I have been bolting retrieval hacks onto my coding agent for months, and most of them trade accuracy for token bloat. This is the first one that did the opposite. I indexed a 400k-line codebase, wired the MCP server into Claude Code, and the agent stopped grepping at random. It started asking for the call graph and getting answers in one round trip.

The token savings are not marketing. On a refactor that used to balloon the context window, the agent pulled the three functions it needed and left the rest on disk. Sub-millisecond queries mean no pause while it thinks. The knowledge graph view also helps me when I am trying to learn an unfamiliar service.

What sold me was how little ceremony it needed. Download the binary, run the install, restart the agent. No external database, nothing leaving my machine. If you run agents against a large repo and you are tired of watching them rediscover the structure every session, try this.
