Anthropic Blocks Claude Subscriptions via Third-Party Tools
Anthropic has taken action against third-party tools using Claude subscriptions through OAuth integrations. The company claims Claude Pro/Max subscriptions were being used at scale beyond what the subscriptions were designed for, calling it subsidized access being "taken advantage of."
Timeline of Events
- January 9: Anthropic quietly started implementing server-side blocks
- February 20: Formal policy was published
- April 4: "Extra Usage" billing kicked in, making third-party OAuth integrations economically unviable
The creator of OpenClaw, a tool affected by these changes, was hired by OpenAI back in February, adding context to the situation. Users of OpenClaw reported receiving emails about the tool breaking due to these policy changes.
This type of restriction is common when companies detect usage patterns that exceed intended subscription models, particularly with API-based services where third-party tools can aggregate access.
