Searches across all files in Google Drive by name, content, or type. More powerful than type-specific search tools.
AI agents call searchDrive 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.
searchDrive retrieves information from Google Drive without creating, modifying, deleting, or executing any operations. It is a passive data retrieval tool with no side effects or ability to alter system state. The blast radius of misuse is minimal—an attacker could enumerate files but cannot access their contents, modify them, or cause damage through this tool alone.
From the tool's definition Tool description states it "Searches across all files in Google Drive by name, content, or type" with no mention of modifying, deleting, or executing actions. The verb "searches" and "search" in the name clearly indicate a read-only query operation.
Attacks that exploit this kind of access
Searches across all files in Google Drive by name, content, or type. More powerful than type-specific search tools. It is categorised as a Read tool in the Google Workspace MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Google Workspace MCP Server MCP server in PolicyLayer and add a rule for searchDrive: 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 Workspace MCP Server. Nothing to install.
searchDrive 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 searchDrive 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 searchDrive. 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.
searchDrive is provided by the Google Workspace MCP Server MCP server (pm990320/google-workspace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
