What it does

Install

With Claude. Open the .mcpb file: Claude Desktop installs it. Then give Timbre Full Disk Access; ask Claude to open Timbre's permission settings and it shows you where. To make Claude reach for Timbre unasked, add the skill in Claude's settings.

With other assistants. Open the .zip, then Timbre: it puts itself in Applications, lists the assistants found on your Mac and connects the ones you tick. Installed this way, it keeps itself up to date from this page, and only with a release signed by the same developer and notarized by Apple.

Developed and tested on macOS 27 with Apple Silicon. Built to run on macOS 12 and later, Intel included: write if it does not on yours.
