Describe the feature or problem you’d like to solve

PATs are long lived credentials that are discouraged, and sometimes entirely restricted in many organizations. This limits the organizations from taking advantage of this MCP server.

Proposed solution

Please provide an alternative Auth method, e.g an OAuth with adevice_code, in addition to the PAT, to enhance security and enable adoption within the aforementioned organizations.
