LangChain TypeScript Client

About

This client allows LangChain agents built with TypeScript to leverage the capabilities of Model Context Protocol (MCP) servers. It utilizes the `@h1deya/langchain-mcp-tools` package to convert MCP server tools into LangChain-compatible tools, supporting LLMs from Anthropic, OpenAI, and Groq. Configuration is managed via a JSON5 file, allowing for easy customization and environment variable integration. This setup simplifies the process of integrating external tools and services into LangChain-powered applications.
