Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account systemblueio for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Lets an assistant control a REAPER digital audio workstation session in plain language, with writes verified against REAPER feedback.

What you can do: This server connects an assistant to a running REAPER session so it can carry out digital audio workstation operations from natural-language instructions. According to the registry description, it operates the session in plain language and verifies write actions against feedback returned by REAPER. The manifest does not list individual tools, so the exact command set is not documented here.
When to use it: Worth adding when you work in REAPER and want an assistant to drive session actions for you rather than clicking through the interface yourself. It is a desktop-only local server, so it suits a workstation setup rather than a headless or web environment.
Requirements: Runs as a local process on the user's machine over stdio, distributed as an mcpb package. Desktop only; no web executable. No authentication, environment variables, or headers are declared, but a REAPER installation must be present and running for the server to operate a session.

Before you install

The server performs write operations in a REAPER session, which can change or overwrite project content; the description says writes are verified against REAPER feedback, but you should still keep backups of important projects. No credentials, payments, or third-party data sharing are declared.

Installation

In SourceWeft

Open DeadCat: Reaper in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
