List available MuAPI model categories
AI agents call list_models to retrieve information from MuAPI Claude Code MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of model categories without creating, modifying, deleting, or executing any operations. It is a pure information retrieval function, fitting the Read category. Severity is low because misuse poses minimal risk: listing available models cannot compromise data, trigger unwanted generation, or cause financial harm.
From the tool's definition Tool name is 'list_models' and description states 'List available MuAPI model categories' — a read-only operation that retrieves metadata about available models with no side effects.

List available MuAPI model categories. It is categorised as a Read tool in the MuAPI Claude Code MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MuAPI Claude Code 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 MuAPI Claude Code 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 MuAPI Claude Code MCP Server MCP server (SamurAIGPT/muapi-claude-code). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
