# What is mcp_use? mcp_use is an **open source library** that enables developers to connect any Language Learning Model (LLM) to any MCP server, allowing the creation of custom agents with tool access without relying on closed-source or application-specific clients. **Freedom & Flexibility**: Break free from vendor lock-in and build agents that work with any LLM provider and any MCP server combination. # Key Features Connect any LLM to any MCP server without vendor lock-in Support for any MCP server through a simple configuration system Simple JSON-based configuration for MCP server integration Compatible with any LangChain-supported LLM provider Connect to multiple MCP servers simultaneously for complex workflows Agents can dynamically choose the most appropriate MCP server for each task # Popular Use Cases Combine Playwright with filesystem servers for automated research workflows Connect database servers with Python execution for data processing pipelines Integrate Git, filesystem, and code execution servers for automated development tasks Build content pipelines with research, writing, and publishing capabilities Connect to external APIs and services through custom MCP servers Implement secure, auditable agent workflows with proper access controls # Supported MCP Servers mcp_use supports **any MCP server**, allowing you to connect to a wide range of server implementations for different use cases. Web scraping and browser automation capabilities Safe file system operations and management Database querying and management tools Repository management and GitHub API access Explore a comprehensive list of available MCP servers from the community - find servers for APIs, databases, cloud services, and more. # Why Choose mcp_use? Unlike proprietary solutions that lock you into specific LLM providers or platforms, mcp_use works with any LangChain-supported model and any MCP server, giving you complete freedom to choose the best tools for your needs. Built with security best practices in mind, featuring comprehensive input validation, access controls, audit logging, and secure configuration management for enterprise deployments. The server manager enables efficient resource utilization by connecting to servers only when needed, supporting complex multi-server workflows without unnecessary overhead. Simple configuration, comprehensive documentation, real-time streaming support, and extensive examples make it easy to get started and scale your implementations. **New to MCP?** The Model Context Protocol (MCP) is an open standard that enables secure connections between LLM applications and external data sources and tools.
