How do I use IRCAM Amplify MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@IRCAM Amplify MCP Server analyze this track's genre and mood: https://soundcloud.com/artist/track.mp3" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

IRCAM Amplify MCP Server

MCP (Model Context Protocol) server for IRCAM Amplify audio processing APIs. Enables any MCP-compatible LLM to analyze music, separate stems, detect AI-generated audio, and more.

Features

Music Analysis: Extract genre, mood, tempo, key, and instruments from audio
Stem Separation: Split audio into vocals, drums, bass, and other instruments
AI Detection: Detect whether music is AI-generated or human-made
Loudness Analysis: Measure LUFS, true peak, and dynamic range
Async Job Handling: Poll long-running operations with progress tracking

Supported Audio Formats

MP3, WAV, FLAC, OGG, M4A (max 100MB)

Quick Start

Prerequisites

Node.js 18+ (download)
IRCAM Amplify API Key from app.ircamamplify.io

Installation

npm install -g ircam-amplify-mcp

Or run directly with npx:

npx ircam-amplify-mcp

Configuration

1. Set your API key

export IRCAM_AMPLIFY_API_KEY="your-api-key-here"

Usage Examples

Analyze a song

"Analyze this song: https://example.com/song.mp3"

Response:

{

  "key": "A minor",
  "instruments": ["synthesizer", "drums", "bass"]
}

Separate stems

"Separate the vocals from this track: https://example.com/track.mp3"

Response (sync for short files):

{
  "vocals_url": "https://cdn.ircamamplify.io/stems/vocals.wav",
  "drums_url": "https://cdn.ircamamplify.io/stems/drums.wav",
  "bass_url": "https://cdn.ircamamplify.io/stems/bass.wav",
  "other_url": "https://cdn.ircamamplify.io/stems/other.wav"
}

Response (async for longer files):

{
  "job_id": "abc123-def456"
}

Check if AI-generated

"Is this track AI-generated? https://example.com/mystery.mp3"

Response:

{
  "confidence": 85,
  "classification": "ai_generated"
}

Classification values: ai_generated, human_made, or uncertain

Analyze loudness

"Check if this master is ready for Spotify: https://example.com/master.wav"

Response:

{
  "integrated_lufs": -14.0,
  "true_peak_db": -1.0,
  "loudness_range": 6.0
}

Check job status

"Check the status of job abc123-def456"

Response:

{
  "status": "completed",
  "progress": 100,
  "result": {
    "vocals_url": "...",
    "drums_url": "...",
    "bass_url": "...",
    "other_url": "..."
  }
}

Status values: pending, processing, completed, failed

Error Handling

The server provides detailed error messages with actionable suggestions:

Error Code	Meaning	Suggestion
`MISSING_API_KEY`	API key not configured	Set `IRCAM_AMPLIFY_API_KEY` environment variable
`INVALID_API_KEY`	API key rejected	Verify key at app.ircamamplify.io
`INVALID_URL`	Cannot access audio URL	Ensure URL is publicly accessible
`UNSUPPORTED_FORMAT`	Audio format not supported	Use MP3, WAV, FLAC, OGG, or M4A
`FILE_TOO_LARGE`	File exceeds 100MB limit	Use a shorter audio clip
`RATE_LIMITED`	Too many requests	Wait and retry
`JOB_NOT_FOUND`	Job ID invalid or expired	Job results expire after 24 hours
