Model Context Protocol (MCP): A New Standard for Building Powerful LLM Applications
This article introduces the Model Context Protocol (MCP), an open protocol for building enterprise-grade Large Language Model (LLM) applications. MCP solves the problem of a lack of standardization in integrating LLMs with enterprise tools, allowing frameworks like LangChain to seamlessly integrate with various data sources and tools such as databases and GitHub. The article details MCP's core components (MCP server, client, and host), installation setup, and Python hands-on demonstrations. These include building a LangChain application to calculate simple and compound interest using Ollama, and interacting with multiple MCP servers using both stdio and sse transport modes. With MCP, LLM applications can more effectively leverage enterprise data and tools for more powerful functionality.
