Prerequisites

• Node.js 18 or higher
• A WeatherXM Pro API key (get one at pro.weatherxm.com)

Configuration

The server requires a WeatherXM Pro API key to function. You'll need to provide this when connecting to the server.

Getting a WeatherXM Pro API Key

1. Visit pro.weatherxm.com
2. Sign up for a Pro account
3. Navigate to the API section
4. Generate an API key

Quick Fix for "Connection Failed" / "Load Failed"

The most common cause of connection failures is a missing or invalid WeatherXM Pro API key. Follow these steps:

1. Test Your API Key

Run this command to test your API key:

# Set your API key
export WEATHERXM_API_KEY="your_api_key_here"

# Test the connection
node test-api.js

2. Configure Your MCP Client

Option A: Environment Variable (Recommended)

export WEATHERXM_API_KEY="your_api_key_here"

Option B: MCP Client Configuration

For Claude Desktop or other MCP clients, add to your configuration:

{
  "mcpServers": {
    "weatherxm": {
      "command": "npx",
      "args": ["@oharkins/weatherxm-mcp-server"],
      "env": {
        "WEATHERXM_API_KEY": "your_api_key_here"
      }
    }
  }
}

Option C: Direct Server Configuration

If running the server directly:

WEATHERXM_API_KEY="your_api_key_here" npm run dev

MCP Client Configuration Examples

Using the Published NPM Package

For most users, the recommended approach is to use the published npm package:

{
  "mcpServers": {
    "weatherxm": {
      "command": "npx",
      "args": ["@oharkins/weatherxm-mcp-server"],
      "env": {
        "WEATHERXM_API_KEY": "your_api_key_here"
      }
    }
  }
}

Using Local Development Version

For developers or users who want to run the latest development version:

{
  "mcpServers": {
    "weatherxm": {
      "command": "node",
      "args": ["/path/to/weatherxm-mcp-server/dist/index.js"],
      "env": {
        "WEATHERXM_API_KEY": "your_api_key_here"
      }
    }
  }
}

Note: Replace /path/to/weatherxm-mcp-server with the actual path to your cloned repository. Make sure to run npm run build:tsc first to generate the dist/index.js file using the traditional TypeScript compiler.

Using Local Development with TypeScript

For active development with hot reloading:

{
  "mcpServers": {
    "weatherxm": {
      "command": "npm",
      "args": ["run", "dev"],
      "cwd": "/path/to/weatherxm-mcp-server",
      "env": {
        "WEATHERXM_API_KEY": "your_api_key_here"
      }
    }
  }
}

Note: This requires the development dependencies to be installed (npm install) and is only recommended for development purposes.

3. Verify the Connection

After configuration, the server should start successfully and you should be able to use weather tools like:

• "What's the weather like at station WXM123456?"
• "Find weather stations near New York City"
• "Get weather alerts for 40.7128, -74.0060"

Installation

1. Clone this repository:

git clone <repository-url>
cd weatherxm-mcp-server

2. Install dependencies:

npm install

3. Build the server:

Option A: Using Smithery (Default)

npm run build

Option B: Using Traditional TypeScript

npm run build:tsc

Note: The traditional TypeScript build creates a dist/ directory with compiled JavaScript files. Use this option if you prefer not to use Smithery or need the compiled output for deployment.

Development and Local Runner

This server supports both Smithery and local runner capabilities for development and testing.

Using Smithery (Recommended)

Smithery provides a modern development experience with hot reloading and optimized builds.

Development mode:

npm run dev

Build for production:

npm run build

Using Local Runner

For local development and testing without Smithery:

Set your API key:

export WEATHERXM_API_KEY="your_api_key_here"

Run the local runner:

npm run runner

Or run directly with tsx:

tsx src/runner.ts

Development Scripts

• npm run dev - Start Smithery development server
• npm run dev:tsc - Start development with TypeScript compiler
• npm run runner - Run local server for testing
• npm run build - Build with Smithery
• npm run build:tsc - Build with TypeScript compiler
• npm run clean - Clean build artifacts
• npm start - Run built server
• npm run start:dev - Run development server
• npm test - Test server creation

Configuration Files

The repository includes example configuration files for MCP clients:

• mcp-config-example.json - Standard configuration using the published npm package
• mcp-config-local-dev.json - Local development configuration

Copy and modify these files as needed for your MCP client setup.

Error: "Station not found"

• Try searching for stations first: "Find weather stations near [your location]"
• Use the station IDs returned by the search

Error: "API rate limit exceeded"

• Wait a few minutes before trying again
• Consider upgrading your WeatherXM Pro plan

Error: "WeatherXM service temporarily unavailable"

• The WeatherXM service may be experiencing issues
• Try again later

Common Issues

1. Missing API Key: The server requires a valid WeatherXM Pro API key
2. Invalid API Key: Double-check the key from your WeatherXM Pro account
