# Userlist — how to use (mcp.ai)

Connect your Userlist account and use 2 tools for marketing automation straight from your AI agent. Connect with your own API key. Userlist is a full-stack email automation platform designed for SaaS companies, enabling targeted behavior-based campaigns through email and in-app messages.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_userlist?ms=1787295720000`
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. `userlist_delete_company`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/userlist`
Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
Discover endpoints: `GET https://api.mcp.ai/api/userlist/_endpoints`

### Endpoints
