Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Variflight MCP for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "variflight": { "command": "npx", "args": [ "-y", "@variflight-ai/variflight-mcp" ], "env": { "VARIFLIGHT_API_KEY": "your-value" } } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) For VARIFLIGHT_API_KEY, leave "your-value" in place and tell me to paste the real value myself into the file or the app’s field. Never ask me to type a key in chat. 5) Do what we agreed, then check that the Variflight MCP tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

Common questions

Is Variflight MCP safe?

It passed 2 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?

You need to fill in: VARIFLIGHT_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 36 days ago, and the latest version (1.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

Variflight MCP Server

A Model Context Protocol (MCP) server implementation for VariFlight flight information services. This server provides various tools to query flight information, weather data, and flight comfort metrics.

This package is the stdio distribution of VariFlight Aviation MCP on the VariFlight AI Open Platform. Full documentation, including client setup, tool reference and pricing: ai.variflight.com/docs/aviation (中文).

Variflight API Key

To use the Variflight MCP server, you need to have a Variflight API key. Sign up at ai.variflight.com and create one in the console; new accounts receive ¥50 in trial credits.

Remote server

The same tools are available as a remote MCP server over streamable HTTP, with no local process required:

claude mcp add --transport http variflight-aviation https://ai.variflight.com/servers/aviation/mcp \

--header "X-API-Key: YOUR_API_KEY"

Clients that support OAuth 2.1 can add https://ai.variflight.com/servers/aviation/mcp without a key and sign in when prompted.

Installation

"mcpServers": { "variflight": { "command": "npx", "args": [ "-y", "@variflight-ai/variflight-mcp" ], "env": { "VARIFLIGHT_API_KEY": "your_api_key_here" } } } }

Available Tools

1. Search Flights by Departure and Arrival

Search direct flights by city or airport code on a specific date. Use city codes like BJS or exact airport codes like PEK, but do not mix city and airport codes for the same side:

searchFlightsByDepArr({

dep: "PEK", // Beijing arr: "SHA", // Shanghai date: "2024-03-20" })

2. Search Flights by Number

Search a specific flight by flight number and date:

searchFlightsByNumber({

fnum: "MU2157", date: "2024-03-20" })

3. Get Flight Transfer Information

Search connecting flight options between departure and arrival cities:

getFlightTransferInfo({

depcity: "BJS", arrcity: "LAX", depdate: "2024-03-20" })

searchFlightsByDepArr and getFlightTransferInfo also accept optional paging parameters. Busy routes can return dozens of results with many fields each, so use these to keep responses small:

limit: maximum number of results to return
offset: number of results to skip; pass next_offset from the previous response to get the next page. Each page is a separate billed call.
detail: "summary" returns only the core fields of each result; "full" (the default) returns every field

When any of them is set, the response also includes total, offset, returned and, if more results exist, next_offset. Without them, the response is unchanged.

searchFlightsByDepArr({

depcity: "BJS", arrcity: "SHA", date: "2024-03-20", limit: 20, detail: "summary" })

4. Flight Happiness Index

Get comfort-focused details for a known flight, such as punctuality, aircraft type, cabin configuration, meals, and entertainment:

flightHappinessIndex({

fnum: "MU2157", date: "2024-03-20" })

5. Real-time Aircraft Location

Track realtime flight location using the aircraft registration number, also called tail number:

getRealtimeLocationByAnum({

anum: "B2021" })

6. Airport Weather Forecast

Get the 3-day airport weather forecast:

getFutureWeatherByAirport({

airport: "PEK" })

7. Search Flight Itineraries

Get a natural-language summary with recommended flight options, overall lowest price, shortest duration, and several suggested itineraries:

searchFlightItineraries({

depCityCode: "BJS", // Beijing arrCityCode: "SHA", // Shanghai depDate: "2025-04-20" })

8. Get Flight Prices by Cities

Get structured raw sale-flight data between two cities, with each flight returning cabin-level prices:

getFlightPriceByCities({

dep_city: "BJS", // Beijing arr_city: "SHA", // Shanghai dep_date: "2026-04-20" })
