Magic Master MCP — Audio Mastering for AI Agents

Remote MCP server that provides audio mastering services to MCP clients. It targets LUFS loudness and True Peak limiting, removes Suno/Udio AI fingerprints, and returns a “mastering passport” within the chat session. The server is accessible over streamable HTTP and uses defined protocol dates.

🛠️ Key Features

Audio mastering with LUFS target control
True Peak limiting
Suno/Udio AI-fingerprint removal
“Mastering passport” response in chat
Server endpoint: https://magicmaster.pro/mcp

🚀 Use Cases

Master audio intended for AI agents
Post-processing tracks to meet LUFS and True Peak targets
De-fingerprinting audio associated with Suno/Udio

⚡ Developer Benefits

Works with MCP clients (e.g., Claude, ChatGPT, Cursor, VS Code, Claude Code)
Streamable HTTP access
OAuth endpoint for paid tools: https://magicmaster.pro/mcp/oauth
Registry entry: pro.magicmaster/mastering

⚠️ Limitations

Does not specify supported input/output formats, tool names, or configuration details beyond LUFS/True Peak and fingerprint removal

Magic Master MCP — audio mastering for AI agents

Remote MCP server that lets Claude, ChatGPT, Cursor, VS Code, Claude Code and any other MCP client master audio: hit a LUFS target with True Peak limiting, strip the Suno / Udio AI fingerprint, and get a mastering passport back in the chat.

Server: https://magicmaster.pro/mcp (streamable HTTP, protocol 2026-07-28, also 2025-11-25 / 2025-06-18)
OAuth endpoint for paid tools: https://magicmaster.pro/mcp/oauth
Registry entry: pro.magicmaster/mastering
Agent playbook: https://magicmaster.pro/agents.md · machine manifest: https://magicmaster.pro/agent.json
Human page (RU/EN): https://magicmaster.pro/mcp

Nothing to install: the server is hosted. This repository holds the connection recipes and a tiny stdio bridge for clients that cannot speak HTTP.

One-click install

Connect

Claude Code

bash

claude mcp add --transport http magicmaster https://magicmaster.pro/mcp

claude.ai / Claude Desktop (custom connector, OAuth): Settings → Connectors → Add custom connector → URL https://magicmaster.pro/mcp/oauth → sign in on the consent page. Use https://magicmaster.pro/mcp if you only need the free tools.

Claude Desktop (claude_desktop_config.json)

json

{ "mcpServers": { "magicmaster": { "type": "http", "url": "https://magicmaster.pro/mcp" } } }

Cursor (.cursor/mcp.json)

{ "mcpServers": { "magicmaster": { "url": "https://magicmaster.pro/mcp" } } }

VS Code (.vscode/mcp.json)

ChatGPT (Developer mode → Connectors → Create): URL https://magicmaster.pro/mcp/oauth, authentication OAuth.

stdio-only clients — bridge through mcp-remote:

json

{ "mcpServers": { "magicmaster": { "command": "npx", "args": ["-y", "mcp-remote", "https://magicmaster.pro/mcp/oauth"] } } }

or the npm package — npx -y magicmaster-mcp (magicmaster-mcp on npm), a one-line wrapper around the same bridge:

json

{ "mcpServers": { "magicmaster": { "command": "npx", "args": ["-y", "magicmaster-mcp"] } } }

Docker

For clients without Node, and for the Glama build that runs security checks:

bash

docker build -t magicmaster-mcp .
docker run -i --rm magicmaster-mcp

The image holds only the bridge — the server itself stays hosted at https://magicmaster.pro/mcp. It is built from this repository (npm ci), so mcp-remote is baked in and the container needs no registry at run time — only outbound HTTPS to magicmaster.pro. The image defaults to the anonymous endpoint (free tools, no sign-in); switch it to the OAuth endpoint, which also unlocks the paid tools, with -e MAGICMASTER_MCP_URL=https://magicmaster.pro/mcp/oauth.

Build spec for a Glama release (the platform configures the recipe on its side, it does not read this Dockerfile):

build steps: npm ci --omit=dev
start command: node bin/magicmaster-mcp.js
environment: MAGICMASTER_MCP_URL=https://magicmaster.pro/mcp

Tools

Tool	What it does	Cost
`analyze_track`	LUFS, true peak, duration, correlation, genre hint	free
`clean_ai_trace`	removes the Suno / Udio digital fingerprint, loudness untouched	free
`master_track`	mastering: 24 presets, LUFS target, 6 export formats	1 token
`get_job`	status + result metrics, with a mastering passport widget (MCP Apps)	free
`check_limits`	balance, remaining free quota, reset time	free
`list_presets`, `get_pricing`, `get_service_info`	presets with target loudness, live prices, service manifest	free
`create_topup_link`	prepares a checkout for the human — the agent cannot pay by itself	free

Typical flow: analyze_track → (clean_ai_trace for AI-generated tracks) → master_track → poll get_job. A master takes 20–60 s.

Access and pricing

Free tools need no account.
Mastering: 3 per month per IP without an account, 1 per day with a free account.
Register an agent once (POST /api/agents/register) and get 3 trial masters; afterwards 1 token = 1 full PRO master. Tokens never expire. Live prices: GET /api/tokens/packages.
Rules for agents, error codes and the payment protocol: https://magicmaster.pro/agents.md.
