broadcast_on · It2 MCP: Risk & Policy

WHAT IT DOES

What broadcast_on does on It2mcp

AI agents invoke broadcast_on to trigger actions in It2mcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why broadcast_on needs a policy

This tool triggers an external operation that causes all subsequent terminal input to be sent to multiple sessions simultaneously. While it doesn't execute a specific command itself, it enables a multiplier effect where any subsequent keystrokes/commands are broadcast to all sessions, dramatically increasing blast radius.

Verdict

broadcast_on Rate-limited

broadcast_on stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
