What this MCP does

Analyzes, previews, cleans, and masters audio tracks, including loudness normalization and AI-generated audio fingerprint removal.

Capabilities

Tools

11 tools
analyze_track
Analyze a track
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.

batch_master
Master an album or a batch
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_limits
Check quota and balance
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_trace
Remove Suno/Udio AI fingerprint
Strip the AI generator fingerprint without mastering; loudness and tone stay as they are. Free. Returns a job id — poll get_job.

create_topup_link
Create a top-up link
Prepare a token purchase for the human principal. The agent CANNOT complete the payment: card and Telegram Stars both need the human. Returns the checkout link to hand over, then poll check_limits.

get_job
Get job status
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.

Service info
What Magic Master does, what is free, what costs a token, and where the rules live. Call once at the start of a session.

Input schema 
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema 
{'type': 'object', 'description': 'Service manifest: endpoints, presets, live prices, limits, policies.'}
list_presets
List mastering presets
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.

master_track
Master a track
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.

preview_styles
Compare presets on 24 seconds
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.
