Suno MCP

MCP server for generating music with your suno.com account — no third-party API keys, no 2Captcha, no extra paid services.

Use it from Cursor, Claude Desktop, or any MCP-compatible client to check credits, generate songs, and download MP3s.

Features

• Your Suno account — uses your existing subscription/credits
• No API middlemen — authenticates via Clerk in a real browser session
• Generation tools — custom lyrics/style or simple prompt mode
• Library access — credits, recent songs, status polling, MP3 download

Requirements

• Python 3.10+
• A free or paid Suno account at suno.com
• Chromium (installed via Playwright)

Quick Start

Install from PyPI

pip install suno-mcp
playwright install chromium
cp .env.example .env  # optional — defaults work out of the box

Install from source

git clone https://github.com/David-J-Shibley/suno-mcp.git
cd suno-mcp
python3 -m venv .venv
source .venv/bin/activate
pip install -e .
playwright install chromium
cp .env.example .env

First run: A browser window opens. Log into Suno if prompted. Your session is saved to ~/.suno-mcp/browser-profile.

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "suno": {
      "command": "/absolute/path/to/suno-mcp/.venv/bin/python",
      "args": ["-m", "suno_mcp"],
      "env": {
        "SUNO_HEADLESS": "false"
      }
    }
  }
}

Set SUNO_HEADLESS to false — the Create button must be visible for generation to work.

Restart the MCP server after config or code changes (Cursor → Settings → MCP).

macOS Homebrew Python note

If pip fails with a pyexpat / libexpat error on macOS Tahoe, add to your MCP env:

"DYLD_LIBRARY_PATH": "/opt/homebrew/opt/expat/lib"

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "suno": {
      "command": "/absolute/path/to/suno-mcp/.venv/bin/python",
      "args": ["-m", "suno_mcp"],
      "env": {
        "SUNO_HEADLESS": "false"
      }
    }
  }
}

Tools

Tool	Description
suno_get_credits	Check your Suno credit balance
suno_get_recent	List recent songs in your library
suno_generate_song	Custom mode — lyrics + style
suno_generate_from_description	Simple mode — describe the song
suno_check_status	Poll generation status by song ID
suno_wait_for_songs	Wait until songs are ready
suno_download_song	Download MP3 to a folder

How It Works

1. Auth — Reads JWT from window.Clerk.session.getToken() in the logged-in browser tab.
2. Reads (credits, feed, recent) — Direct HTTPS to studio-api.prod.suno.com.
3. Generation — Fills lyrics/style via React state, then dispatches a trusted CDP mouse click on the Create button (required by hCaptcha).

Generation approach adapted from unforced/suno-mcp.

Configuration

Variable	Default	Description
SUNO_BROWSER_PROFILE_DIR	~/.suno-mcp/browser-profile	Persistent browser profile
SUNO_HEADLESS	false	Must be false for generation
SUNO_CDP_URL	—	Connect to existing Chrome via CDP
SUNO_DEBUG	—	Set to 1 for debug logging

Optional: Use Your Own Chrome

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
  --remote-debugging-port=9222 \
  --user-data-dir=~/.suno-mcp/chrome-profile

Then in .env:

SUNO_CDP_URL=http://localhost:9222

Log into Suno in that Chrome window.

Troubleshooting

Not signed in — Log into suno.com/create in the browser window the MCP server opens.

Profile already in use — Restart the Suno MCP server in Cursor (only one browser instance per profile).

Empty song IDs after generate — Keep SUNO_HEADLESS=false, ensure the browser window stays visible, and restart the MCP server after updates.

Cookie dialog — Click "Allow All" once if Suno shows a privacy/cookie banner.

Limitations

• Unofficial — Uses Suno's internal endpoints; may break when Suno updates.
• Browser required — Generation needs a visible browser window.
• Uses your Suno credits — Same quota as the website.
• MVP scope — No covers, extends, or stems yet.
