# Semrush — how to use (mcp.ai)

Connect your Semrush account and use 37 tools for marketing straight from your AI agent. Connect with your own API key. Semrush is a popular SEO tool suite that specializes in keyword research, competitor analysis, and Google Ad campaign optimization.

## Option A — via MCP (recommended)

Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `semrush_account_units_balance`).

## Option B — via direct REST API
