Creates a new folder node in a library or in the browser bookmarks. NOT for the main tab tree (the main tree uses windows + groups, not folders). Required scope:
AI agents use create_folder to create or update resources in Pinako AI Bridge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pinako AI Bridge environment.
This tool creates new data structures (folders) in persistent storage (libraries or browser bookmarks), which is a reversible write operation. It modifies state but does not irreversibly delete data (ruling out Destructive) and does not execute arbitrary code or trigger external operations (ruling out Execute). It is not financial in nature.
From the tool's definition Creates a new folder node in a library or in the browser bookmarks. The tool performs a state-changing operation that creates a persistent data structure (a folder) that can be modified or deleted later.
Attacks that exploit this kind of access
Creates a new folder node in a library or in the browser bookmarks. NOT for the main tab tree (the main tree uses windows + groups, not folders). Required scope:. It is categorised as a Write tool in the Pinako AI Bridge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Pinako AI Bridge 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 Pinako AI Bridge. 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 Pinako AI Bridge MCP server (teleomorph/pinako-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
