🌅 導言：從「誰來執行」到「在哪裡執行」的範式轉移
2026 年 5 月 19 日，Anthropic 在 Code with Claude London 會議上宣布 Claude Managed Agents 的兩項重大更新：self-hosted sandbox（公共測試版）與 MCP tunnels（研究預覽版）。這兩項功能共同解決了一個核心問題：企業如何在託管代理的便利性与數據本地化合規之間取得平衡。
過去，Claude Managed Agents 的代理執行環境完全由 Anthropic 託管——企業將任務提交到 Anthropic 的雲端，代理在 Anthropic 的基礎設施上執行工具調用。這在合規層面產生了根本性矛盾：當代理需要存取企業內部的敏感資料（客戶數據、財務記錄、醫療資訊）時，Anthropic 的託管執行環境無法滿足數據本地化要求。
Self-hosted sandbox 與 MCP tunnels 的出現，標誌著 Anthropic 的企業信任模型從「信任 Anthropic 的基礎設施」轉向「信任客戶的基礎設施」。這是一個結構性的轉變，其影響遠超出技術細節本身。
🔍 技術解析：Self-hosted Sandbox 與 MCP Tunnels 的機制
Self-hosted Sandbox：將代理執行移入客戶基礎設施
Self-hosted sandbox 允許企業將代理的工具執行環境部署在客戶自己的基礎設施上——可以是本地數據中心、AWS、或任何其他託管提供者。關鍵約束包括：
- 工具執行在客戶環境中：敏感文件、軟體包和服務保留在客戶的基礎設施中
- 不支援 Anthropic 託管平台上的 AWS：目前 AWS 上的託管平台尚無法使用 self-hosted sandbox
- 記憶功能尚不支援自我託管執行：這是目前的架構缺口
- 需要明確的基礎設施安全評估：企業需要審查其沙箱環境的安全控制
從技術角度來看，self-hosted sandbox 的實現方式是在 Anthropic 的代理協調層與客戶的基礎設施之間建立一個安全的通道。代理仍然由 Anthropic 的 Claude 模型驅動（確保推理品質），但工具調用（文件讀取、API 呼叫、資料庫查詢）被路由到客戶的執行環境。
MCP Tunnels：安全暴露內部服務
MCP tunnels 提供了一個不同的安全模型：出站-only 的代理路徑。MCP tunnels 是一個小型堆棧（tunnel agent 加上 Anthropic 的路由代理），允許代理通過出站通道存取內部 MCP 伺服器——而不需要將內部服務暴露到外部網路。
關鍵特性：
- 出站-only 通道：代理只能向內部服務發送請求，不能從外部接收資料
- 需要訪問請求：目前處於研究預覽階段，需要 Anthropic 批准
- 內部 MCP 伺服器暴露：允許代理存取企業內部的 MCP 伺服器（如資料庫、CRM、ERP）
- 不需要 VPN 或防火牆規則變更：MCP tunnels 抽象了網路複雜性
⚖️ 核心權衡：合規成本 vs. 運營便利性的結構性取捨
合規成本：從「信任 Anthropic」到「信任你自己」
Self-hosted sandbox 的核心經濟學是：企業需要承擔基礎設施安全成本，以換取數據本地化合規。這意味著：
- 基礎設施安全成本增加：企業需要投資於沙箱環境的安全控制（訪問控制、日誌審計、漏洞掃描）
- 合規審計成本降低：數據本地化合規的審計成本減少，因為資料不再離開企業基礎設施
- 營運複雜性增加：需要維護客戶基礎設施上的沙箱環境，而不是依賴 Anthropic 的託管服務
MCP Tunnels 的安全模型：出站-only 的零信任路徑
MCP tunnels 的核心安全模型是零信任出站通道——代理只能向內部服務發送請求，不能從外部接收資料。這解決了傳統 MCP 部署的安全問題：
- 傳統 MCP 部署：代理直接存取內部的 MCP 伺服器，需要將內部服務暴露到外部網路
- MCP tunnels：代理通過出站通道發送請求，內部服務不需要暴露到外部網路
從安全角度看，MCP tunnels 的實現方式是在代理與內部 MCP 伺服器之間建立一個安全的通道，確保代理不能接收來自外部的惡意資料。
📊 可衡量指標：合規成本 vs. 運營效率
合規成本指標
| 指標 | 託管執行 | Self-hosted Sandbox |
|---|---|---|
| 數據本地化合規 | 不符合（資料離開企業） | 符合（資料保留在客戶基礎設施） |
| 合規審計成本 | 高（需要第三方審計） | 低（企業自行審計） |
| 基礎設施安全成本 | 低（Anthropic 承擔） | 高（企業承擔） |
運營效率指標
| 指標 | 託管執行 | Self-hosted Sandbox + MCP Tunnels |
|---|---|---|
| 工具調用延遲 | 低（本地網路） | 中（跨網路通道） |
| 代理協調品質 | 高（Claude 模型） | 高（Claude 模型） |
| 基礎設施維護成本 | 低 | 高 |
信任模型轉變
| 信任模型 | 託管執行 | Self-hosted Sandbox + MCP Tunnels |
|---|---|---|
| 信任 Anthropic 的基礎設施 | 高 | 低 |
| 信任客戶的基礎設施 | 低 | 高 |
| 總體信任度 | 中等（單一信任點） | 高（分散信任點） |
🏗️ 具體部署場景：企業信任邊界的重新定義
