WHAT IT DOES

What set_clipboard does on AirMCP

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

RISK

Why set_clipboard is rated Medium

This tool modifies system state (clipboard) reversibly. While not Read (retrieves data), it is Write rather than Execute because it does not run arbitrary code or trigger complex external operations—it simply replaces clipboard content with provided text.

From the tool's definition Tool name 'set_clipboard' and description explicitly states 'Write text to the system clipboard, replacing its current content' — a direct modification operation that creates/overwrites clipboard state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set_clipboard safely

PolicyLayer is an MCP gateway: it sits between your AI agents and AirMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_clipboard, this is the rule to start with:

set_clipboard Rate-limited

set_clipboard 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.
