Weather MCP Server: Demystifying Model Context Protocol Integration

Overview: What is the Weather MCP Server?

The Weather MCP Server project exemplifies the implementation of a Model Context Protocol (MCP) system for weather information, consisting of an advanced client leveraging OpenAI's agents and a dedicated MCP server. This weather-specific MCP server provides real-time and detailed weather data through natural language processing powered by GPT-4, making it an indispensable tool for developers looking to integrate MCP into their AI workflows.

🔧 Core Features & MCP Capabilities

The Weather MCP Server is designed with several core features that make it a robust solution for integrating Model Context Protocol capabilities. Key among these are:

1. Data Endpoint via SSE: The server exposes a weather information endpoint using Server-Sent Events (SSE), allowing continuous updates and efficient data transfer.
2. Tool Discovery for MCP Clients: Automatic identification of tools, like fetching current weather conditions, which are essential for users interacting with the API through MCP clients.
3. Serving on Localhost: The server runs locally at http://localhost:4000/sse, providing a seamless testing and development environment.

For detailed integration, the Weather MCP Server is compatible with various AI applications such as Claude Desktop, Continue, Cursor, and more. This compatibility ensures that developers can easily deploy this server within their own ecosystems to leverage real-world weather data. The current MCP client compatibility matrix indicates fully supported integrations for tools and prompts across multiple platforms:

MCP Client	Resources	Tools	Prompts	Status
Claude Desktop	✅	✅	✅	Full Support
Continue	✅	✅	✅	Full Support
Cursor	❌	✅	❌	Tools Only

This table highlights the diverse support structure of the Weather MCP Server, ensuring compatibility with a wide range of AI tools and platforms.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Weather MCP Server revolves around the Model Context Protocol (MCP) to ensure seamless communication between the client and server. The protocol implementation involves several layers:

1. SSE Endpoint: The server exposes an SSE endpoint at http://localhost:4000/sse for continuous data streaming.
2. Tool Discovery Mechanism: Implementation of a tool discovery mechanism allows automatic detection and integration of weather-related tools into the MCP client's workflow.
3. GPT-4 Integration: Utilizing OpenAI's GPT-4 model for natural language processing, the client can process requests related to weather information effectively.

🚀 Getting Started with Installation

To get started with installing and running the Weather MCP Server alongside its OpenAI Client, follow these steps:

1. Clone the Repository

   git clone [email protected]:sturlese/client_server_mcp.git
   cd client_server_mcp
   

2. Set Up Environment Variables

   • Create a .env file in both /server_weather/ and /client_weather_openai/.
   • Add the OpenAI API key:

     # Example of .env file
     OPENAI_API_KEY='your-api-key-here'
     

3. Install Dependencies

   • For the Server Component:

     cd server_weather/
     python3 -m venv venv
     source venv/bin/activate
     pip install -r requirements.txt
     

   • For the Client Component:

     cd ../client_weather_openai/
     python3 -m venv venv
     source venv/bin/activate
     pip install -r requirements.txt
     

💡 Key Use Cases in AI Workflows

The weather data provided by the Weather MCP Server can be integrated into various AI workflows, enhancing their functionality and user engagement. Here are two practical use cases:

1. Weather Chatbots: Integrate the Weather MCP Server with a chatbot system to provide timely and accurate weather updates to end-users.

   • Technical Implementation:

     import os
     from modelcontextprotocol.server_weather import fetch_weather
     
     # Initialize OpenAI Context Client
     openai_api_key = os.getenv("OPENAI_API_KEY")
     
     def get_weather_for_location(location):
         response = fetch_weather(openai_api_key, location)
         return response
     

2. Smart Home Integration: Use the server to provide weather-based smart home automation where users can command their devices based on current weather conditions.
