Count documents in a collection matching a query
AI agents call count_documents 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 only retrieves aggregate information (a count) from a collection without modifying, creating, deleting, or executing arbitrary operations. It falls squarely into the Read category. Severity is low because misuse by an AI agent would only expose the existence and volume of documents, with no destructive or system-compromising potential.
From the tool's definition The tool 'count_documents' performs a read-only operation that retrieves a count of documents matching a query criteria.

Register the Google Workspace MCP Server MCP server in PolicyLayer and add a rule for count_documents: 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.
count_documents 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 count_documents 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 count_documents. 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.
count_documents is provided by the Google Workspace MCP Server MCP server (pbulbule13/google-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
