General · SubverseLab
Loom is the production system behind SubverseLab's own records: a local MCP server that reads your own Ableton projects and library, answers with counts instead of guesses, and writes MIDI, device chains, automation and markers into a running Live session — verifying every write by reading it back. It is 59 tools across seven engines. It is in beta and open while it is being built, the source is public, and it is listed in the MCP Registry. macOS only, and it needs Live 12.4 beta for the extension. Details at subverselab.com/loom.
