237 Web search is enabled for your organization unless an administrator has disabled it in the [Claude Console](https://platform.claude.com/settings/privacy), where they can also restrict which domains it searches. If it's disabled, a request that includes the tool fails with a 400 `invalid_request_error` that says web search is not enabled, rather than an [error code](https://platform.claude.com/docs/en/agents-and-tools/tool-use/web-search-tool#errors) inside a search result.

240240These organization-level settings in the Claude Console apply to Messages API requests only. [Claude Managed Agents](https://platform.claude.com/docs/en/managed-agents/overview) sessions use only the per-tool `allowed_domains` and `blocked_domains` lists on the agent toolset; see [Restrict web search and web fetch domains](https://platform.claude.com/docs/en/managed-agents/tools#restrict-web-search-and-web-fetch-domains).
