List supported OpenAI image models with their capabilities (sizes, qualities, edit/variation support, etc.). Use this before calling generate_image or edit_image to check which options a model accepts.
AI agents call list_models to retrieve information from Openai Images without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about available image models and their supported parameters. It has no side effects, does not execute operations, does not modify data, and does not create financial obligations. It is a read-only query operation for informational purposes.
From the tool's definition Tool name 'list_models' and description explicitly states it lists supported models and their capabilities with no mention of modification, deletion, or execution of operations. It is a pure information retrieval function (check which options a model accepts).

List supported OpenAI image models with their capabilities (sizes, qualities, edit/variation support, etc.). Use this before calling generate_image or edit_image to check which options a model accepts. It is categorised as a Read tool in the Openai Images MCP Server, which means it retrieves data without modifying state.
Register the Openai Images MCP server in PolicyLayer and add a rule for list_models: 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 Openai Images. Nothing to install.
list_models 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 list_models 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 list_models. 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.
list_models is provided by the Openai Images MCP server (sam-david/openai-images-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
