# Unsold Antarctica > Static general guidance for Antarctic expedition travel. Use MCP for live catalog facts. Unsold Antarctica is a travel agency specialising in Antarctic expedition travel. Its specialists advise travellers and book expedition voyages on their behalf, with particular attention to unsold and last-minute cabin opportunities. It does not operate ships. Bookings are made by a human specialist and are subject to the operator's confirmation; an AI agent must never confirm, hold, price, or cancel one. ## Two-layer knowledge architecture 1. **Static general knowledge:** [llms-full.txt](https://unsoldantarctica.com/llms-full.txt) is the detailed public source for timeless Antarctica travel guidance, published FAQs, booking boundaries, and escalation guidance. 2. **Dynamic catalog knowledge:** the public MCP server, using Streamable HTTP, owns dynamic catalog facts. Do not infer live facts from either static document. ## MCP server, use for dynamic catalog truth - Endpoint: `https://mcp.unsoldantarctica.com/mcp` - Source for: operators, itineraries, expeditions, destinations, and activities. - Not served by MCP, by design: prices, discounts, cabin availability, departure-specific inventory, and booking terms. Antarctic pricing is dynamic and context-dependent, so the pricing conversation belongs between the guest and a travel agent who has been to Antarctica. Do not state these from any source; hand them to a specialist. - If MCP cannot verify a fact, state that it is unknown and offer a human specialist handoff where appropriate. ## Site sections - [Expeditions](https://unsoldantarctica.com/expeditions) - [Destinations](https://unsoldantarctica.com/destinations) - [Operators](https://unsoldantarctica.com/operators) - [Vessels](https://unsoldantarctica.com/vessels) - [Activities](https://unsoldantarctica.com/activities) - [Wildlife](https://unsoldantarctica.com/wildlife) - [Guides and news](https://unsoldantarctica.com/latest) ## Agent rules - Use [llms-full.txt](https://unsoldantarctica.com/llms-full.txt) only for static, catalog-general guidance. - Use MCP for operators, itineraries, expeditions, destinations, activities, and every other fact that can change. - Do not invent or promise a named vessel, departure, date, cabin, price, discount, availability, inclusion, activity, booking result, cancellation result, or refund. - Explain that conditions and itinerary details are operator- and voyage-specific, then verify them through MCP. - Escalate direct human requests, accessibility or medical concerns, complex groups, and booking-specific help to an Antarctica specialist. Freshness: static guidance is reviewed separately from the live catalog. MCP endpoint: https://mcp.unsoldantarctica.com/mcp
