WHAT IT DOES

What send_email does on Freshdesk

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

RISK

Why send_email is rated Medium

Sending emails creates new messages that are stored and transmitted, representing a reversible write operation. While not inherently destructive, emails can have significant business impact (e.g., sending to wrong recipients, unauthorized communications) warranting high severity. The Freshdesk context suggests customer-facing communications, elevating the severity of misuse.

From the tool's definition Tool name 'send_email' and description 'Send a new email message' indicate creation of new email communications.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs send_email safely

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

send_email Rate-limited

send_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.
