I’m developed an MCP server and need to implement user-specific tools (e.g., get_balance, get_order_status).
Currently, the MCP server lacks a standard way to identify the end-user or receive their authentication token from the host client. To make this work, we need:
- Pass-through Headers: A way to forward auth tokens to the MCP server.
- User Context: A method to distinguish requests between different users.
Are there plans to support identity propagation in the MCP spec?
