What

Settings expose three policies for AWS requests passing through the proxy, covering streaming, presigned and sigv4a requests. Each accepts deny or passthrough, and deny is documented as the default: the request fails closed with a 403. passthrough forwards it without re-signing, which the upstream service will reject on signature grounds.

Evidence

` deny (default) fails closed with a 403; passthrough forwards the request unre-signed (the upstream will reject its signature). `

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Under `auto`, your `user.message` events can lead the server to allow a call it would otherwise deny.

Confirmed since Anthropic's documentation has since written up deny, on Archive Session. The server decides each tool call individually: it judges, from the tool, its input, and the session content so far, whether the call is safe to execute or high-risk, and evaluates it to allow when judged safe and to deny when judged high-… api/beta/sessions/archive see the edit
