Anlyon alternative
3 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Deletes or cancels 2Claude Code: deny
redo_stemMake one stem of a finished song again (new drums, say), with the other four exactly as they are; the mix becomes the new part with the rest.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Make one stem of a finished song again (new drums, say), with the other four exactly as they are; the mix becomes the new part with the rest. Counts as one song. Takes about a minute; the player shows it. undo_stem puts the old part back.
Annotations the server declares
- readOnlyHint: false
- openWorldHint: false

undo_stemPut a song's version back to how it was before its last redo_stem: the old part plays again, and the mix with it.No findings
Why it is in this group
- The description's first verb is "put": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it Put a song's version back to how it was before its last redo_stem: the old part plays again, and the mix with it. Costs nothing. Only the last redo can be undone.

Changes things 1Claude Code: ask
create_songMake an original instrumental song from a description: genre, mood, instruments, tempo, what it's for.No findings
Why it is in this group
- The name "create_song" says "create": a word for a change.
Description, as the server wrote it Make an original instrumental song from a description: genre, mood, instruments, tempo, what it's for. Returns it queued; the player in the chat shows it rendering and plays it when it's done (about a minute), with MP3 and WAV downloads and its five stems (drums, bass, guitar, keys, other) as FLAC. Where there's no player, get_song gives those links once it's done. No artist names: describe the sound instead. Royalty-free, for commercial games and videos.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
Install

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__music__get_song",
"mcp__music__list_songs",
"mcp__music__get_songs_left"
],
"ask": [
"mcp__music__create_song"
],
"deny": [
"mcp__music__redo_stem",
"mcp__music__undo_stem"
]
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as music. Review it before you use it.
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
