Research direction
No files, tests, or entry points are mentioned. Start by reviewing the MCP client’s existing OAuth support and how it constructs the Authorization header, then determine where an externally supplied JWT could be provided. Done means the client can send the supplied bearer token on each call without requiring an OAuth 2.1 server.

Description
I have been using the MCP OAuth support and even DCR, which is awesome.
But there are other scenarios where we are building in using MCP Servers into some host that doesn't understand this protocol, or that doesn't have an OAuth 2.1 server available, but where we might have obtained a valid access token (Jwt Bearer token) through some other means.
In this case I would like to add this to the MCP client so that it can be passed in the Authorization: Bearer {jwt} header on each call.
Is there a good way to do this - and if not can there be a way that feel intuitive to provide that kid of 'out of band' auth support for the MCP calls?
