LangChain · x · 2026-09-04
LangChain shipped a full revamp of its MCP integration to support the new stateless MCP spec. The integration now lives in the main langchain package, elicitation works via interrupts, and list endpoints are cacheable. The new adapter is built on top of FastMCP, which provides first-class transports, auth, connection management, protocol negotiation, caching, and callbacks.
