Claude OAuth Access Notice

TL;DR

Q. Can I use oh-my-opencode?

Yes.

Q. Can I use it with my Claude Code subscription?

Yes, technically possible. But I cannot recommend using it.

FULL

As of January 2026, Anthropic has restricted third-party OAuth access citing ToS violations.

Anthropic has cited this project, oh-my-opencode as justification for blocking opencode.

Indeed, some plugins that spoof Claude Code's oauth request signatures exist in the community.

These tools may work regardless of technical detectability, but users should be aware of ToS implications, and I personally cannot recommend to use those.

This project is not responsible for any issues arising from the use of unofficial tools, and we do not have any custom implementations of those oauth systems.
