jgravelle/jcodemunch-mcp shipped v1.108.170 today at 2,174 stars, using tree-sitter AST parsing to store only signatures, kinds, qualified names and byte offsets, then fetching a requested symbol's implementation directly from source rather than reading whole files. It reports 99.6% aggregate savings across 15 benchmark task-runs, 15-25% isolated savings in production A/B tests, and 335B+ tokens saved via telemetry. The gap between 99.6% and 15-25% is the number to trust, and it's the second one. The licensing is the actual news: free for non-commercial only, with Builder ($79), Studio ($349) and Platform ($1,999) tiers. Paid commercial licenses are starting to appear on MCP servers.
