Anlyon alternative

1 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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

Changes things 1Claude Code: ask
Only reads 2Show 2 read-only tools
  • get_songDetails for one GrooveSheet song: every part and what notation it has.No findings

    Why it is in this group

    • The name "get_song" says "get": a word for reading.
    Description, as the server wrote it
    Details for one GrooveSheet song: every part and what notation it has. Each part is `sheet_music` (readable score, PDF, Guitar Pro), `midi_only` (MIDI transcription, no score) or `audio_only` (isolated stem). Includes the song page URL and, for each scored part, its sheet music page.

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
    • readOnlyHint: true
    • title: Get GrooveSheet song details
  • search_songsSearch GrooveSheet's public library of AI-transcribed songs by title or artist.No findings

    Why it is in this group

    • The name "search_songs" says "search": a word for reading.
    Description, as the server wrote it
    Search GrooveSheet's public library of AI-transcribed songs by title or artist. Returns up to 10 songs per page with id, title, artist, the separated instruments, whether the song has sheet music / MIDI / stems, and the song page URL. Track-level flags only: call get_song for which specific parts are scored, since a song can have sheet music for one part and only MIDI for another.

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
    • readOnlyHint: true

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.

1 warn
  • Warnget_download_links

    The server marks "get_download_links" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "get_download_links" says "get": a word for reading.

    What this check looks for

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.

All changes to this server

Install

Pinned to version 2.2.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http groovesheet https://api.groovesheet.net/mcp/public
claude mcp add --transport http groovesheet https://api.groovesheet.net/mcp/public

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__groovesheet__search_songs",
      "mcp__groovesheet__get_song"
    ],
    "ask": [
      "mcp__groovesheet__get_download_links"
    ],
    "deny": []
  }
}

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 groovesheet. 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.
