WHAT IT DOES

What createDocument does on Nodebench

AI agents use createDocument 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 createDocument is rated Medium

This tool creates new documents, which is a reversible write operation. It does not delete data (would be Destructive), execute arbitrary code (would be Execute), or move money (would be Financial). Severity is medium because uncontrolled document creation could spam storage or clutter systems, but the operation is reversible through deletion.

From the tool's definition Tool name 'createDocument' and description 'Create a new rich-text document' explicitly indicate creation of new data.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

createDocument Rate-limited

createDocument 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.

LIMIT THIS TOOL → Instant setup, no code required.

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

What risk level is createDocument? +

Can I rate-limit createDocument? +
