LangGraph
LangChain durable graph runtime for stateful agents with MCP adapters

About
Design agents that reliably handle complex tasks with LangGraph, an agent runtime and low-level orchestration framework.
Prevent agents from veering off course with easy-to-add moderation and quality controls. Add human-in-the-loop checks to steer and approve agent actions.
LangGraph’s low-level primitives provide the flexibility needed to create fully customizable agents. Design diverse control flows — single, multi-agent, hierarchical — all using one framework.
LangGraph’s built-in memory stores conversation histories and maintains context over time, enabling rich, personalized interactions across sessions.
