Knowledge graph for token-efficient code reviews -- semantic search and call-graph resolution across your codebase.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
Renamed (2026-09-13): repo is nowcrg— CLI-first (crgcommand). PyPI package staysbetter-code-review-graph; MCP server is a secondary surface.

Questions
What is the crg MCP server?
Knowledge graph for token-efficient code reviews -- semantic search and call-graph resolution across your codebase.
Is crg safe to connect to an agent?
No — not without reading the findings first. The audit graded it D (69/100) and found 1 critical or high issue in the source. Each one is listed on this page with the file and line it is on.
What credentials does crg need?
It reads API_KEYS, HULL_CHAT_API_KEY, HULL_EMBED_API_KEY and SECRET from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does crg run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on PyPI as better-code-review-graph.
How current is this page?
The grade is for one exact copy of the source (774c77ae238f), read on 2026-10-07. The repository is watched and re-audited when it changes.
