Suno-Hmnn-MCP

A local Model Context Protocol server for connecting Suno music workflows with AI clients and developer tools.

Developed by Sialki Labs. Licensed under the MIT License.

Music tools for an MCP client

The server exposes tools for music generation, track extension, clip metadata, stem requests, audio downloads, account credits, and authentication diagnostics. It also includes audio/MIDI-based generation tools and a local library backed by SQLite.

Availability depends on Suno's current service behavior, your account permissions, and the implementation in this repository. Review tool definitions and test the workflow with your account before relying on it.

Local setup

Requirements: Python 3.10 or later, Chrome or Edge, and a Suno account with access to the features you intend to use. Suno subscription charges and service limits are separate from this project's software license.

git clone https://github.com/SialkiLabs/Suno-Hmnn-MCP.git
cd Suno-Hmnn-MCP
pip install -r requirements.txt
playwright install chromium
python wizard.py

The wizard opens a browser for Suno sign-in and saves authentication material in a local .env file. Treat that file as a credential store, not an encrypted vault. Do not commit it, share it, or include it in support logs.

Connect an MCP client

Configure a client that supports local MCP processes to launch server.py. Use an absolute path and the Python executable from the environment where dependencies are installed.

{
  "mcpServers": {
    "suno-hmnn": {
      "command": "python",
      "args": ["/absolute/path/to/Suno-Hmnn-MCP/server.py"]
    }
  }
}

Clients use different configuration formats. Consult the client's documentation for the configuration location and process permissions. The local process can access resources allowed by the account that runs it.

How the server is organized

The implementation uses asynchronous HTTP requests, authentication handling, streamed file downloads, validated tool inputs, and local SQLite state. See server.py and core/ for the implementation rather than treating this overview as a performance or security certification.

Audio files and the library database use an OS-specific Music directory, such as ~/Music/SunoStudio. SUNO_OUTPUT_DIR controls the output directory.

Account access and security

This is an independent integration developed by Sialki Labs, not a claim of endorsement by Suno. It connects to remote services and is not air-gapped.

• Use only accounts and material you are authorized to access.

• Review Suno's terms, plan restrictions, and rights associated with generated content.

• No guarantee can be made against account restrictions or changes to service access.

• Protect cookies, tokens, .env, and local library contents.

• Review the code and dependencies before running the process on a machine with sensitive data.

Report vulnerabilities privately using SECURITY.md. Use Issues for reproducible bugs that do not disclose secrets.
