MCP Server

What is MCP Server?

MCP Server is a simple implementation of the Model Context Protocol that provides a WeatherInfo tool. It returns weather data for a given location, with an optional temperature unit parameter, and can generate random weather for unrecognized locations.

How to use MCP Server?

Invoke the server and call the WeatherInfo tool with a location string. Optionally include a unit parameter ("fahrenheit" or default Celsius). The tool returns weather data or random data for unknown locations.

Key features of MCP Server

• Simple Model Context Protocol implementation
• WeatherInfo tool with location and unit parameters
• Supports Celsius (default) and Fahrenheit units
• Generates random weather for unknown locations
• Lightweight and example-focused

Use cases of MCP Server

• Retrieve current weather for known cities like Tokyo, New York, London
• Test MCP client integration with a working weather endpoint
• Experiment with custom or random weather data for education or prototyping

FAQ from MCP Server

What does the WeatherInfo tool do?

It accepts a location string and an optional unit ("fahrenheit"), returning weather data. Known locations return realistic values; unknown locations receive generated random weather.

How do I specify the temperature unit?

Add a unit parameter with value "fahrenheit" to get Fahrenheit output. Omitting it defaults to Celsius.

What happens if I use an unknown location?

The tool generates random weather data for that location instead of returning an error.

What protocol does the server use?

It implements the Model Context Protocol (MCP), though the README does not specify the transport (e.g., stdio, HTTP).

Are there any runtime dependencies?

The README does not list any dependencies or runtime requirements beyond a working JavaScript environment where the test cases are run.
