Airport Lounge List MCP Server

A hosted Model Context Protocol server that lets an AI assistant answer the question every frequent flyer actually has: which lounge can I get into here, with the cards I already hold?

Search lounges at any airport, check access by credit card, membership, airline status or ticket class, compare networks like Priority Pass, and — once you sign in — log visits, write reviews and keep a wishlist.

https://mcp.airportloungelist.com/mcp

There is nothing to install and no API key to copy. Add the URL to your MCP client and the tools appear. The eight lounge-data tools work immediately, with no account.

Install

Claude Code

claude mcp add airport-lounge-list --transport http https://mcp.airportloungelist.com/mcp

Claude Desktop, Cursor, Windsurf, VS Code

{
  "mcpServers": {
    "airport-lounge-list": { "url": "https://mcp.airportloungelist.com/mcp" }
  }
}

Gemini CLI — this repository is a Gemini CLI extension:

gemini extensions install https://github.com/Airport-Lounge-List/mcp-server

Clients without native remote-server support can bridge with mcp-remote:

{
  "mcpServers": {
    "airport-lounge-list": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.airportloungelist.com/mcp"]
    }
  }
}

Tools

21 tools — see TOOLS.md for the full table with titles and descriptions.

Eight are public and need no account: search_lounges, get_airport_lounges, get_lounge_details, find_lounges_by_access, list_access_methods, list_networks, get_network_lounges, discover_more_flight_tools.

The other thirteen read or change your own reviews, visits and wishlist, and need OAuth.

Every tool declares MCP title and annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint), so a client can tell a read from a write before it calls anything.

Transport and authentication

Streamable HTTP. SSE is not used.

Public tools need no token and are rate limited per IP address. Signing in lifts the limit.

Tools that touch your own data use OAuth 2.1 with PKCE and RFC 7591 dynamic client registration, so a compliant client registers itself and opens a browser for consent — no keys to paste. Scopes are read and write; the eight mutating tools require write.

Calling a protected tool without a token returns 401 with a WWW-Authenticate header pointing at the RFC 9728 protected-resource document, which is how your client discovers the authorization server. initialize, tools/list and the public tools never return that challenge.

Discovery documents

• /.well-known/mcp.json — server card with the full tool list
• /.well-known/oauth-protected-resource/mcp — RFC 9728
• /.well-known/oauth-authorization-server — RFC 8414
• /auth.md — the OAuth flow written for an agent to follow
• /.well-known/agent-card.json — A2A agent card

Related servers

Same team, same install pattern — each is a separate remote MCP server:

Server	Answers	Endpoint
Award Travel Finder	Can I redeem points for this flight?	https://mcp.awardtravelfinder.com/mcp
FlightSeatMap	Which seat should I pick?	https://mcp.flightseatmap.com/mcp
FlightQueue	How long is security right now?	https://mcp.flightqueue.com/mcp

The discover_more_flight_tools tool returns the same list with install snippets.

Network access and credentials

The plugin declares exactly one network endpoint, https://mcp.airportloungelist.com/mcp, configured in .mcp.json. It ships no hooks, no scripts and no executable code — there is nothing to run locally, so nothing reads your filesystem, environment or shell.

No credentials are needed for the eight public tools. The thirteen account tools use OAuth 2.1: your client registers itself and opens a browser for consent, and the resulting token is held by your client. We never see a password, and you can revoke access at any time from your account settings.
