The Short Version
Anthropic's February 2026 policy update explicitly prohibits routing Claude Free, Pro, or Max subscription OAuth tokens through third-party tools like OpenClaw — this is a documented Terms of Service violation. However, the claim overstates the scope: OpenClaw also supports Anthropic API key authentication, which is a separate credential path not covered by the subscription-token ban. The most common way users connect their subscription to OpenClaw does violate the ToS, but the blanket framing misses this important distinction.
