resend_verification_code · AdButler MCP: Risk & Policy

WHAT IT DOES

What resend_verification_code does on AdButler

WHY IT NEEDS A POLICY

Why resend_verification_code needs a policy

This tool triggers an external operation (sending an email) rather than simply reading or writing data. It causes a side effect in an external system (email delivery). The blast radius is low since misuse only results in sending an extra verification email, but it is categorized as Execute because it triggers an external operation whose effects depend on the state of the account.

From the tool's definition 'Resend the email verification code' and 'Use this if the user did not receive the code or it expired'

resend_verification_code Rate-limited

resend_verification_code 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.
