Waitlister MCP Server — @waitlister/mcp

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

This is the official package, superseding waitlister-mcp (1.0.x). Existing waitlister-mcp configurations keep working, but new setups should use @waitlister/mcp — it adds account-key support, waitlist creation, stats, and deletion, and works on every plan.

What Can You Do With This?

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

• "Create a waitlist for my new product and give me the signup form URL"
• "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 — the free plan works
• An account API key (recommended), or a per-waitlist API key (Growth plan+)

Getting Your Key

Account key (recommended — works on every plan, covers every waitlist you own):

1. Log in to Waitlister
2. Go to Settings → API keys → create a key (wl_acct_…)

Per-waitlist key (legacy, Growth plan+): waitlist → Integrations → API access. You'll also need the waitlist key from the waitlist's settings.

Installation

Using npx (recommended)

No installation needed — just configure your MCP client:

{
  "mcpServers": {
    "waitlister": {
      "command": "npx",
      "args": ["-y", "@waitlister/mcp"],
      "env": {
        "WAITLISTER_ACCOUNT_KEY": "wl_acct_your-key"
      }
    }
  }
}

With an account key you can optionally add "WAITLISTER_WAITLIST_KEY": "your-waitlist-key" to set a default waitlist — otherwise each tool call can target any waitlist you own via its waitlist_key parameter (ask the assistant to run list_waitlists first).

{
  "mcpServers": {
    "waitlister": {
      "command": "npx",
      "args": ["-y", "@waitlister/mcp"],
      "env": {
        "WAITLISTER_API_KEY": "your-api-key",
        "WAITLISTER_WAITLIST_KEY": "your-waitlist-key"
      }
    }
  }
}

Global install

npm install -g @waitlister/mcp

Then configure with "command": "waitlister-mcp" and the same env.

Setup by Client

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows) with the JSON above.

Cursor

Go to Settings → MCP → Add new MCP server and use the same configuration.

Claude Code

claude mcp add waitlister --env WAITLISTER_ACCOUNT_KEY=wl_acct_your-key -- npx -y @waitlister/mcp
