MCP & AI Assistants

What is the Spatial9 MCP connector?

The Spatial9 MCP connector is a remote Model Context Protocol (MCP) server that lets any AI assistant turn songs and videos into immersive 3D audio. You add one address to ChatGPT, Claude, Gemini, Grok, Claude Code, Cursor or any other app that accepts MCP connectors, then ask in plain words. Spatial9 returns Eclipsa Audio (IAMF), binaural headphone WAV, YouTube-ready MP4 and separate instrument tracks.

Free address, no account: https://spatial9.ai/mcp/free. Account address, uses your Spatial9 plan: https://spatial9.ai/mcp.

The free version includes:

• 3 chorus previews
• 1 video in spatial audio
• 1 ADM to Eclipsa Audio conversion
• 1 instrument split

How it works

1. Add one address: Paste spatial9.ai/mcp/free into your assistant as a connector. No account, no install.
2. Ask in plain words: Say what you want to hear. Your assistant gives you an upload link if the file is on your computer.
3. Listen and download: Get a headphone preview first, then every file: Eclipsa Audio, MP4, binaural WAV and stems.

Where it works

• Chat assistants: ChatGPT, Claude, Gemini, Grok. Add Spatial9 as a connector, then ask in the chat.
• Coding and agent tools: Claude Code, Cursor, VS Code, Codex, Gemini CLI. One command or config line, then use it from your agent.
• Open model apps: Qwen, Kimi, DeepSeek, LM Studio, Any MCP client. Any app with MCP settings: paste the address or a config block.

Use Spatial9 with your DAW

• Into your DAW, Split, then produce: Spatial9 separates a finished song into instrument tracks. Drop them into Pro Tools, Logic Pro, Ableton Live, REAPER, Nuendo, Cubase, FL Studio or Bitwig to remix, rebalance or build an Atmos session. Try: "Split my song into vocals, drums, bass and other instruments, and give me the download links."
• Out of your DAW, Master once, deliver everywhere: Export the ADM BWF master from your Dolby Atmos session and let Spatial9 turn it into Eclipsa Audio for YouTube, with no remix and no extra plugin. Try: "Convert my ADM master (.wav) into Eclipsa Audio for YouTube."
• Alongside your DAW, Two connectors, one conversation: Community MCP servers already exist for Ableton Live, REAPER, Logic Pro and Bitwig. Connect one next to Spatial9 and your assistant can hand the stems from one to the other. Try: "Split this song with Spatial9, then import the stems into new tracks in my Ableton session."

Trust

• You approve every connection: Account connections open a Spatial9 sign-in screen. Apps without sign-in use a private key you can revoke anytime.
• Fair limits, refunds on failure: Each render uses one project from your plan and is refunded if it fails. Up to 3 at a time and 20 per day.
• Unlisted links, kept until you delete them: Download links are not published or indexed, but anyone who has a link can open that file, so share them only with people you trust. Files made through an assistant are kept until you ask us to delete them, unlike regular uploads, which are removed after 30 days.
• Built on an open standard: MCP is the open protocol shared by every major AI assistant, so one connector works everywhere.
