List all models
AI agents call list_models to retrieve information from Rockfish MCP Server 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 that queries and returns information about models in the ML platform. There are no state changes, no code execution, and no data modifications. The blast radius of misuse is minimal—unauthorized listing of models could expose organizational information but cannot directly damage data or systems. This is a classic Read category tool.
From the tool's definition Tool name 'list_models' and description 'List all models' indicate a retrieval operation with no side effects. This is a query/list action that retrieves information about existing models without modifying, creating, or deleting anything.
Attacks that exploit this kind of access
List all models. It is categorised as a Read tool in the Rockfish MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Rockfish MCP Server 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 Rockfish MCP Server. 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 Rockfish MCP Server MCP server (wolfdancer/rockfish-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
