Cruise Itinerary MCP server

Cruise Itinerary for Claude, ChatGPT and other MCP clients

Ask an AI assistant about cruises and get answers from real data: which sailings call at a port, what a ship's itinerary looks like day by day, how a sailing's fare has moved week by week, how much ship capacity reaches a port each month, and how cruise prices are trending overall.

This repository holds:

• the connection details for the Cruise Itinerary remote MCP server at https://cruise-itinerary.com/mcp,
• a Claude plugin that adds that server plus a cruise-research skill, which teaches Claude the data's caveats,
• server.json, the server's entry for the official MCP Registry.

The server is run by Cruise Itinerary (Agile Travel Group, Inc., operated as Cruiseable). The data is the same as its REST API: API docs, MCP docs.

What you can ask

• "Which sailings call at Juneau in July 2027, cheapest balcony first?"
• "Show me the day-by-day itinerary of that sailing."
• "Has the fare on this sailing gone up or down since September?"
• "How many berths of ship capacity reach Cozumel each month next winter?"
• "What does the Cruise Price Index say about fares this month?"

Tools

All tools are read-only (readOnlyHint: true). Each returns the same JSON as the matching REST endpoint, as structuredContent with an outputSchema.

A free account (an email address, no card) includes 500 calls a month. Every successful tool call counts as one API call. A tool above your plan answers with a short message, a link to pricing and, when the call named a sailing or cruise, a link to its free page on Cruiseable.

Setup

Claude (claude.ai, Desktop, mobile)

Add it as a connector: Customize → Connectors → Add custom connector, name it Cruise Itinerary, and paste https://cruise-itinerary.com/mcp. Claude detects the OAuth sign-in and asks you to sign in when you add it: enter your email, open the link we send, then approve the connection.

To get the cruise-research skill as well, install this repository as a plugin (below) or from the Claude directory once it is listed.

Claude Code

As a plugin (server and skill):

/plugin marketplace add BigBalli/cruise-itinerary-mcp
/plugin install cruise-itinerary@cruise-itinerary

Or the server only:

claude mcp add --transport http cruise-itinerary https://cruise-itinerary.com/mcp

Then run /mcp and choose cruise-itinerary to sign in.

ChatGPT

Add a custom app (connector) with the URL https://cruise-itinerary.com/mcp and OAuth authentication. Until the listing appears in the ChatGPT directory, this needs developer mode.

Cursor, VS Code, Windsurf and other clients

Point the client at the URL. Clients that support MCP OAuth sign in in the browser:

{
  "mcpServers": {
    "cruise-itinerary": {
      "url": "https://cruise-itinerary.com/mcp"
    }
  }
}
