A code graph for Claude Code cut my investigation tokens by 59%

AI coding agents burn tokens reconstructing codebase structure on every session: grep, read, grep again, piece together what a symbol graph already knows. I built CodeGraph, a local MCP server that parses a repo with tree-sitter and exposes a pre-computed call graph to Claude Code through six tools. I use it daily to keep Claude Code token bills sane. A headless benchmark on a 484-file FastAPI…
