List available image generation models from all enabled providers.
AI agents call list_models to retrieve information from Universal Image without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs read-only retrieval of metadata about available models across providers. It does not create, modify, delete, execute code, or commit financial transactions. This is a straightforward enumeration endpoint that helps users discover what models are available.
From the tool's definition Tool description states 'List available image generation models from all enabled providers' - a pure query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List available image generation models from all enabled providers. It is categorised as a Read tool in the Universal Image MCP Server, which means it retrieves data without modifying state.
Register the Universal Image 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 Universal Image. 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 Universal Image MCP server (manu-mishra/universal-image-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
