Our reading of Code Graph Rag, from the data

Code Graph Rag is a memory MCP server from er77.

We haven't measured its tool list yet, so its token cost is unknown.

It looks abandoned: the newest commit, release or package publish we found was 4 months ago (2026-06-12). For comparison, 68% of memory servers are active or maintained.

With 122 GitHub stars it ranks #97 of 1,597 memory servers we index.

It runs locally on your machine over stdio.
