Non PAT auth method

[aSapien]

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 a device_code, in addition to the PAT, to enhance security and enable adoption within the aforementioned organizations.

Additional context

Example Github App auth: https://docs.github.com/en/apps/creating-github-apps/writing-code-for-a-github-app/building-a-cli-with-a-github-app

Hey folks! 👋 I'd love to take a stab at implementing the OAuth 2.0 device code flow as an alternative to PATs.

My plan:

• Integrate GitHub OAuth using the device_code grant
• Ensure it works cleanly with the current CLI setup
• Add documentation for setup and usage

Let me know if this is something you're open to having in a PR! 🙂
