app_activate · It2 MCP: Risk & Policy

WHAT IT DOES

What app_activate does on It2mcp

AI agents invoke app_activate 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 app_activate needs a policy

This tool triggers an external operation on the iTerm2 application — bringing it to the foreground. It doesn't read data, write/modify data, or destroy anything, but it does execute an action that affects the state of the operating environment (window focus/activation). Misuse potential is low since it only changes which app is in focus.

Verdict

app_activate Rate-limited

app_activate 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.
