AI agents call hunter_search to retrieve information from Hunter without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description, the naming context and sibling tools (batch_task_create, batch_task_progress, batch_task_result_download) indicate this is a search/query tool that retrieves asset data from the Hunter platform. The absence of action verbs like 'create', 'delete', or 'execute' and the placement alongside batch query tools strongly suggests read-only asset search.
From the tool's definition Tool name 'hunter_search' on a 'network asset mapping platform' with sibling tools for batch queries and export tasks suggests data retrieval functionality.

hunter_search 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 hunter_search 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 hunter_search. 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.
