The Tavily MCP server implements the Model Context Protocol to provide AI agents with web search and data extraction tools. It offers four main capabilities: tavily-search for real-time web search, tavily-extract for intelligent data extraction from web pages, tavily-map for creating structured website maps, and tavily-crawl for systematic website exploration. It can be used as a remote MCP server, allowing AI coding assistants like Claude Code to access these tools without local installation by simply connecting to the hosted endpoint with an API key.
