WHAT IT DOES

What send_mail does on Iconnect

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

RISK

Why send_mail is rated Medium

This tool creates new email messages and sends them, which is a reversible write operation (emails can be unsent in some contexts, but typically constitute committed communication). While emails can cause harm if misused by an AI agent (spam, phishing, impersonation), the operation itself is Write rather than Execute or Destructive.

From the tool's definition Tool description explicitly states 'Compose and send an email' — a write operation that creates and transmits messages.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs send_mail safely

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

send_mail Rate-limited

send_mail 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Iconnect, apply this rule, and every send_mail call is checked against it from then on.
