batch_masterMaster up to 10 tracks in one call with the same settings.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.
Description, as the server wrote it
Master up to 10 tracks in one call with the same settings. Needs N TOKENS for N tracks, or N free runs — not one. album_mode (default true) levels the tracks RELATIVE to each other: the loudest hits the target exactly, the others keep their offsets, so a quiet interlude is not inflated to single level. Limits: 10 tracks, 100 MB per file and 300 MB per call (this server's own caps, for memory) — the account may allow bigger uploads on the site, but not through this channel. A big album takes minutes — send fewer, longer tracks per call rather than all at once. Returns one job id per track — poll each with get_job. Pass dry_run=true to see the price and the settings before anything is spent.

check_limitsWhat this account may do right now: token balance, free quota left and when it resets, upload cap, whether PRO modules are available.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 read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
What this account may do right now: token balance, free quota left and when it resets, upload cap, whether PRO modules are available. Call before mastering.

clean_ai_traceStrip the AI generator fingerprint without mastering; loudness and tone stay as they are.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.
Description, as the server wrote it
Strip the AI generator fingerprint without mastering; loudness and tone stay as they are. Free. Returns a job id — poll get_job.

  What this check looks for
Description, as the server wrote it
Prepare a token purchase for the human principal. The agent CANNOT complete the payment: the card payment needs the human. Returns the checkout link to hand over, then poll check_limits.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: true
master_trackMaster one track.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.
Description, as the server wrote it
Master one track. COSTS 1 TOKEN when the account has a balance; otherwise it runs on the free quota without PRO modules. Returns a job id immediately — poll get_job (typical 20-60 s, up to 10 min with restoration). The source is fetched by this server, so the ceiling here is 100 MB per file even when the account allows more. Pass dry_run=true first if you want the price and the effective settings before anything is spent.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- openWorldHint: true

Description, as the server wrote it
Master the middle 24 s of the track in 2-6 presets at once and get each one's loudness plus a listen link. FREE (6 per day). Use this instead of guessing a preset, and instead of burning a token to 'try' one.

analyze_trackMeasure integrated LUFS, sample peak, duration, sample rate and stereo correlation without processing.No findings
Why it is in this group
- The name "analyze_track" says "analyze": a word for reading.
Description, as the server wrote it
Measure integrated LUFS, sample peak, duration, sample rate and stereo correlation without processing. Free, a couple of seconds. Run this before choosing a preset. Note: true peak and loudness range are NOT part of this fast pass — they are measured on the result and come back from get_job.

  What this check looks for
Description, as the server wrote it
Status, progress and result metrics (after_lufs, true_peak_db, lra, platform_ready) for a mastering, cleanup or preview job. For previews it returns each style with its loudness and a listen link. When a master is done it also returns download_url — a signed link that works without credentials for about an hour, so an OAuth-connected agent can fetch the file it paid for. Free.

get_pricingLive token packs and payment methods.No findings
Why it is in this group

Live token packs and payment methods. Never quote prices from memory. Free.

Why it is in this group
- The name "get_service_info" says "get": a word for reading.
Description, as the server wrote it
What Magic Master does, what is free, what costs a token, and where the rules live. Call once at the start of a session.
Annotations the server declares

list_presetsAll mastering presets with their target loudness in LUFS.No findings
Why it is in this group
- The name "list_presets" says "list": a word for reading.
Description, as the server wrote it
All mastering presets with their target loudness in LUFS. Call this to get the exact preset keys that master_track and batch_master accept. Use preview_styles instead when you want to HEAR 2-6 of them on the actual track before choosing, and get_service_info when you need the wider service manifest rather than the preset list. Free.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- openWorldHint: false

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.

6 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.
