langchain 1.4.0a2 (Aug 28) introduces langchain.mcp, a first-party adapter that turns any MCP server into LangChain tools usable directly with create_agent, supporting multi-server configs, OAuth/bearer auth, response caching, and human-in-the-loop elicitation via LangGraph interrupts. The maintainers warn the interface may shift before 1.4.0 final.

Почему это важно

MCP-to-agent tool bridging until now lived in community packages; a first-party adapter makes MCP servers a default integration surface for LangChain agents.
