Overview

Simple_mcp_server_with_langgraph is a lightweight server application that utilizes Langgraph for managing multiple MCP (Microcontroller Protocol) servers.

To use this project, run the client.py script to connect to the server. For multiple MCP servers, execute weather_server.py alongside client.py.

Easy setup for MCP server-client architecture - Support for multiple MCP servers - Built with Python 3.11 for modern compatibility

Managing communication between microcontrollers in IoT applications.
Simulating weather data collection from multiple sensors.
Developing and testing server-client interactions in a controlled environment.
