Get information from all models in the Hub. Supports filtering by search terms, authors, tags, and more.
AI agents call hf_list_models to retrieve information from Hugging Face Hub MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and filters metadata about machine learning models without creating, modifying, deleting, or executing any operations. It is purely a query/search operation with no side effects, matching the 'Read' category definition. The filtering and search capabilities do not change this classification. Blast radius is minimal as the tool only returns informational data.
From the tool's definition Tool name 'hf_list_models' and description 'Get information from all models in the Hub' indicates retrieval/querying operation with 'Supports filtering by search terms, authors, tags' - no modification or execution of external operations.
Attacks that exploit this kind of access
Get information from all models in the Hub. Supports filtering by search terms, authors, tags, and more. It is categorised as a Read tool in the Hugging Face Hub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Hugging Face Hub MCP Server MCP server in PolicyLayer and add a rule for hf_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 Hugging Face Hub MCP Server. Nothing to install.
hf_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 hf_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 hf_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.
hf_list_models is provided by the Hugging Face Hub MCP Server MCP server (michaelwaves/hf-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
