# Anthropic blocked tools spoofing Claude Code to abuse Max subscriptions—$200/month for what costs $1,000+ via API. Mass bans, no warning. Here's what actually happened and how to use Oh My OpenCode the right way.

## Summary

In January 2026, Anthropic blocked third-party tools like Oh My OpenCode from using Claude Max subscriptions after users exploited OAuth authentication by spoofing Claude Code client headers to get unlimited API access at flat-rate pricing. The controversy highlighted ToS violations on both sides: developers spoofed headers to bypass restrictions, while Anthropic enforced zero-notice account bans. Oh My OpenCode is a multi-agent orchestration system featuring specialized agents (Sisyphus, Oracle, Librarian, etc.) that can now be used legitimately through API keys, OpenAI OAuth, or Google Gemini authentication instead of the blocked Claude subscription method.
