WHAT IT DOES

What create_draft does on Ncp

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

RISK

Why create_draft is rated Medium

Creating an email draft is a reversible write operation that modifies state (adds a new draft to the user's email account) but does not send communication or trigger external side effects. The draft exists only until explicitly sent or deleted, making it a Write rather than Execute or Destructive action.

From the tool's definition Tool name 'create_draft' and description 'Create email draft' indicate the tool creates a new, unsaved email document that can be modified or discarded without sending.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_draft safely

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

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.

The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every create_draft call is checked against it from then on.
