y",
        "engramx"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

What is Engram?

Engram makes your AI coding agent stop re-reading the same files - and stop repeating mistakes your repo already fixed. It runs locally over stdio via the published package.

Is Engram still maintained?

Yes - as of 2026-08-25, its last commit was 2026-06-22 and it shipped 5 releases in the last 90 days. We re-verify nightly.

How do I install Engram?

Run `npx -y engramx`. The README documents 4 environment variables (ENGRAM_GREP_INTERCEPT, ENGRAM_READ_DEDUP, ENGRAM_MISTAKE_GUARD…) to set first. Set ENGRAM_GREP_INTERCEPT, ENGRAM_READ_DEDUP, ENGRAM_MISTAKE_GUARD, ENGRAM_NO_UPDATE_CHECK before connecting. You can also paste the ready-made client config above.

Does Engram run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
