Search for documents using full-text search across titles, names, descriptions, and body content
AI agents call sanity_search to retrieve information from Sanity MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves documents based on search criteria without modifying, creating, or deleting any data. It is a pure read operation with no side effects. The low severity reflects minimal blast radius even if an AI agent misuses the search capability, as the worst outcome would be information disclosure of already-stored content.
From the tool's definition Tool name 'sanity_search' and description states it performs 'Search for documents using full-text search across titles, names, descriptions, and body content' — a retrieval operation with no mutation or deletion capability.
