WHAT IT DOES

What send_location does on PyWA MCP Server

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

WHY IT NEEDS A POLICY

Why send_location needs a policy

This tool sends location data via WhatsApp, which creates a new message artifact with side effects (location is transmitted to a recipient). This is reversible communication (message can be deleted) rather than permanent data destruction. The impact is moderate—an agent could spam locations or send to wrong recipients, but lacks financial consequences or permanent data destruction.

From the tool's definition Tool name 'send_location' combined with server description stating it 'Provides comprehensive WhatsApp Business API functionality with... tools for sending messages, media, interactive buttons/lists, templates, reactions'.
