Published by Expedia Group itself, this server exposes the Travel Recommendation Service API to MCP clients, with both stdio and streamable HTTP transports so it fits local and remote setups alike.
Python, Apache-2.0. What makes it notable is provenance: a major distributor publishing its own MCP server under an open licence, rather than a third party reverse-engineering a public page. For anyone building travel agents in a commercial context, that distinction is the whole ballgame.
Expedia also operates a hosted remote MCP server if you would rather not run anything yourself.
