In LangChain, when converting MCP tools to StructuredTool, the langchain-mcp-adapters currently ignore the output schema of MCP tools, making it unable to transfer the MCP tool's output schema to Langgraph nodes' output messages

The MCP tool contains an output schema to describe the structure of tool’s output. But I found that langchain StructuredTool does not contain similar properties. when converting to StructuredTool, langchain-mcp-adapters ignores the outputSchema of mcps tools. Is there any way to read mcp tool’s output schema to langgraph node’s output message?
