What search_flights does on Nitrostack
AI agents call search_flights to retrieve information from Nitrostack without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why search_flights is rated Low
This tool queries a flight database and returns matching results without creating, modifying, deleting, or executing operations. It is a standard informational lookup that does not change system state or commit any obligations. The low severity reflects minimal blast radius if misused—an agent could generate excessive queries but cannot cause financial transactions or data destruction.
From the tool's definition Tool description states it 'Search for flight offers' and 'Returns available flight options with pricing and details.' The verb 'search' and the read-only nature of returning flight information indicates data retrieval with no side effects.

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