create_draft · Enhanced MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_draft does on Enhanced MCP Server

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

WHY IT NEEDS A POLICY

Why create_draft needs a policy

Creating a draft email is a reversible modification operation—the draft can be edited, deleted, or discarded before sending. It does not execute external actions, delete data, or move money. While drafts could theoretically be manipulated to send unintended messages, the act of draft creation itself is a benign write operation.

From the tool's definition Tool name 'create_draft' and description 'Create a draft email' indicate the tool creates email content as a draft (not yet sent). The Gmail API context and sibling tools (add_email_template, add_contact) confirm this is a write operation on email data.

create_draft Rate-limited

create_draft 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.
