list_models
AI agents call list_models to retrieve information from Model Radar without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a list of models without modifying, executing, or deleting anything. It is a query/list operation typical of Read category tools. No description provided, but the name, context (model discovery/ranking server), and sibling tools (get_fastest, benchmark) strongly indicate it simply enumerates available models.
From the tool's definition Tool named 'list_models' with sibling tools like 'get_fastest', 'benchmark', and 'compare' on a server that 'ranks [models] by latency' and 'helps AI agents pick the fastest available model'.
Attacks that exploit this kind of access
list_models. It is categorised as a Read tool in the Model Radar MCP Server, which means it retrieves data without modifying state.
Register the Model Radar 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 Model Radar. 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 Model Radar MCP server (srclight/model-radar). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
