# Memberstack — how to use (mcp.ai)

Connect your Memberstack account and use 8 tools for security and identity straight from your AI agent. Connect with your own API key. Memberstack is a platform that enables developers to add user authentication, payments, and member management to their websites without writing backend code.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_memberstack?ms=1787295660000`
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. `memberstack_create_member`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/memberstack`
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/memberstack/_endpoints`
