WHAT IT DOES

What email_label does on FlowDot MCP Server

AI agents use email_label 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_label is rated Medium

Adding or removing labels on an email is a reversible modification of email metadata. It does not delete data or execute code, placing it firmly in the Write category. Severity is medium because misuse could mis-categorize or hide emails at scale, but the action is reversible.

From the tool's definition 'Add or remove labels on an email message' — modifies metadata on an existing email; reversible action

RECOMMENDED RULE

The rule that runs email_label 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_label, this is the rule to start with:

email_label Rate-limited

email_label 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.
