Reaper MCP Server

This is a simple MCP server that connects a Reaper project to an MCP client like Claude Desktop and enables you to ask questions about the project.

Tools

• find_reaper_projects: Finds all Reaper projects in the directory you specified in the config.
• parse_reaper_project: Parses a Reaper project and returns a JSON object.

These tools work in tandem. When you ask Claude a question about a specific Reaper project, it will use the find_reaper_projects tool to find the project, then use the parse_reaper_project tool to parse the project and answer your question. To see all data that is parsed from the project, check out the src/domains/reaper_dataclasses.py file.
