WHAT IT DOES

What gws_gmail_send does on AirMCP

AI agents use gws_gmail_send 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 gws_gmail_send is rated Medium

Sending emails is a reversible write operation that modifies external state (adds messages to recipient inboxes, creates sent mail records). It has high severity because an AI agent with access could send fraudulent emails, phishing messages, spam, or impersonate the user to contacts.

From the tool's definition Tool name explicitly states 'send' and description confirms it sends an email via Gmail. The RFC 2822 encoding preparation indicates actual message transmission capability.
