SkyBuyFly MCP connector

SkyBuyFly compares duty-free prices for the same product across airport shops: hundreds of thousands of products at more than 80 airports, with prices collected from the airport shops' own websites (shops such as Heinemann, Avolta and Dubai Duty Free). This repository is the open source SkyBuyFly connector for AI assistants: a read-only Model Context Protocol server, its results widget and the client manifests (Claude plugin, Cursor plugin, Gemini CLI extension, MCP Registry entry). Connect it to your AI assistant and ask what a product costs at the airports you fly through; it can also confirm a price live on the airport shop's own page.

MCP server URL: https://skybuyfly.pitchai.net/mcp (Streamable HTTP, no sign-in, read-only tools)

SkyBuyFly compares prices; it does not sell anything and cannot reserve, order or pay. Links open SkyBuyFly's product and offer pages, which hand off to the airport shop's website. Tobacco and nicotine products are not included.

How it works

The connector is a thin facade over the public SkyBuyFly JSON API (https://skybuyfly.pitchai.net/api). It holds no credentials, keeps no state and calls only public read routes; prices, the catalogue and live price checks are served by SkyBuyFly's own (private) backend behind that API. Each tool validates its inputs, calls the API, shapes the answer into product cards and offers with their freshness (live-confirmed or stored, with its date), removes tobacco and nicotine products, and links only to skybuyfly.pitchai.net. The server adds its own rate limits, a cap on concurrent live checks and a short response cache, so it stays inside the API's own limits.

When your assistant calls a SkyBuyFly tool, it sends the tool's inputs (search text, product IDs, barcodes, airport codes, a currency) to the server, and the server answers with product information, prices and links. Nothing else is sent anywhere.

Install

The server needs no sign-in. Every option below connects to https://skybuyfly.pitchai.net/mcp directly; the plugin and extension installs in the Claude Code and Gemini CLI sections add the skill or context file of this repository as well.

ChatGPT

In ChatGPT on the web, open https://chatgpt.com/plugins, select the plus button and Add custom MCP server. Enter the name SkyBuyFly and, under Connection, the server URL https://skybuyfly.pitchai.net/mcp. Choose No authentication, review the risk warning and select I understand and want to continue, then select Create as a plugin. Install it from your plugins, then type @ in the prompt box and select SkyBuyFly. OpenAI's help centre lists custom MCP servers on ChatGPT on the web for Business and Enterprise/Edu, and for Pro with read and fetch permissions. On Business, an admin or owner adds them.

Claude (claude.ai, Claude Desktop)

Go to Customize > Connectors (https://claude.ai/customize/connectors), select + Add and then Add custom connector. Enter the name SkyBuyFly and the remote MCP server URL https://skybuyfly.pitchai.net/mcp, select Continue, choose No sign in and select Add. Turn it on in a chat with + > Connectors. Custom connectors are available on every Claude plan; on the Free plan you can add one. On Team and Enterprise plans, an Owner adds it under Organization settings > Connectors (Add, then Custom > Web), and members then select Connect under Customize > Connectors.

Claude Code

claude mcp add --transport http skybuyfly https://skybuyfly.pitchai.net/mcp

This adds the server to the current project; add --scope user before the name to use it in all your projects. To add the server together with the SkyBuyFly skill, install the plugin from this repository:

claude plugin marketplace add Pitch-A-I/skybuyfly-mcp
claude plugin install skybuyfly@skybuyfly

or, inside Claude Code, /plugin marketplace add Pitch-A-I/skybuyfly-mcp and /plugin install skybuyfly@skybuyfly.

VS Code

Install in VS Code (opens VS Code, which shows the server for review before you install it), or run MCP: Add Server from the Command Palette, choose HTTP and enter the server URL. To use a configuration file, add this to ~/.copilot/mcp-config.json:

{
  "mcpServers": {
    "skybuyfly": {
      "type": "http",
      "url": "https://skybuyfly.pitchai.net/mcp"
    }
  }
}

Cursor

Use the "Add to Cursor" button on https://skybuyfly.pitchai.net/mcp/docs, or paste this install link into your browser's address bar (Cursor asks before it installs the server):

cursor://anysphere.cursor-deeplink/mcp/install?name=SkyBuyFly&config=eyJ1cmwiOiJodHRwczovL3NreWJ1eWZseS5waXRjaGFpLm5ldC9tY3AifQ==

or add it to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json in a project:

