send_sales_email · Sales Agent MCP: Risk & Policy

WHAT IT DOES

What send_sales_email does on Sales Agent

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

WHY IT NEEDS A POLICY

Why send_sales_email needs a policy

The tool almost certainly sends emails via SendGrid based on the server description. Sending emails is a Write/Execute action with high blast radius — an AI agent could spam targets or send inappropriate content to real recipients. The description is empty, so confidence is reduced, but the server context strongly implies this tool triggers outbound email delivery.

From the tool's definition Tool name 'send_sales_email'; server description mentions 'sends personalized sales emails via SendGrid'
