What is 🌦️ MCP Weather Scraper?

An experimental MCP (Model Context Protocol) server that uses OpenAI and FastAPI to fetch and structure real-time weather information from open web sources. It is designed for developers exploring how LLMs can interact with tools to retrieve and reason over unstructured web data.

How to use 🌦️ MCP Weather Scraper?

After cloning the repo, creating a virtual environment, installing dependencies, and setting the OPENAI_API_KEY environment variable, start the server with uvicorn server:app --reload. The server listens at http://localhost:8000. You can send a POST request to /weather with a JSON body containing a "location" field (e.g., {"location": "Seattle"}) using client.py or curl.

Key features of 🌦️ MCP Weather Scraper

Integration with OpenAI LLM (e.g., gpt-3.5-turbo)
FastAPI server exposing weather as a callable MCP tool
Automatic HTML parsing using selectolax for performance
Streamlit app frontend for user interaction
Response caching and token usage metrics

Use cases of 🌦️ MCP Weather Scraper

Fetching structured current weather data for any location
Integrating real-time weather retrieval into AI agent workflows
Prototyping MCP-based tool‑calling systems with LLMs
Exploring how LLMs parse unstructured web content into structured schemas

FAQ from 🌦️ MCP Weather Scraper

What is the Model Context Protocol (MCP)?

MCP is a new protocol for tool‑calling in LLMs that powers structured AI‑agent communication.

What are the runtime requirements?

Python 3.9 or higher and dependencies listed in requirements.txt. You also need an OpenAI API key stored in a .env file.

How does the server fetch weather data?

The server performs a browser search on open web sources and uses selectolax (a high‑speed HTML parser) to extract raw weather content. The LLM then structures that content into a JSON response.

Does this server have a user interface?

Yes, a Streamlit app frontend is included. It displays results along with response time, prompt tokens, completion tokens, and total tokens per request.

What transport and authentication does the server use?

The server uses HTTP (FastAPI) and authenticates with an OpenAI API key via an environment variable. There is no additional authentication for the server endpoint itself.
