What it can do
Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
get_dealOne 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 na
search_dealsSearch 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 pag
watch_routeThe Sparkflights page that saves a fare watch for a route: url opens the watch form with both cities and the cabin filled in. A watch covers every airport of both cities. Saving it needs a free Sparkflights account.

Common questions
Is Sparkflights safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.1.1) reached the registry today.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

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/searchThe 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 asNew 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.
Add it to your client
Claude (claude.ai or Claude Desktop): Settings → Connectors → Add custom connector, then paste the URL above.
Claude Code:
claude mcp add --transport http sparkflights https://www.sparkflights.com/mcp/searchCursor (~/.cursor/mcp.json):
{"mcpServers": { "sparkflights": { "url": "https://www.sparkflights.com/mcp/search" } } }
VS Code (.vscode/mcp.json):
{"servers": { "sparkflights": { "type": "http", "url": "https://www.sparkflights.com/mcp/search" } } }
ChatGPT: turn on developer mode, then add a custom MCP server with the URL above.
Other clients: mcp.json has the standard mcpServers entry.
