Search for flight offers between two airports. Returns flight options with prices, airlines, and schedules.
AI agents call search_flights to retrieve information from Travel 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 flight data from aggregated APIs (Amadeus, AviationStack) and returns results without side effects. It performs information retrieval only, matching the Read category. The severity is low because misuse causes no data loss, financial harm, or system compromise—only potentially irrelevant search results.
From the tool's definition Tool 'search_flights' description states it 'Returns flight options with prices, airlines, and schedules' — a retrieval operation. The server description emphasizes 'search for flights' and 'retrieve airport information' as core read capabilities.

Register the Travel MCP Server MCP server in PolicyLayer and add a rule for search_flights: 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 Travel MCP Server. Nothing to install.
search_flights 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 search_flights 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 search_flights. 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.
search_flights is provided by the Travel MCP Server MCP server (lev-corrupted/travel-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
