Retrieves all folders from the client’s Google Drive. This is typically used as the first step to help the language model infer which specific folder to search in for a given document request.
AI agents call list-all-folders to retrieve information from Google Drive MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about folders from Google Drive without any side effects. It is a read-only operation that lists existing folder structure. The severity is low because the blast radius of misuse is minimal—an AI agent could only access folder names and structure already accessible to the authenticated user, posing no risk of data loss, modification, or financial impact.
From the tool's definition Tool name 'list-all-folders' and description 'Retrieves all folders' indicates a query operation with no modification or deletion of data.

Retrieves all folders from the client’s Google Drive. This is typically used as the first step to help the language model infer which specific folder to search in for a given document request. It is categorised as a Read tool in the Google Drive MCP MCP Server, which means it retrieves data without modifying state.
Register the Google Drive MCP server in PolicyLayer and add a rule for list-all-folders: 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 Google Drive MCP. Nothing to install.
list-all-folders is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list-all-folders 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 list-all-folders. 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.
list-all-folders is provided by the Google Drive MCP server (michaelpine25/googledrivemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
