Get information from all datasets in the Hub. Supports filtering by search terms, authors, tags, and more.
AI agents call hf_list_datasets 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 queries and retrieves metadata about datasets from the Hugging Face Hub. It performs filtering and listing operations only, with no side effects. The operations are read-only data retrieval, matching the Read category definition.
From the tool's definition Tool description states 'Get information from all datasets' and supports 'filtering by search terms, authors, tags' — pure retrieval operations with no modification or execution capability.
Attacks that exploit this kind of access
Get information from all datasets 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_datasets: 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_datasets 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_datasets 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_datasets. 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_datasets 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.
