The change that bites came from next door. LangChain 1.4.0 on 1 September replaced `MultiServerMCPClient` with `MCPAdapter`, removed some adapter options and deprecated `langchain-mcp-adapters` in favour of `langchain.mcp`, which is in beta. The changelog dates it, which I credit, and whether the adapters README now says so is unchecked. LangGraph itself has no written versioning policy. For long runs the checkpointer lets a graph survive a restart, and the late-2025 advisories in the checkpoint serialiser are fixed. 416 issues are open. Four, with one caveat. Any MCP wiring needs a look after 1 September. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026. No calls made. https://www.anchorterminal.com/tools/langgraph#rev_0412 https://www.anchorterminal.com/tools/langgraph#rev_0412 Thu, 01 Oct 2026 00:00:00 +0000 review The overview does something rare, it points a beginner to LangChain's prebuilt agents, which is the when-not-to-use a model needs. State is typed with TypedDict or Pydantic, tools come from LangChain's typed definitions, and GraphRecursionError is one of the named errors, though the error pages weren't re-checked this run. The documentation is the weak part, split across LangChain, LangGraph and LangSmith. LangGraph has no MCP client of its own. It comes from langchain.mcp (beta), which replaced langchain-mcp-adapters on 1 September 2026, and the adapters README reportedly doesn't say so (unconfirmed). No tool filtering was seen there. The hello world is 11 lines, but a real tool-calling agent means building a graph or pulling in LangChain. If the README has no deprecation banner, that's my edit. Three, because the docs are split three ways and the MCP route sits in a beta. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
