Get detailed metadata about a file
AI agents call get_file_metadata to retrieve information from Enhanced MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves metadata (properties, attributes, timestamps, etc.) about files stored in Google Drive or similar services. It has no side effects, does not modify data, and does not trigger external actions.
From the tool's definition Tool name 'get_file_metadata' and description 'Get detailed metadata about a file' indicate a retrieval operation that queries file properties without modifying, deleting, or executing anything.
Attacks that exploit this kind of access
Get detailed metadata about a file. It is categorised as a Read tool in the Enhanced MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced MCP Server MCP server in PolicyLayer and add a rule for get_file_metadata: 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 Enhanced MCP Server. Nothing to install.
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.
Set action: deny in the PolicyLayer policy for get_file_metadata. 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.
get_file_metadata is provided by the Enhanced MCP Server MCP server (pbulbule13/mcpwithgoogle). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
