WHAT IT DOES

What add_contact_email does on AirMCP

AI agents use add_contact_email 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 add_contact_email is rated Medium

This tool modifies existing contact information reversibly. While the operation itself is not destructive (the change can be undone or corrected), it does alter stored data in the contacts system. The severity is medium because misuse could add incorrect contact information, potentially disrupting communication, but the blast radius is limited to a single contact's email field.

From the tool's definition Tool name is 'add_contact_email' and description states 'Add an email address to an existing contact' — this creates or modifies contact data by appending an email address to a contact record.

add_contact_email Rate-limited

add_contact_email stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
