rsvp_event · WhatsApp MCP Automation MCP: Risk & Policy

WHAT IT DOES

What rsvp_event does on WhatsApp MCP Automation

AI agents use rsvp_event to create or update resources in WhatsApp MCP Automation — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your WhatsApp MCP Automation environment.

WHY IT NEEDS A POLICY

Why rsvp_event needs a policy

RSVPing to an event creates or modifies a response record (accepting/declining an invite). This is a reversible write action — it updates your attendance status for an event. No data is deleted, no code is executed, and no financial transaction occurs. Misuse could commit the user to events without consent, hence medium severity.

rsvp_event Rate-limited
