MCP Server Tool Calling

Example Use Cases

• 1

  Perform arithmetic operations via a math server.

• 2

  Retrieve weather information through an HTTP-based weather server.

• 3

  That require integration of multiple MCP servers using different communication protocols.

Description

This project showcases integration of MCP servers with LangChain to provide custom tools for language models, including a math server for arithmetic operations and a weather server for weather lookups. It supports multi-protocol communication via stdio and HTTP, enabling flexible tool usage. The client uses a Groq model and LangChain's ReAct agent to intelligently call these tools and answer questions.
