Запуск mcp_react_agent.py падает с ошибкой:
File "C:\Program Files\anaconda3\envs\mcp\Lib\site-packages\langchain_mcp_adapters\client.py", line 167, in aenter
raise NotImplementedError(ASYNC_CONTEXT_MANAGER_ERROR)
NotImplementedError: As of langchain-mcp-adapters 0.1.0, MultiServerMCPClient cannot be used as a context manager (e.g., async with MultiServerMCPClient(...)). Instead, you can do one of the following:

1. client = MultiServerMCPClient(...)
   tools = await client.get_tools()
2. client = MultiServerMCPClient(...)
   async with client.session(server_name) as session:
   tools = await load_mcp_tools(session)
