The Kiwi.com Flight Search MCP server integrates with various AI assistants, allowing users to seamlessly search for and book flights using the extensive Kiwi.com flight search engine. It exposes a powerful 'search-flight' tool that provides instant access to curated flight options. Users can specify detailed criteria including trip type (round-trip or one-way), origin and destination (city or airport), travel dates with flexibility, number and types of passengers, and preferred cabin class, with each search result including a direct booking link.
