For your AI
Ask your AI for our fares
Add a2bflight to the AI you already use. It can then look up the cheapest fares we hold on thousands of routes, and every fare it shows links back here.
How it works
- Connect a2bflight to your AI once: one click for Claude, a minute for ChatGPT or Gemini.
- Ask about flights in your own words, the way you would ask a friend.
- Your AI checks our fares and answers with real prices, the date each was seen, and a link to book.
Server address
https://mcp.a2bflight.com/mcpClaude
One click opens Claude with a2bflight filled in; confirm to add it. Works on every plan — the free plan allows one custom connector.
ChatGPT
ChatGPT has no install link yet. On the web, turn on “Developer mode” in Settings, create an app with the server address above and no authentication, then pick it from the + menu in a chat. Plus, Pro, Business, Enterprise and Edu plans.
Gemini
In the Gemini app, open Settings → Connected Apps → Custom apps → Add a custom app and paste the server address. Personal accounts in the US only for now; anywhere else, use Gemini CLI below.
Why use it
- Real prices, not guesses. On its own an AI can only guess what a flight costs; connected, it quotes the cheapest fares we have actually seen.
- The whole trip in one chat. Ask about flights in the same conversation where you plan the rest — dates, budget, where to stay.
- Free, with nothing to sign up for. No account and no new app.
What is MCP?
MCP (Model Context Protocol) is a common way for AI assistants to connect to outside services — a little like adding an app to your phone. Once a2bflight is connected, your AI asks us for fares whenever your question needs them, and only then.
Coding tools
One click installs it in these apps; the terminal tools take one command.
- Claude Code
claude mcp add --transport http --scope user a2bflight https://mcp.a2bflight.com/mcp- Gemini CLI
gemini mcp add --transport http --scope user a2bflight https://mcp.a2bflight.com/mcp

- “Where can I fly from Chicago for under $150?”
Good to know
Prices are the cheapest fares we have seen — one-way, one adult, economy — each with the date it was seen. The seller's page shows today's price before you book.
Your AI asks us about routes and dates only: there is no account, and nothing that identifies you reaches us. For answers shaped by your own searches on this site, ask our assistant.
