weather-server MCP Server
A Model Context Protocol server
This is a TypeScript-based MCP server that implements a simple weather service. It demonstrates core MCP concepts by providing:
- A resource for getting the current weather
- A tool for getting a weather forecast
Features
Resources
- List and access the current weather via a
weather://URI - The resource provides temperature, conditions, humidity, and wind speed.
Tools
get_forecast- Get the weather forecast for a city.- Takes a city name and number of days (1-5) as parameters.
Development
Install dependencies:
npm install
Build the server:
npm run build
For development with auto-rebuild:
npm run watch
Installation
To use with a compatible client, add the server config. For example, for Claude Desktop:
On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.jsonOn Windows: %APPDATA%/Claude/claude_desktop_config.json
{
"mcpServers": {
"weather-server": {
"command": "/path/to/weather-server/build/index.js"
}
}
}
Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:
npm run inspector
The Inspector will provide a URL to access debugging tools in your browser.
