MailboxValidator

Security checks across malware telemetry and agentic risk

Overview

This is a read-only MailboxValidator connector skill that sends email addresses through OOMOL to validate deliverability, with no hidden code or automatic persistence found.

Install this if you want agents to validate email addresses through your OOMOL-connected MailboxValidator account. Treat email addresses as personal data, and review any first-time `oo` CLI installation or account-connection step before allowing it.

Finding
The skill description says to use this skill for ANY MailboxValidator request and instead of calling the API directly, which is an overly broad routing rule. This can cause an agent to invoke the skill in situations where direct API use, tighter-scoped tools, or additional validation would be safer, increasing the blast radius of mistakes and making prompt-triggered misuse easier.
