midi

midi is an MCP server for Claude Code from os-tack/fcp. Its token cost is not measured, scanned A, a copy of midi, MIT.

A local tool that gives an AI assistant structured understanding of MIDI files. MIDI is a digital format that stores musical notes, timing, instruments, and performance instructions rather than recorded sound.

In plain words
What is it for?
Use it for MIDI-related composition and other tasks that require understanding or changing musical note information.
Why use it?
It lets the assistant work with musical compositions as editable note data instead of treating them as opaque files.

Security

Grade A, and why

midi scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to midi — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
