Top Show HN slot at 54 points: an MCP CLI client that connects to any stdio or HTTP server and emits Token-Optimized Object Notation instead of JSON schema, claiming 97% fewer tokens on tool discovery and 40–60% on results. The premise is that MCP overhead runs 40,000–70,000 tokens before any reasoning happens, eating 30–55% of a 128K window. Zero-dependency pure Python, ~50KB, Apache 2.0. The savings figures are the author's own and unverified by anyone else, so measure before you believe.
