List children of a Drive folder by folder ID.
AI agents call drive_list to retrieve information from Hermes Google without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves data (folder contents) with no side effects. It does not create, modify, delete, or execute operations. The verb 'list' is a canonical read operation. Low severity because the blast radius of misuse is limited to information disclosure of folder structure, assuming permissions are properly scoped.
From the tool's definition Tool name 'drive_list' and description 'List children of a Drive folder by folder ID' indicate a read-only operation that retrieves directory contents without modification.

Register the Hermes Google MCP server in PolicyLayer and add a rule for drive_list: 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 Hermes Google. Nothing to install.
drive_list 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_list 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_list. 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_list is provided by the Hermes Google MCP server (jimmy-larsson/hermes-google). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
