WHAT IT DOES

What register_clip does on vidMagik-mcp

WHY IT NEEDS A POLICY

Why register_clip needs a policy

This tool creates a new entry (registers a clip) in the server's global state and returns an identifier. This is a reversible write operation—the clip registration can be undone or cleared. It does not execute arbitrary code, delete data, move money, or trigger external side effects. The scope is limited to internal state management within the video editing context.

From the tool's definition Tool description states it 'Registers a clip in the global state and returns its ID', which is a create/record operation that modifies internal state.
