Search flight fares by city, month, cabin and price, and watch a route for new deals.
Searches flight fares Sparkflights has already found, shows one fare's dates and flights, and links a route watch form.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.Sparkflights-com%2Fsparkflights/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Search the flight fares Sparkflights has found, from Claude, ChatGPT, Cursor, VS Code or any other MCP client, and watch a route for new ones.
The server is hosted — nothing to install. Searching needs no account; to save a route watch you sign in with Google, Microsoft or email. It uses streamable HTTP.
search_deals and get_deal only read fares. watch_route saves a watch to your account.
search_deals finds 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.watch_route saves a fare watch for the route — every airport of both cities, in the cabin you name. The first time you save one your client signs you in; new deals on the route then come by email and browser notification.Each fare links to its Sparkflights fare page, where you book it.
Sparkflights is not a live fare search. An empty result means no fare matches right now, not that no flights exist. Sparkflights does not sell tickets or take payments.
Claude (claude.ai or Claude Desktop): Settings → Connectors → Add custom connector, then paste the URL above.
Claude Code:
Cursor (~/.cursor/mcp.json):
VS Code (.vscode/mcp.json):
ChatGPT: turn on developer mode, then add a custom MCP server with the URL above.
Other clients: mcp.json has the standard mcpServers entry.
server.json is published to the MCP Registry by .github/workflows/publish-mcp.yml when a v* tag is pushed. Bump version in server.json before tagging.

Get a flight deal
One Sparkflights fare by the numeric id from search_deals: its itinerary, the price text of its fare page, its outbound and return flights, the date pairs its fare page lists with their prices, and its url, route_url and feed_url. A fare that is no longer live returns an error naming its route page.
idrequiredSearch flight deals
Search flight fares Sparkflights has already found, ranked by cost per mile against each market's limit. Not a live fare search: an empty result means no current fare matches. Each deal has the price text of its Sparkflights fare page; url, the fare page; route_url, the route page, which lists the route's live fares and price history; and feed_url, the route's JSON feed of new fares. A search naming an origin or destination also returns fares when its deals are fewer than limit: the cheapest current fares for that place, as Google's flight explorer showed them, each with its price, dates, airline, seen_at (when it was seen) and route_url, its route page. A fare has no id or fare page yet.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
