Waitlister MCP Server

Waitlister MCP Server

An MCP (Model Context Protocol) server that connects AI assistants like Claude, Cursor, and Windsurf to the Waitlister API. Manage your waitlist subscribers through natural language.

What Can You Do With This?

Once connected, you can ask your AI assistant things like:

• "Add test@gmail.com to my waitlist"
• "How many subscribers do I have?"
• "Look up the subscriber john@acme.com"
• "Update John's points to 500"
• "Show me the top 10 subscribers by referral count"

Tools

Prerequisites

• Node.js 18+
• A Waitlister account on the Growth or Business plan (API access required)
• Your API key and waitlist key from the Waitlister dashboard

Getting Your Keys

1. Log in to Waitlister
2. Go to Integrations → API access → Generate API key
3. Your waitlist key is found in your waitlist settings
