253253 The active profile is `AWS_PROFILE` if set, otherwise `default`. Set `AWS_SHARED_CREDENTIALS_FILE` or `AWS_CONFIG_FILE` to point at non-default file paths.

255 Run `/status` to see the resolved region. When the region came from your AWS config files or the default fallback, Claude Code also notes the source in the `/status` output. On v2.1.171 and earlier, Claude Code doesn't read the AWS config files, so set `AWS_REGION` explicitly.

256256* When using Amazon Bedrock, the `/logout` command is unavailable since authentication is handled through AWS credentials.
257257* The WebSearch tool is not available on Amazon Bedrock. See [WebSearch tool behavior](/docs/en/tools-reference#websearch-tool-behavior).
258258* You can use settings files for environment variables like `AWS_PROFILE` that you don't want to leak to other processes. See [Settings](/docs/en/settings) for more information.

490Claude Code constructs the endpoint URL from the AWS region. As of v2.1.172, the region is resolved with the same precedence as [Amazon Bedrock above](#3-configure-claude-code); earlier versions use `AWS_REGION` only. To override the URL for a custom endpoint or gateway, set `ANTHROPIC_BEDROCK_MANTLE_BASE_URL`.
