What createFolder does on Nodebench
AI agents use createFolder 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.
Why createFolder is rated Medium
Creating a folder is a reversible write operation. It modifies the document organization system by adding a new container, but this action can be undone by deleting the folder. There is no data destruction, code execution, or financial impact. Severity is low because creating a folder has minimal blast radius—at worst, it creates unused organizational clutter that can be easily removed.
From the tool's definition Tool name is 'createFolder' and description states 'Create a new folder for organizing documents.' The verb 'Create' indicates the tool creates new data (a folder structure).
Attacks that exploit this kind of access
The rule that runs createFolder 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 createFolder, this is the rule to start with:
createFolder 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 Nodebench, apply this rule, and every createFolder call is checked against it from then on.
Questions about createFolder
Create a new folder for organizing documents. It is categorised as a Write tool in the Nodebench MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Nodebench MCP server in PolicyLayer and add a rule for createFolder: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Nodebench. Nothing to install.
createFolder is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the createFolder rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for createFolder. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
createFolder is provided by the Nodebench MCP server (nodebench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
