Search for files in Google Drive. Set rawQuery=true to pass a raw Google Drive API query supporting operators like modifiedTime, createdTime, mimeType, name contains, etc.
AI agents call search 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 or queries data from Google Drive without creating, modifying, deleting, or executing side effects. It is a pure Read operation that returns search results based on filter criteria. The severity is low because search operations have minimal blast radius—they only return information the user has already authorized access to view.
From the tool's definition Tool name is 'search' and description explicitly states it 'Search[es] for files in Google Drive' with no mention of modifying, deleting, or executing operations. The rawQuery parameter enables advanced filtering but remains a query operation.
Documented attack patterns abuse exactly the kind of access search 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 search:
{
"version": "1",
"default": "deny",
"tools": {
"search": {}
}
}search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for files in Google Drive. Set rawQuery=true to pass a raw Google Drive API query supporting operators like modifiedTime, createdTime, mimeType, name contains, etc. 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 search: 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.
search 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 search 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 search. 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.
search 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.
