my-first-mcp answer-first brief

My first MCP server - a simple weather tool I worked with Claude Code -by way of prompting- to build my first MCP server. It has two tools: get-weather and get-weekly-forecast: The first tool, “get-weather”, calls the API “open-meteo” to get dynamic weather updates from the city of choice. It accepts a string and returns the weather in the format: Location, Temperature, and Conditions. The second tool, “get-weekly-forcast” uses the same API to return a week’s Published capability contract available. No trust telemetry is available yet. Last updated 2/24/2026.

Freshness

Last checked 2/22/2026

Best For

Contract is available with explicit auth and schema references.

Not Ideal For

my-first-mcp is not ideal for teams that need stronger public trust telemetry, lower setup complexity, or more explicit contract coverage before production rollout.

1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Full README

I worked with Claude Code -by way of prompting- to build my first MCP server. It has two tools: get-weather and get-weekly-forecast:

The first tool, “get-weather”, calls the API “open-meteo” to get dynamic weather updates from the city of choice. It accepts a string and returns the weather in the format: Location, Temperature, and Conditions.

The second tool, “get-weekly-forcast” uses the same API to return a week’s worth of forecast in the format: “Here’s the seven day forecast for __ ”, followed by a table with columns labelled Date, High (temperature), Low (temperature), and Conditions.4

These tools are useful because it has Claude retrieve dynamic weather data through an external API instead of retrieving static weather data that could lead to inaccuracies.

Examples of usage:

-Use get-weather to tell me the weather in Boston -I want to plan a trip to Nashville, use get-weekly-forecast to show me the forecast of the next seven days -What's the weather in Kansas City?

Known limitations: -The server requires internet access, it will not work without it. -If the API is not available, the tool will not be able to return weather data.

To install my MCP server, follow these instructions:

Prerequisites

https://nodejs.org/ v18+

Setup

git clone <your-repo-url> cd my-first-mcp npm install

##Add to Claude Code

claude mcp add weather-server node /absolute/path/to/my-first-mcp/index.js

Or manually add to your MCP config:

{ "mcpServers": { "weather-server": { "command": "node", "args": ["/absolute/path/to/my-first-mcp/index.js"] } } }

Available Tools

get-weather — Get current weather for a location (temperature, conditions, humidity, wind)
get-weekly-forecast — Get a 7-day forecast for a location

Additional points:

No API keys needed — it uses the free https://open-meteo.com/ API
Uses stdio transport, so it's run directly by Claude Code (not as a standalone HTTP server)
npm start works too, but typically Claude Code launches it automatically via the MCP config
