Yandex Search

Clone the official Yandex Search MCP server repository and install the Python dependencies listed in requirements.txt.

git clone https://github.com/yandex/yandex-search-mcp-server.git
cd yandex-search-mcp-server
pip install -r requirements.txt

Log in to Yandex Cloud (console.yandex.cloud), navigate to Search API, and create a service account with the `search-api.editor` role. Generate an API key with the `yc.search-api.execute` scope and note your Folder ID from the cloud console.

Export the two required environment variables before starting the server. These authenticate your requests to the Yandex Search API.

export SEARCH_API_KEY="your-yandex-search-api-key"
export FOLDER_ID="your-yandex-folder-id"

Edit your claude_desktop_config.json to add the Yandex Search MCP server, passing your API key and Folder ID as environment variables.

Restart Claude Desktop and ask it to search the web. Two tools are available: `web_search_post` for raw results with sources, and `ai_search_post` for AI-generated answers from Yandex Yazeka.
