Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Tools it offers3 tools · read 2026-10-27
  • search_deals

    Search current flight deals from Luxembourg (default) or nearby airports. Returns return-trip prices in EUR with dates, the usual route price, a booking link and when the price was last checked.

  • get_deal

    Get the current price of one deal by id. found=false means it is gone or expired.

  • list_destinations

    List destinations that have current deals, with the cheapest price and departure airports.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "deals": {
      "type": "http",
      "url": "https://mcp.flyscout.lu/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http flyscout https://mcp.flyscout.lu/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://mcp.flyscout.lu/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
