tool_list_available_models
AI agents call tool_list_available_models to retrieve information from Open Google Image Generator MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Listing available models is a read-only operation that retrieves metadata about the system without modifying, deleting, or executing anything. There is no capability to generate, edit, or analyze content—merely to discover what models exist. This is the lowest-risk category.
From the tool's definition Tool name 'tool_list_available_models' clearly indicates listing or querying available models—a retrieval operation with no side effects. The empty description is uninformative, but the name strongly suggests a query/list action.
