Retrieves all files within a specified folder in the client’s Google Drive. This is typically used after selecting the correct folder to locate a specific document requested by the user.
AI agents call list-files-in-folder 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 performs a read-only query of folder contents without creating, modifying, or deleting any data. It has minimal blast radius—an AI agent misuse would only expose existing file metadata to which the user has already granted access via OAuth. The description contains no indication of execution, modification, or destructive capabilities.
From the tool's definition Tool "retrieves all files within a specified folder" with no modification capability. Returns file listing data only.

Register the Google Drive MCP server in PolicyLayer and add a rule for list-files-in-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 Google Drive MCP. Nothing to install.
list-files-in-folder 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-files-in-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 list-files-in-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.
list-files-in-folder 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.
