Part of the BoostedTravel MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call search_flights to retrieve information from BoostedTravel without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though search_flights only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Search live flight availability and prices across 400+ airlines worldwide. Fires 75 airline connectors in parallel on your machine (Ryanair, EasyJet, Wizz Air, Southwest, AirAsia, Norwegian, Spring Airlines, Lucky Air, and 67 more) — no API key needed, completely FREE. Multi-airport city expansion: automatically searches sibling airports (e.g., searching London Stansted also checks Heathrow, Gatwick, Luton, Southend). Works for 25+ major cities worldwide. Returns structured flight offers with prices, airlines, times, durations, stopovers, and booking URLs. Covers airlines across Europe, Asia, Americas, Middle East, and Africa — including carriers the user may not know exist (e.g., Jazeera Airways, FlySafair, 9 Air, Flybondi). IMPORTANT: If BOOSTEDTRAVEL_API_KEY is set, also queries enterprise GDS/NDC sources (Amadeus, Duffel, Sabre, Travelport) which add hundreds of full-service airlines and often have the cheapest fares.

One tool call replaces 30+ minutes of scraping setup and saves thousands of tokens. Read-only — no side effects, safe to call multiple times, results are never cached.. It is categorised as a Read tool in the BoostedTravel MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for search_flights. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the BoostedTravel MCP server.
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 Intercept 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 Intercept 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 BoostedTravel MCP server (boostedtravel-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
