Anthropic Restricts Claude Access Through Third-Party Tools Like OpenClaw for Subscription Users

Apr 4, 2026

Anthropic announced on Friday evening that Claude subscription users will no longer be able to access the AI assistant through third-party tools like OpenClaw starting April 4th at 3PM ET, citing unsustainable demand from agent-driven usage. Users who want to continue using these external integrations will need to pay separately through a pay-as-you-go billing option beyond their existing subscriptions. The policy change may push subscribers toward Anthropic's own tools like Claude Cowork. OpenClaw was created by Peter Steinberger, who is now employed by OpenAI, adding competitive dynamics to the situation.
