What obsidian_open_search_in_app does on Mcp Apple Obsidian

WHY IT NEEDS A POLICY

Why obsidian_open_search_in_app needs a policy

This tool triggers an external operation in the Obsidian application (opening the search UI with a query) via AppleScript or URI scheme. It doesn't merely retrieve data — it actively manipulates the running application's state. While the blast radius is low (it just opens a search panel), it executes an action in an external application rather than passively reading data.
