Unified MCP Client Library: Connect Any LLM to Tools & Servers
9 months ago 高效码农Unified MCP Client Library: The Open-Source Bridge Between LLMs and Tools In the fast-evolving world of artificial intelligence, large language models (LLMs) such as OpenAI’s GPT series and Anthropic’s Claude are transforming how developers build smart applications. To unlock their full potential, integrating these models with external tools—like web browsing, file management, or 3D modeling—is often essential. However, this process can be complex and time-intensive. That’s where the Unified MCP Client Library (MCP-Use) comes in—a powerful, open-source Python library designed to make this integration seamless. MCP-Use enables developers to connect tool-calling LLMs to MCP (Multi-Capability Protocol) servers and create custom …
