🚢 Deployment

Deploy to Render

Steps:

1. Click the "Deploy to Render" button above or go to render.com

2. Connect your GitHub account to Render (if you haven't already)

3. Create a new Web Service:

   • Connect this repository

   • Name: weather-mcp

   • Environment: Python 3

   • Plan: Free

   • Build Command: pip install -r requirements.txt

   • Start Command: python src/server.py

4. No environment variables required

5. Deploy!

Note: On Render's free tier, services go idle after ~15 minutes of inactivity and may require a manual "Deploy" to wake or to pick up the latest commit. Unlike Vercel, pushes do not auto-deploy by default.

Your server will be available at https://weather-mcp.onrender.com/mcp

🎯 Poke Integration

1. Go to poke.com/settings/connections

2. Add the MCP URL: https://weather-mcp.onrender.com/mcp

3. Give it a name like "Weather"

4. Try: "Use the Weather MCP to get the 3-day forecast for Boston."

🔧 Available Tools

• get_current_weather(location, units="metric|imperial"): Current conditions based on NWS forecast periods

• get_forecast(location, days=1..5, units="metric|imperial"): Multi-day forecast (day/night periods)

• get_weather_alerts(location): Official alerts/watches/warnings for the specified location

📝 Example Usage

# Get current weather (uses NWS forecast period closest to now)
get_current_weather(location="Seattle", units="metric")

# Get 3-day forecast (day/night periods)
get_forecast(location="New York", days=3, units="imperial")

# Get weather alerts
get_weather_alerts(location="Miami")

Notes:

• Locations are resolved via a simple built-in mapping of major US cities. For other places, default coordinates are used. You can extend this with a geocoding service if needed.

• Current conditions are derived from the first forecast period when station observations are unavailable.