{
  "mcpServers": {
    "skybuyfly": {
      "url": "https://skybuyfly.pitchai.net/mcp"
    }
  }
}

Gemini CLI

gemini mcp add --scope user --transport http skybuyfly https://skybuyfly.pitchai.net/mcp

Without --scope user, the server is added to the current project only. Or add this entry to ~/.gemini/settings.json:

{
  "mcpServers": {
    "skybuyfly": {
      "type": "http",
      "url": "https://skybuyfly.pitchai.net/mcp"
    }
  }
}

To add the server together with the SkyBuyFly context file, install the extension from this repository:

gemini extensions install https://github.com/Pitch-A-I/skybuyfly-mcp

Windsurf (Devin Desktop)

Windsurf is now part of Devin Desktop. In the Cascade MCP settings, select Add Server or open the MCP config file, and add:

{
  "mcpServers": {
    "skybuyfly": {
      "serverUrl": "https://skybuyfly.pitchai.net/mcp"
    }
  }
}

Then press the refresh button. On Enterprise plans, MCP has to be switched on in the settings first.

Mistral Vibe (Le Chat)

Le Chat is now Mistral Vibe (https://chat.mistral.ai). Open Connectors in the sidebar, select + Add Connector, open the Custom MCP Connector tab, enter the name SkyBuyFly and the server URL https://skybuyfly.pitchai.net/mcp, and select Connect. Vibe detects that no authentication is needed. Adding connectors is an administrator feature; on Free, Pro and Student plans the account owner is the administrator.

Perplexity

Open Plugins in the sidebar (or Customize > Connectors), choose Add custom > Connector > Add MCP connector, select Remote, enter the name SkyBuyFly and the MCP server URL https://skybuyfly.pitchai.net/mcp, set Authentication to None and Transport to Streamable HTTP, accept the notice and select Add. Then select the connector card to turn it on. Perplexity offers custom connectors on its Pro, Max and Enterprise plans.

Other MCP clients

Add a remote MCP server with the Streamable HTTP transport and the URL https://skybuyfly.pitchai.net/mcp. No authentication or headers are needed.

Tools

All tools are read-only. Every tool that shows prices takes an optional currency (ISO 4217, default USD).

Example prompts

• What does Chanel Coco Mademoiselle Eau de Parfum 100 ml cost at Vienna, Berlin and Vilnius duty free right now?

• Show the price history of Dior Sauvage Eau de Parfum 100 ml at airport duty-free shops.

• Which airport shops sell the product with barcode 3145891165203?

• Compare Lagavulin 16 at Copenhagen and Düsseldorf duty free in euros.

• Which London airports does SkyBuyFly compare?

Limits

• A live check usually takes 5 to 15 seconds (the tool waits at most 20 seconds).

• Up to 300 tool calls per minute per requesting address and 1,200 in total; live checks are limited to 20 new checks per minute and 4 at a time across all users. When a limit is reached, the tool says how long to wait, and stored prices stay available.

Run it yourself

You need Python 3.12 and uv.

uv sync
uv run python -m skybuyfly_mcp

The server listens on 0.0.0.0:8000 (set PORT to change it) and answers MCP at http://localhost:8000/mcp, its health at /mcp/health and its documentation pages at /mcp/docs. It calls the public SkyBuyFly API, so it needs no configuration; every setting is an environment variable with a default (src/skybuyfly_mcp/config.py):

The client address is read from X-Real-IP, so run the server behind a reverse proxy that sets that header. With Docker:

docker build -t skybuyfly-mcp .
docker run --rm --read-only --tmpfs /tmp -p 127.0.0.1:8000:8000 skybuyfly-mcp

A server you run yourself is subject to the SkyBuyFly API's own limits for your address; for everyday use, connect to https://skybuyfly.pitchai.net/mcp.

Tests

The connector's test suite (offline unit and end-to-end tests on recorded API answers, an integration suite against the live API, load tests and widget checks) is maintained in SkyBuyFly's private repository, together with the hosting setup. This repository mirrors the connector code of each release.
