ReaperMCP

180 tools across 26 modulescover the full workflow: MIDI composition and patterns, a vocal-chop pipeline, FX and automatic genre-tuned mixing/mastering (35 style profiles), sends and routing, and post-production QC — batch editing, ReaScript automation, silence/click detection.

No cloud. Nothing leaves your machine.ReaperMCP runs entirely locally through a file-based Lua IPC bridge inside REAPER — your project, audio, and MIDI stay on your computer. Bring whatever AI client you already use (Claude Desktop, Claude Code, Cursor, any MCP client) — ReaperMCP handles REAPER.

Option A:Click the greenCodebutton above →Download ZIP→ extract to a folder — works with nothing pre-installed, easiest on a brand new machine.

Option B:Clone with git (lets yougit pullfor updates later):

A fresh Windows install doesn't ship with git — check first:

If that says "not recognized", install it, then close and reopen your terminal:

winget install --id Git.Git -e --source winget

macOS/Linux almost always have git already —git --versionto check, orbrew install git/sudo apt install gitif not.

git clone https://github.com/xDarkzx/Reaper-MCP.git

Option C:Already have Python? Install the published package straight from PyPI:

Windows:either double-clickinstall.batin File Explorer, or — if you're already in a terminal from thegit clonestep above — just keep going in the same PowerShell/Command Prompt window:

The installer installsreaper-mcplocally and optionallyconfigures Claude Desktop— no manual JSON editing needed.

Install manually withpip install -e .from the repo folder (orpip install xdarkzx-reaper-mcpfrom PyPI) and add to your client's MCP config:

{ "mcpServers": { "reaper": { "command": "reaper-mcp" } } }

Check your client's MCP documentation for the config file location.

Used the one-click installer?Already done — it sets up REAPER to auto-load the script on every launch. Just open (or restart) REAPER.
- OpenREAPER
- Go toActions → Show action list
- ClickLoad ReaScript...
- Navigate toreaper_scripts/reaper_mcp_server.luaand select it
- ClickRun

"Create 4 tracks: strings, brass, piano, and drums" "Compose an 8-bar orchestral string arrangement in D minor" "Add ReaEQ to the piano track and cut the low end below 200Hz" "Set the tempo to 90 BPM and loop the first 8 bars"

REAPER must be open with the Lua script running.ReaperMCP communicates through file-based IPC — it can't launch REAPER for you.
