Can this package be used for third-party applications?

[informatJonas]

Hi,

I'm trying to integrate Anthropic OAuth authentication into my own application using this package's approach.

I've copied the OAuth flow implementation with:

• Client ID: 9d1c250a-e61b-44d9-88ed-5944d1962f5e
• Scopes: org:create_api_key user:profile user:inference user:sessions:claude_code
• PKCE: S256 code challenge
• Redirect URI: http://localhost:41539/callback

However, I'm consistently getting a 400 Invalid request format error from claude.ai/oauth/authorize.

Questions:

1. Is this OAuth client ID registered only for OpenCode's specific redirect URIs?
2. Can third-party applications use this package/client ID with their own redirect URIs?
3. Or do we need to register our own OAuth application with Anthropic?

I couldn't find any public documentation on registering OAuth applications with Anthropic, so I'm wondering if this is only available to whitelisted partners.

Thanks for any clarification!

Why did you change the redirect uri?
