Compress MCP tool discovery with the mcptoon CLI. Trigger when a session has a large MCP tool catalog (many servers/tools), when the user mentions token cost, tool discovery, mcptoon, or asks to list/call MCP tools efficiently. Also route here when the user says the MCP tool list is too large, the agent context window is filling up with tool schemas, or they need the same MCP servers configured across Claude Code, Cursor, Codex, Cline, Windsurf and other agents. Also covers managing an agent's…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# mcptoon — MCP tool-catalog compression ## Step 0 — is it installed? (do this before anything else) **Before you run any `mcptoon …` command below, check that the CLI is actually on this machine.** The skill travels alone: agents and dotfiles repos copy this one file, and the binary is not part of the copy. So the common failure is an agent holding this skill on a machine where `mcptoon` does not exist — it then reads the commands as instructions, tries them, and they fail. ```bash mcptoon --version # if this prints a version, skip to the next section ``` If that fails, do **not** keep going through the tables below — install it first: ```bash pip install mcptoon # or: uvx mcptoon … / pipx install mcptoon ``` `uvx mcptoon <args>` runs it with no install at all, if `uvx` is available. Then say one plain sentence to the user — for example *"this skill is installed but the mcptoon CLI is not; I installed it"* — and continue. Never silently pretend the commands worked, and never tell the user the feature is unavailable when a one-line install is the whole gap. mcptoon is a zero-dependency CLI (565KB, installs in seconds, nothing else pulled …

How to install
mdr add activeing123/mcptoon/mcptoon@sha256:d7243add23250fc5The line at the top of this page pins the label v1.4.3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
