Enable Bypass of OAuth with API TOKEN in MCP Server

I would like to propose a feature enhancement for the MCP server to support bypassing OAuth authentication using Cloudflare's API TOKEN. This functionality would improve the integration process with Cloudflare's services by offering a more streamlined authentication method.

I apologize if this feature already exists within the MCP server. After reviewing the current documentation and feature list, I couldn't find specifics regarding API TOKEN support. If this functionality is already available, please direct me to the related resources.

Start by reviewing the MCP server's current OAuth authentication documentation and implementation entry point; the issue does not name specific files or tests. Determine whether API token authentication is already supported, then define the token configuration, authentication flow, and verification criteria before changing code.
