WHAT IT DOES

What email_send does on FlowDot MCP Server

AI agents invoke email_send to trigger actions in FlowDot MCP Server. 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 email_send is rated High

Sending an email is an external operation that cannot be recalled once dispatched. It is not merely writing data in a system but triggering an outbound communication to third parties. This makes it Execute (external operation), and potentially high severity since a misused agent could send phishing, spam, or sensitive information to arbitrary recipients via the connected mailbox.

From the tool's definition 'Send an email through a connected mailbox' — triggers an external communication operation with real-world side effects

RECOMMENDED RULE

The rule that runs email_send safely

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

email_send Rate-limited

email_send 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.
