WHAT IT DOES

What clipboard_set does on Claude Mobile

AI agents use clipboard_set to create or update resources in Claude Mobile, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Mobile environment.

RISK

Why clipboard_set is rated Medium

This tool creates or modifies clipboard data, which is reversible and has no permanent side effects. It does not execute code, delete data, or move money. However, it is Write rather than Read because it changes system state.

From the tool's definition Tool name 'clipboard_set' and description 'Set clipboard text' indicate it modifies the clipboard state with new text content.

RECOMMENDED RULE

The rule that runs clipboard_set safely

clipboard_set Rate-limited

clipboard_set stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
