feat(langchain): bridge MCP elicitation to LangGraph interrupts Add opt-in elicitation support to `langchain.mcp`. Passing `elicitation="interrupt"` to `load_mcp_tools` (or `convert_mcp_tool`) surfaces modern-spec (2026-07-28) server elicitation as a LangGraph `interrupt()`: the tool drives the input-required loop and pauses the agent, resuming the call with the user's answer. Only servers speaking the modern input-required mechanism trigger this — older servers never return an `InputRequiredResult`, so plain calls are unchanged. Because we drive the loop on the graph node's own stack, the interrupt propagates cleanly (no server-initiated back-channel, no swallowed exceptions). The `MCPElicitation` type describes the interrupt payload for resume handlers.

feat(langchain): add `langchain.mcp` for loading MCP tools Adds an optional `langchain.mcp` module that turns the tools on an MCP server into LangChain tools. Connection concerns (transport, multi-server configuration, auth, protocol negotiation) are handled by the FastMCP client; this package only does the conversion. `load_mcp_tools(client)` returns `list[BaseTool]`. Install with `langchain[mcp]`, which pulls the lightweight `fastmcp-slim[client]`.

Connection concerns (transport, multi-server configuration, auth, protocol negotiation) are handled by the FastMCP client; this package converts tools and, optionally, bridges elicitation to human-in-the-loop. `load_mcp_tools(client)` returns `list[BaseTool]`. Pass `elicitation="interrupt"` to surface modern-spec (2026-07-28) server elicitation as a LangGraph `interrupt()` and resume the tool call with the user's answer. Install with `langchain[mcp]`, which pulls the lightweight `fastmcp-slim[client]`.
