5**Deprecated**

107**Deprecated.** This Admin API endpoint is superseded by `/v1/tunnels` on the Claude API and will be removed after a migration window. New integrations should use [`/v1/tunnels`](/docs/en/api/beta/tunnels) with the `anthropic-beta: mcp-tunnels-2026-06-22` header and a WIF token carrying the `workspace:manage_tunnels` scope. Existing integrations continue to work with the `mcp-tunnels-2026-05-19` header and `org:manage_tunnels` scope during the migration window.
