AI agents call drive_listFiles to retrieve information from Google MCP Remote without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists data from Google Drive without any side effects. It is a read-only operation that poses minimal risk even if misused by an AI agent, as it cannot modify, delete, or execute actions. The primary risk is unauthorized information disclosure, which is inherent to any authenticated read access but does not elevate severity beyond low for a listing operation.
From the tool's definition Tool name is 'drive_listFiles' and description states 'List files from Google Drive' — a query operation with no modification or deletion of data.

PolicyLayer is an MCP gateway — it sits between your AI agents and Google MCP Remote, and nothing reaches the server without passing your rules. This is the rule we recommend for drive_listFiles:
{
"version": "1",
"default": "deny",
"tools": {
"drive_listFiles": {}
}
}drive_listFiles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

drive_listFiles 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 drive_listFiles 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 drive_listFiles. 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.
drive_listFiles is provided by the Google MCP Remote MCP server (vakharwalad23/google-mcp-remote). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Google MCP Remote, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
