How to pass specified parameters through the LangGraph React Agent (these parameters should not be through natural language) to the MCP server environment?

Question
Currently, there's an issue I'm not sure how to resolve. The MCP server is invoked through an AI Agent, but the tools inside the MCP server need to call the business end, which requires a user token. The problem is how to pass the token to the MCP Server side. When the chat is triggered, the MCP server can retrieve the token that was previously passed manually.
