Rec Us

Automate tennis court bookings on San Francisco Recreation websites using a Cloudflare MCP (Model Context Protocol) server with browser automation. Never miss your favorite court and court time again!

It uses Stytch to authenticate the server so only certain emails (like mine) can book a court (in my name.)

What This Does

This MCP server has 3 tennis booking tools:

• Check Court Availability - See available time slots for any court/date
• Book Court & Request SMS - Automate booking flow up to SMS verification
• Complete Booking with SMS - Finish booking by entering your SMS code

Quick Deploy

Deploy to Workers

This will deploy your tennis booking MCP server to: tennis-booking.<your-account>.workers.dev/sse

Alternatively, clone and deploy locally:

npm create cloudflare@latest -- tennis-booking-mcp --template=cloudflare/ai/demos/remote-mcp-authless

How the tennis booking works

1. Check what's available:

check_tennis_courts({
  court: "Alice Marble", 
  date: "2025-07-29", 
  time: "12:00 PM"
})

2. Start booking process (stops at SMS step)

book_and_request_sms({
  court: "Alice Marble",
  time: "12:00 PM", 
  date: "2025-07-29"
})

3. Manual SMS + Automated Completion (User gets verification code from rec.us, types it in to MCP server message, this tool then runs)

enter_sms_code_and_complete({code: "123456"})
