mcptoon

Add 1,000 MCP tools and 1,000 agent skills locally — your token context never feels it. (measured on my own machine: 255 tools / 371 skills)

mcptoon is a 189KB CLI — think of it as a steward that takes over every MCP tool and skill on your machine, and keeps both out of your context window.

① Token — it keeps both MCP tool schemas and skill files out of your agent's context. Tools: 71,929 → 581 tokens (−99.2% measured). Skills: 926,000 → 501 tokens to find the right one, with only 39 resident (−99.9% measured). Call results shrink another ~34% with --toon.

② Setup — install mcptoon once, and every AI on your machine gets all your MCP tools and skills. Add a tool or a skill later and it goes live immediately — no agent restart.

👉 Your own numbers, 30s: pip install mcptoon && mcptoon bench — it measures what your tools and skills cost, on your machine.

👉 Or just watch it work: uvx mcptoon demo --quick — 255 tools, 71,929 tokens of schemas → a 581-token name list (−99.2%). (demo needs Node)

This isn't just us talking

Those numbers are ours, but "loading every tool schema into context is expensive" is not a claim only we make:
