maxmsp is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from gluon/max-mcp-server. Its token cost is not measured, scanned A, original, MIT.

A local MCP server that connects an AI assistant to Max/MSP, a visual environment for making music and audio systems. It runs a Python server and uses three network settings to communicate with Max.

In plain words
What is it for?
Use it to start the Max/MSP integration with the configured host and ports, enabling the related patch-building and control tools.
Why use it?
It provides the configured connection needed for an assistant to interact with Max/MSP. Without the server and its ports, the assistant cannot use the described Max integration.

Security

Grade A, and why

maxmsp 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 3d 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.

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.
