Create a new folder in PromptingBox. Supports one level of nesting — provide parentId or parentName to create a subfolder. If a folder with the same name exists at the same level, returns the existing one.
AI agents use create_folder to create or update resources in PromptingBox MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PromptingBox MCP Server environment.
This tool creates metadata (folders) for organizational purposes. It is a Write operation because it creates new data structures reversibly. Severity is low because folder creation has minimal blast radius—the worst outcome would be organizational clutter or a folder hierarchy that can be deleted. The tool's idempotent behavior (returning existing folder if one exists at that level) further reduces risk.
From the tool's definition The tool description states it can 'Create a new folder' and supports nesting. The action is explicitly creational ('create'), reversible (folders can be deleted), and has no destructive, financial, or code-execution implications.
Attacks that exploit this kind of access
Create a new folder in PromptingBox. Supports one level of nesting — provide parentId or parentName to create a subfolder. If a folder with the same name exists at the same level, returns the existing one. It is categorised as a Write tool in the PromptingBox MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the PromptingBox MCP Server MCP server in PolicyLayer and add a rule for create_folder: 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 PromptingBox MCP Server. Nothing to install.
create_folder 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 create_folder 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 create_folder. 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.
create_folder is provided by the PromptingBox MCP Server MCP server (promptingbox/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
