Semrush's official remote MCP server exposes its SEO API, Trends API (traffic and market data) and read-only Projects API to AI assistants. It uses Streamable HTTP with OAuth 2.1 by default, or an API key in the Authorization header. Access requires a qualifying Semrush plan with API units or a Trends API plan.
