talkback mcp
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.

How it works
Ableton Live ↔ M4L Bridge ↔ WebSocket ↔ MCP Server ↔ Claude / Cursor / etc.
- talkback bridge — a Max for Live device on your master track that reads the Live Object Model and streams session data over WebSocket
- talkback-mcp (this package) — an MCP server that exposes your session as tools any LLM can use
Quick start
The fastest way to get set up — installs the MCP server and configures Claude Desktop automatically:
curl -fsSL https://talkback.createwcare.com/install.sh | bash
Already in an AI agent? Let it set things up for you:
npx skills add jmedure/talkback-mcp
Then ask your agent: "Help me set up talkback"
Requires Node.js 18+. See the full setup guide for more options.
1. Install the Max for Live device
Download talkback-bridge (latest) and drop it onto your master track in Ableton. Make sure the device is toggled on.
2. Add the MCP server
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)
{
"mcpServers": {
"talkback-mcp": {
"command": "npx",
"args": ["-y", "talkback-mcp"],
"env": { "WS_PORT": "8765" }
}
}
}
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.
claude mcp add --transport stdio talkback-mcp -- npx -y talkback-mcp
Add to .cursor/mcp.json in your project root:
{
"mcpServers": {
"talkback-mcp": {
"command": "npx",
"args": ["-y", "talkback-mcp"],
"env": { "WS_PORT": "8765" }
}
}
}
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:
npx add-mcp "npx -y talkback-mcp"
3. Start chatting
Open your LLM and start asking about your session:
- "What's going on in my session?"
- "My bass sounds muddy, can you help?"
- "Cut 3 dB at 300 Hz on the vocal EQ"
- "Does my mix have any obvious problems?"
Your LLM will ask for approval before making any parameter changes. Undo always works.
