Connects Claude and other MCP clients to the Waitlister API for managing product launch waitlists through natural language. Exposes five core operations: adding subscribers with optional referral tracking and custom metadata, listing and sorting subscribers by position or referral count, looking up individuals by email or ID, updating subscriber details and points, and logging page views for analytics. Requires a Waitlister Growth or Business plan for API access. Useful if you're running a waitlist campaign and want to manage subscribers, check leaderboard rankings, or update referral points without leaving your editor or chat interface. Rate limits are 60 to 120 requests per minute depending on your plan tier.

add_subscriber | Add a new subscriber to your waitlist |
list_subscribers | List subscribers with pagination and sorting |
get_subscriber | Get details for a specific subscriber by ID or email |
update_subscriber | Update a subscriber's name, phone, points, or metadata |
log_view | Record a waitlist page view for analytics |
