jcodemunch-mcp Ships v1.108.170 Today Claiming 99.6% Token Savings via Tree-Sitter Symbol Retrieval — and Charges $79–$1,999 for Commercial Use

GitHub·medium signal

jgravelle/jcodemunch-mcp released v1.108.170 on 2026-07-25 and sits at 2,174 stars (+47 today). It uses tree-sitter AST parsing to store only signatures, kinds, qualified names, and byte offsets, then fetches a requested symbol's implementation directly from source rather than reading whole files, reporting 99.6% aggregate savings across 15 benchmark task-runs on three public repos, 15–25% isolated savings in production A/B tests, and 335B+ tokens saved via live telemetry. The licensing is the story for builders: free for non-commercial use only, with Builder ($79), Studio ($349), and Platform ($1,999) tiers — commercial paid licenses are starting to appear on MCP servers, and the gap between the 99.6% benchmark and the 15–25% production A/B figure is the number to trust.
