List configured/requested scopes and currently granted scopes
AI agents call authListScopes to retrieve information from Google Drive MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves authentication and authorization metadata (scopes) from the Google Drive integration. It performs no mutations, creates no side effects, and only displays what scopes have been configured and granted. This is a pure Read operation with minimal security risk—the information returned is about permissions themselves rather than sensitive user data or files.
From the tool's definition Tool name 'authListScopes' and description 'List configured/requested scopes and currently granted scopes' indicate a query/retrieval operation that returns configuration and permission state without modifying any data.
Documented attack patterns abuse exactly the kind of access authListScopes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Google Drive MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for authListScopes:
{
"version": "1",
"default": "deny",
"tools": {
"authListScopes": {}
}
}authListScopes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List configured/requested scopes and currently granted scopes. It is categorised as a Read tool in the Google Drive MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Google Drive MCP Server MCP server in PolicyLayer and add a rule for authListScopes: 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 Server. Nothing to install.
authListScopes 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 authListScopes 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 authListScopes. 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.
authListScopes is provided by the Google Drive MCP Server MCP server (piotr-agier/google-drive-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
