mcptoon

mcptoon is a zero-dependency Python command-line tool that scans and unifies MCP (Model Context Protocol) tool configurations across multiple AI agents. It reduces tool manifest size from full JSON schemas to names-only format, cutting token usage by approximately 99.2% on reference fixtures and compressing call outputs an additional 34% with TOON encoding.

Designed for developers running multiple AI agents like Claude, Cursor, and others, mcptoon eliminates per-agent setup by creating a single shared configuration that works everywhere. Users install it once, and any new tools added sync automatically across all agents. The tool includes a browser-based token calculator and provides local statistics on actual token savings without uploading data.
