この更新の概要

エージェントセッションのステータス詳細や、ディープリンク使用時の警告表示方法が改善されました。MCPのタイムアウト設定に関する仕様変更や、一部の認証が必要なコネクタをウェブ版で設定する手順が追加されています。また、外部ツールの設定ファイル読み込み対象の拡大や、テレメトリにおけるOpenTelemetry準拠のID付与、WebFetchでのドメイン許可ルールの更新も含まれます。

The per-server `timeout` is a hard wall-clock limit per tool call, and progress notifications from the server do not extend it. Values below 1000 are floored to one second. For HTTP and SSE servers, the per-request fetch first-byte budget has a 60-second minimum regardless of this value, so only the tool-call watchdog honors smaller values.
The per-server `timeout` is a hard wall-clock limit per tool call, and progress notifications from the server do not extend it. Values below 1000 are ignored and fall through to `MCP_TOOL_TIMEOUT`, or to its default of about 28 hours when that variable is unset. Before v2.1.162, values below 1000 were floored to one second instead. For HTTP and SSE servers, the per-request fetch first-byte budget has a 60-second minimum.

A server you've added in Claude Code takes [precedence](#scope-hierarchy-and-precedence) over a claude.ai connector that points at the same URL. When this happens, `/mcp` lists the connector as hidden and shows how to remove the duplicate if you'd rather use the connector.
Some Anthropic-hosted connectors, such as Microsoft 365, Gmail, and Google Calendar, do not support local OAuth from Claude Code because the upstream identity provider only accepts the redirect URL that claude.ai registered. From v2.1.162, authenticating one of these hosts in `/mcp` shows a message directing you to connect it at Settings → Connectors on claude.ai instead. Once connected there, the connector appears in Claude Code automatically.
To disable claude.ai MCP servers in Claude Code, set the `ENABLE_CLAUDEAI_MCP_SERVERS` environment variable to `false`:

- Responses are cached for 15 minutes, so repeated fetches of the same URL return quickly.
- When a URL redirects to a different host, WebFetch returns a text result that names the original URL and the redirect target instead of following it. Claude then fetches the new URL with a second WebFetch call.
In the default and `acceptEdits` permission modes, WebFetch prompts the first time it reaches a new domain. To allow a domain in advance without a prompt, add a permission rule like `WebFetch(domain:example.com)`. The `auto` and `bypassPermissions` [permission modes](/en/permissions#permission-modes) skip the prompt entirely.
In the default and `acceptEdits` permission modes, WebFetch prompts the first time it reaches a new domain, except for a built-in set of preapproved documentation domains that fetch without a prompt. To allow another domain in advance without a prompt, add a permission rule like `WebFetch(domain:example.com)`. The `auto` and `bypassPermissions` [permission modes](/en/permissions#permission-modes) skip the prompt entirely.
An explicit `WebFetch(domain:...)` rule in `deny`, `ask`, or `allow` takes precedence over the preapproved set, so you can block a preapproved domain or require a prompt for it.
WebFetch sets a `User-Agent` header beginning with `Claude-User`, and an `Accept` header that prefers Markdown over HTML so servers that support content negotiation can return Markdown directly. [Sandbox](/en/sandboxing) network rules are configured separately, so a domain you want a sandboxed process to reach still needs an explicit sandbox permission rule.
