DeadCat: Reaper

If you're producing audio in REAPER and want to drive your session from Claude, this server exposes 25 OSC-backed tools that let you start playback, record takes, adjust mix levels, and query session state in plain language. Every write is verified against REAPER's own OSC feedback instead of fire-and-forget UDP, so you know the command landed. The session cache keeps REAPER's state synchronized for reads. It's built for music production and podcast editing workflows where you'd rather describe what you want than click through menus. Runs locally over stdio, nothing leaves your machine. The same codebase powers a standalone terminal command if you don't need the MCP layer.
