WHAT IT DOES

What draft_email_reply does on Nodebench

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

RISK

Why draft_email_reply is rated Medium

This tool creates and structures new email content (draft composition), which is a reversible write operation. While it does not directly send emails (that is delegated to send_email), it generates email body content that modifies communication.

From the tool's definition Tool description states it 'builds a reply prompt' and returns 'a structured draft ready to review and send via send_email'. The draft_email_reply function creates new email content (write operation) that is intended to be sent.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs draft_email_reply safely

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

draft_email_reply Rate-limited

draft_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.
