This Model Context Protocol (MCP) server lets AI assistants like Claude and Cursor use the Yandex Search API for searching the web. Yandex Search enables LLM agents to safely and easily find up-to-date information on the internet.
Connect directly to Yandex's hosted MCP server (no need to run it locally).

The Yandex Search MCP server includes the following tools:
- (NEW) ai_search_with_yazeka_post Performs a real-time web search and returns an AI-generated answer based on the search results using Yandex Yazeka AI model.
- web_search_post: Performs a real-time web search and returns an encoded XML of the search results page
