About Search1API
Search1API MCP Server is the official MCP (Model Context Protocol) integration for Search1API. It provides a unified API for web search, news search, crawling, and site map functionality, supporting multiple search engines including Google, Bing, DuckDuckGo, Yahoo, X (Twitter), Reddit, GitHub, YouTube, arXiv, WeChat, Bilibili, IMDb, and Wikipedia. The server can be used remotely via OAuth or API key authentication, or run locally via stdio. It enables AI assistants to retrieve real-time web data and news articles directly through MCP.
