What is Trip1 MCP + x402?
Trip1 MCP + x402 is an AI hotel booking agent that lets AI agents search, compare, and book hotels with on-chain crypto payments for developers and AI power users. It exposes hotel search, rate comparison, and reservation creation as four Model Context Protocol (MCP) tools — search_hotels, get_hotel_details, purchase_hotel, and get_order_details — that any MCP-compatible client can call in sequence.
The service covers more than 3 million properties across 200+ countries. When an agent calls purchase_hotel, trip1 responds with an x402 payment challenge; the agent then signs a USDC authorization on Base, and a facilitator submits the transfer. Settlement completes inside the same HTTP request, typically within about two seconds, with no wallet UI required. If no x402-capable wallet is attached, purchase_hotel returns a CoinGate URL as a fallback, allowing payment manually with USDC or 50+ other cryptocurrencies.
Trip1 MCP + x402 ships alongside a SKILL.md file that provides the agent with judgment — when to fire each tool, how to confirm booking details with the user, and how to recover when a rate drops between search and checkout. Compatible clients include Claude Desktop, Claude Code, ChatGPT, Cursor, Codex CLI, and Gemini CLI. This makes it a practical choice for any developer building an AI travel or expense automation workflow that needs end-to-end hotel booking without manual payment steps.
What is Trip1 MCP + x402 used for?
Trip1 MCP + x402 is primarily used for building AI agent workflows that autonomously search and book hotels, settling payment on-chain in USDC without manual steps. It is also used by developers integrating travel booking capabilities into MCP-compatible AI assistants and automation pipelines.

Questions about Trip1 MCP + x402
What is Trip1 MCP + x402 used for?
Trip1 MCP + x402 is used to give AI agents the ability to search, compare, and book hotels autonomously. It exposes hotel inventory covering 3 million+ properties in 200+ countries as MCP tools, and handles payment in USDC on Base through the x402 protocol, settling in roughly two seconds. Developers integrate it into MCP-compatible clients like Claude Desktop, Claude Code, or ChatGPT to build end-to-end travel booking automations.
Is Trip1 MCP + x402 free?
Trip1 MCP + x402 does not publish its pricing publicly on the agents page. Interested users should contact the team directly for pricing details. The MCP server and SKILL.md can be installed via the Claude Desktop marketplace or npm, but commercial terms are not listed on the site.
How does Trip1 MCP + x402 work?
The agent calls search_hotels to find properties by destination, dates, and guest count, then get_hotel_details for room types and live availability, then purchase_hotel to create a reservation. Trip1 responds with an x402 payment challenge; the agent signs a USDC transfer on Base, a facilitator submits it, and settlement completes inside the original HTTP request in about two seconds. Finally, get_order_details is polled until the supplier returns a reservation reference.
What AI clients are compatible with Trip1 MCP + x402?
Trip1 MCP + x402 works with any MCP-compatible client, including Claude Desktop, Claude Code, ChatGPT, Cursor, Codex CLI, and Gemini CLI. The bundled SKILL.md judgment layer loads automatically in Claude Desktop and Claude Code installs. Clients that do not support SKILL.md, such as ChatGPT, still work using the tool descriptions embedded directly on the MCP server.
What is x402 and why does Trip1 use it?
x402 is an open protocol for agentic payments that revives the HTTP 402 status code for programmatic use. When an AI agent calls purchase_hotel, trip1 returns a 402 payment challenge rather than requiring a separate wallet UI interaction. The agent signs a USDC authorization on Base, a facilitator submits the on-chain transfer, and the booking resumes once it clears — allowing fully autonomous, human-free hotel payments.
