DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude can list your installed and running Mac apps before asking to control one.

list_apps
What

When Claude is driving individual Mac apps, it can now list installed and running applications to find the right identifier before asking for access. Parameters are query, running_first (default true), limit (default 25, maximum 200) and an opaque cursor for paging.

Details
  • Declared as having no side effects and callable before any app has been granted.
  • Offered only when the host is app-scoped and the platform is macOS; on other platforms the call path answers list_apps is not available on this platform.
Evidence

list_apps is not available on this platform.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
