About #STEP 1: install uv
A weather MCP server example built with FastMCP and httpx, using the National Weather Service API. The README provides setup commands and starter code for developers learning to create an MCP server.
Key features
- 01FastMCP server setup
- 02Weather API integration with httpx
- 03National Weather Service API base URL
- 04Project setup with uv
Use cases
- 01Learning to scaffold a weather MCP server
- 02Starting a Python MCP project with uv
MCP support
The example initializes a FastMCP server named "weather"; the README shows server setup but does not specify exposed tools.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
