AI agents call mysql_grants_for_entities to retrieve information from Mcp Windows without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation to view existing database grants and permissions. It has no side effects, does not execute code, and does not modify or delete any data. While the information retrieved could be sensitive (revealing user permissions), the tool itself is purely informational with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description states 'Show grants assigned to roles and users' — a query operation that retrieves and displays existing permission/grant information without modifying, executing, or deleting data.
