The full upstream README, mirrored here for reference. Install config, tool schemas, adoption signals, and an original overview live on the Talkback listing page.
Chat with your Ableton session in natural language. Go deeper in your mix, make it sound like it does in your head, and finally understand compression... jk no one can teach you that.
Talkback is an MCP server and Max for Live device that gives AI assistants real-time access to your Ableton Live session — read tracks, adjust parameters, analyze your mix, and get spectral snapshots, all through conversation.

The fastest way to get set up — installs the MCP server and configures Claude Desktop automatically:
Already in an AI agent? Let it set things up for you:
Then ask your agent: "Help me set up talkback"
Requires Node.js 18+. See the full setup guide for more options.
Download talkback-bridge (latest) and drop it onto your master track in Ableton. Make sure the device is toggled on.
Talkback requires a desktop MCP client — it runs locally on your machine and connects to Ableton over WebSocket. It does not work with claude.ai in the browser (web chat doesn't support local MCP servers yet).
Download Claude Desktop, then add to your config:
~/Library/Application Support/Claude/claude_desktop_config.json (macOS)
%APPDATA%\Claude\claude_desktop_config.json (Windows)
Restart Claude Desktop after saving.
Using nvm or fnm? Claude Desktop doesn't load your shell profile, so it may pick up an old system Node. Use the full path to
npxinstead — runwhich npxin Terminal, then set that as"command"in the config above. See troubleshooting for details.
Add to .cursor/mcp.json in your project root:
Point your client at npx -y talkback-mcp as the server command with WS_PORT=8765 as an environment variable.
Or use add-mcp to auto-configure all your installed agents:
Open your LLM and start asking about your session:
Your LLM will ask for approval before making any parameter changes. Undo always works.
