About Sparkflights

Sparkflights is a hosted MCP server for finding verified flight fares by route, month, cabin, region, and price. It is for travelers and MCP clients seeking fare details and booking links; results reflect fares Sparkflights has verified, not a live search.

Key features

  1. 01Search verified fares by route and month
  2. 02Filter by cabin, region, and price
  3. 03Rank results by cost per mile
  4. 04Retrieve itinerary, flights, and date prices
  5. 05Open fare and route pages

Use cases

  1. 01Find fares between cities for a chosen month
  2. 02Search for cabin-specific fares below a price limit
  3. 03Inspect a result's flights and listed dates

MCP support

Sparkflights exposes two read-only tools through a hosted Streamable HTTP MCP server: `search_deals` and `get_deal`. MCP clients can search verified fares and retrieve details, with results linking to fare pages for booking.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details

From the project README

Sparkflights MCP server

Search flight fares that Sparkflights has found and verified, from Claude, ChatGPT, Cursor, VS Code or any other MCP client.

https://www.sparkflights.com/mcp/search

The server is hosted. There is nothing to install, no account and no API key. It uses streamable HTTP.

Tools

Both tools only read data.

  • search_deals finds verified fares by origin and destination (an airport code such as JFK, or a city such as New York), departure month, cabin, region and maximum price. Results are ranked by cost per mile.
  • get_deal returns one fare's itinerary, flights and the date pairs its fare page lists, with their prices.

Each result links to its Sparkflights fare page, where you book it, and to its route page, where you can follow the route for new fares.

Sparkflights is not a live fare search. An empty result means no verified fare matches right now, not that no flights exist. Sparkflights does not sell tickets or take payments.

Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "sparkflights": {
      "url": "https://www.sparkflights.com/mcp/search"
    }
  }
}

VS Code (.vscode/mcp.json):

{

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
