# Weather MCP — historical weather 1940–present, no API key

Queries historical and current weather for any location and time via Open-Meteo and NOAA. No API key required.

## Install

```
npx -y @weather-mcp/weather-mcp
```

## Configuration

```json
{
  "mcpServers": {
    "weather": {
      "command": "npx",
      "args": ["-y", "@weather-mcp/weather-mcp"]
    }
  }
}
```

## What it adds

Claude answers the chronolocation investigator's core question: "what were the weather conditions at this location at this time?" Was it raining in Tbilisi at 3pm on April 14, 2023? Was it overcast or sunny in Kyiv on this date? Historical weather is a ground-truth anchor for image authentication — confirming or refuting claimed timestamps based on sky conditions, wet pavements, and seasonal vegetation visible in the image.
