WHAT IT DOES

What batch_search_google does on Crawl4AI MCP Server

AI agents call batch_search_google to retrieve information from Crawl4AI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why batch_search_google needs a policy

This tool performs batch Google searches, which retrieves search results from an external service. No side effects, modifications, or external actions are triggered—it only reads and returns search data. This aligns with the Read category. Severity is low because search queries have minimal blast radius; an AI agent querying Google poses no direct harm to systems or data.

From the tool's definition Tool name 'batch_search_google' combined with sibling tool 'get_search_genres' and server's 'Google search integration' capability indicates querying external search engine. Empty description weakens confidence.
