WHAT IT DOES

What sendgrid_send_email does on Integrations MCP

AI agents invoke sendgrid_send_email to trigger actions in Integrations MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why sendgrid_send_email is rated High

Sending an email is an external operation with real-world consequences (messages delivered to recipients). It fits 'Execute' as it triggers an external operation. The description is empty, so classification is based on the name alone, but 'send_email' is unambiguous. Severity is high because a misused tool could send spam, phishing, or sensitive content to arbitrary recipients at scale via SendGrid.

From the tool's definition Tool name 'sendgrid_send_email' — 'send_email' implies triggering an external email delivery operation via SendGrid API.

RECOMMENDED RULE

The rule that runs sendgrid_send_email safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Integrations MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sendgrid_send_email, this is the rule to start with:

sendgrid_send_email Rate-limited

sendgrid_send_email stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
