Get detailed metadata about a file
AI agents call get_file_metadata to retrieve information from Google Workspace 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 file metadata (properties, attributes, timestamps, etc.) from Google Workspace/Drive without altering data, executing operations, or triggering external side effects. It is a straightforward read operation with minimal blast radius—the worst case being information disclosure of file properties already accessible to the authenticated user.
From the tool's definition Tool name is 'get_file_metadata' and description states it 'Get detailed metadata about a file' — a retrieval operation with no modification, deletion, or execution of code.

get_file_metadata 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 get_file_metadata 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.
