WHAT IT DOES

What nb_search_research does on Nodebench

AI agents call nb_search_research to retrieve information from Nodebench without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why nb_search_research is rated Low

This tool queries and retrieves existing research data without modifying, deleting, or executing operations. The search operation is a passive read-only action with minimal blast radius even if misused by an AI agent, as it only returns information rather than changing state or triggering external actions.

From the tool's definition Tool name contains 'search' and description states 'Search across research signals, briefings, and intelligence reports' — pure retrieval with no modification or execution capability.

RECOMMENDED RULE

The rule that runs nb_search_research safely

nb_search_research Allowed

nb_search_research is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Nodebench, apply this rule, and every nb_search_research call is checked against it from then on.
