WHAT IT DOES

What email_reply does on FlowDot MCP Server

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

RISK

Why email_reply is rated Medium

Sending a reply to an email creates new outbound communication. This is a Write action (creates a new message) rather than Destructive or Execute. Misuse could lead to sending unauthorized replies on behalf of the user, hence medium severity. The permission qualifier 'Subject to mailbox grant permissions' confirms it performs an action on an external system.

RECOMMENDED RULE

The rule that runs email_reply 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_reply, this is the rule to start with:

email_reply Rate-limited

email_reply 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.
