Framework for building LLM-powered applications with agents, chains, and RAG. Supports multiple providers (OpenAI, Anthropic, Google), 500+ integrations, ReAct agents, tool calling, memory management, and vector store retrieval. Use for building chatbots, question-answering systems, autonomous agents, or RAG applications. Best for rapid prototyping and production deployments.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LangChain - Build LLM Applications with Agents & RAG The most popular framework for building LLM-powered applications. ## When to use LangChain **Use LangChain when:** - Building agents with tool calling and reasoning (ReAct pattern) - Implementing RAG (retrieval-augmented generation) pipelines - Need to swap LLM providers easily (OpenAI, Anthropic, Google) - Creating chatbots with conversation memory - Rapid prototyping of LLM applications - Production deployments with LangSmith observability **Metrics**: - **119,000+ GitHub stars** - **272,000+ repositories** use LangChain - **500+ integrations** (models, vector stores, tools) - **3,800+ contributors** **Use alternatives instead**: - **LlamaIndex**: RAG-focused, better for document Q&A - **LangGraph**: Complex stateful workflows, more control - **Haystack**: Production search pipelines - **Semantic Kernel**: Microsoft ecosystem ## Quick start ### Installation ```bash # Core library (Python 3.10+) pip install -U langchain # With OpenAI pip install langchain-openai # With Anthropic pip install langchain-anthropic # Common extras pip install langchain-community # 500+ integrations …

How to install
mdr add orchestra-research/ai-research-skills/langchain@sha256:d47635059ac1a1a3The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
