🌦️ Weather MCP Server

This is a little MCP server that tells you the weather for any city you want. I was specifically using Cursor.

Quick Start with Cursor

Run:
```
npm install
```
Build:
```
npm run build
```
Configure in Cursor:
- Go to Cursor Settings > Tools & Integrations to get to mcp.json.
- Add something like this:
```
{
  "mcpServers": {
    "weather-mcp": {
      "command": "node",
      "args": ["path/to/dist/main.js"]
    }
  }
}
```
- Refresh Cursor/your chat and it should work! You should be able to see the tool in Cursor settings if it's working.

What does it do?

🌍 Finds your city (Nominatim)
☀️ Gets the current weather (Open-Meteo)

How do I use it?

Once it's running and hooked up to an MCP client, you can ask stuff (Command + Shift + L) like:

"What's the weather in Honesdale, PA?"

How does it work?

main.ts: Handles weather requests.
Nominatim: Turns city names into coords.
Open-Meteo: Gives us the actual weather data.
