What
The bundled platform availability reference no longer lists self-hosted environments on Claude Platform on AWS as "Not available". The self-hosted sandbox row now marks them supported and spells out how workers authenticate, how long a session can run unattended, and what a self-hosted session on AWS cannot do.
Details
- Workers authenticate either with IAM/SigV4 credentials or with an API key issued from the AWS Console that carries the
AnthropicSelfHostedEnvironmentAccessmanaged policy. - API keys generated in the Anthropic Console do not work against the AWS endpoint, so an existing Anthropic Console environment key has to be replaced with one of the two AWS methods.
- A session runs autonomously for at most 6 hours before it needs reauthentication; sending any user-role event continues it.
- Self-hosted environments on AWS cannot attach memory stores, and an attempt to do so is rejected at session create rather than failing later.
