Flightoracle

What flightoracle MCP server does

The flightoracle MCP server gives MCP-compatible agents access to flight search and comparison functions backed by Google Flights. Its eight tools cover common planning tasks: searching round-trip or one-way routes, finding low prices across a month, pricing multi-city trips, comparing airlines, checking weekly fare patterns, finding airport codes, and checking service health.

The server is intended for travel-planning workflows where an agent needs structured flight information rather than a general web search. It can help an agent investigate a specific route, compare alternatives, or narrow a trip by price and itinerary structure.

How it works

Connections use the live remote MCP endpoint at https://tooloracle.io/flight/mcp/. Once connected, the client can discover and call the exposed tools through MCP.

The primary search tool supports round-trip and one-way flight searches between airports. Separate tools handle one-way searches, month-wide cheapest-flight discovery, and multi-city routes with two or more legs. Price-calendar results are organized by week for a route, while route comparison groups prices by airline. The airport tool helps convert a city into IATA airport codes and can return nearby airports. health_check reports server status, API connectivity, and supported features.

Setup and configuration

Configure the remote server in a client using the following structure:

{
  "mcpServers": {
    "flightoracle": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://tooloracle.io/flight/mcp/"]
    }
  }
}

The service is available on a free tier with a limit of 100 calls per day. Pro and Enterprise tiers are also listed, at 10,000 calls per day for €29 per month and unlimited usage at a custom price, respectively.

Tools and capabilities

• flight_search: Search round-trip or one-way flights between airports.
• cheapest_flights: Find price-sorted flight options across a full month.
• one_way_search: Search one-way flights with the available filters.
• multi_city: Price routes with two or more legs and return per-leg and total pricing.
• price_calendar: Compare weekly prices for a route to find a cheaper week.
• route_compare: Compare route prices by airline, including stops and the cheapest option per airline.
• airport_hub: Find IATA codes, nearby airports, and common airport codes for a city.
• health_check: Check server status, API connectivity, and supported features.

Limitations and notes

The free plan is rate-limited to 100 calls per day, so repeated agent searches may require a higher tier. The documentation describes search and pricing information but does not specify booking, ticket purchase, reservation changes, or fare guarantees. The flightoracle MCP server should therefore be treated as a flight research and comparison interface, not as a booking system.