場景一：金融服務——合規強制性
在金融服務領域，數據本地化合規是強制性的（如 GDPR、HIPAA、PCI-DSS）。Self-hosted sandbox 的出現解決了一個根本性的合規矛盾：
- 過去：企業無法使用 Claude Managed Agents，因為代理執行環境在 Anthropic 的託管基礎設施上，無法滿足數據本地化要求
- 現在：企業可以使用 self-hosted sandbox，將代理執行移入客戶基礎設施，確保數據保留在企業內部
場景二：醫療保健——HIPAA 合規
醫療保健領域需要 HIPAA 合規，要求醫療資料保留在客戶基礎設施中。Self-hosted sandbox 解決了一個結構性矛盾：
- 過去：醫療機構無法使用 Claude Managed Agents，因為代理執行環境在 Anthropic 的託管基礎設施上
- 現在：醫療機構可以使用 self-hosted sandbox，確保醫療資料保留在客戶基礎設施中
場景三：政府部門——數據主權
政府部門需要數據主權，要求資料保留在國家邊界內。Self-hosted sandbox 解決了一個結構性矛盾：
- 過去：政府部門無法使用 Claude Managed Agents，因為代理執行環境在 Anthropic 的託管基礎設施上
- 現在：政府部門可以使用 self-hosted sandbox，確保資料保留在國家邊界內
🔮 結構性後果：AI 代理部署的合規經濟學
合規成本轉移：從 Anthropic 到企業
Self-hosted sandbox 與 MCP tunnels 的核心結構性後果是：合規成本從 Anthropic 轉移到了企業。這意味著：
- Anthropic 的合規成本降低：Anthropic 不再需要為企業數據本地化合規承擔成本
- 企業的合規成本增加：企業需要投資於基礎設施安全控制和審計
- 總體社會成本可能增加或減少：取決於企業基礎設施的安全控制是否優於 Anthropic 的託管環境
信任模型的結構性轉變
Anthropic 的信任模型從「信任 Anthropic 的基礎設施」轉向「信任客戶的基礎設施」。這是一個結構性的轉變，其影響遠超出技術細節本身：
- 單一信任點：企業只需要信任 Anthropic 的 Claude 模型（推理品質）
- 分散信任點：企業需要信任 Anthropic 的 Claude 模型 + 客戶的基礎設施（執行環境）
從安全角度看，分散信任點可能更安全，因為攻擊者需要同時攻入 Anthropic 的 Claude 模型和客戶的基礎設施。
📈 競爭影響：Anthropic 的企業信任定位
Anthropic 的企業信任定位轉變
Self-hosted sandbox 與 MCP tunnels 的出現，標誌著 Anthropic 的企業信任定位從「信任 Anthropic 的基礎設施」轉向「信任客戶的基礎設施」。這意味著：
- Anthropic 的企業信任定位：從「信任 Anthropic」轉向「信任客戶」
- 競爭優勢：Anthropic 成為唯一提供 self-hosted sandbox 與 MCP tunnels 的託管代理平台
- 合規成本：企業需要承擔基礎設施安全成本，以換取數據本地化合規
競爭對手的反應
- OpenAI：尚未宣佈類似功能，可能面臨合規壓力
- Google：可能面臨合規壓力，需要開發類似功能
- Microsoft：可能面臨合規壓力，需要開發類似功能
🔚 結論：從「誰來執行」到「在哪裡執行」的範式轉移
Claude Managed Agents + Self-hosted Sandbox + MCP Tunnels 的核心結構性意義是：AI 代理部署的信任模型從「信任 Anthropic 的基礎設施」轉向「信任客戶的基礎設施」。這是一個結構性的轉變，其影響遠超出技術細節本身。
從合規角度看，self-hosted sandbox 解決了一個根本性的合規矛盾：企業需要在託管代理的便利性与數據本地化合規之間取得平衡。從安全角度看，MCP tunnels 提供了一個零信任的出站通道，確保代理不能接收來自外部的惡意資料。
總體而言，Claude Managed Agents + Self-hosted Sandbox + MCP Tunnels 的出現，標誌著 Anthropic 的企業信任模型從「信任 Anthropic 的基礎設施」轉向「信任客戶的基礎設施」。這是一個結構性的轉變，其影響遠超出技術細節本身。

🌅 Introduction: The paradigm shift from “who will execute” to “where to execute”
On May 19, 2026, Anthropic announced two major updates to Claude Managed Agents at the Code with Claude London conference: self-hosted sandbox (public beta) and MCP tunnels (research preview). Together, these two capabilities address a core question: How enterprises balance the convenience of a managed agent with data localization compliance.
Historically, Claude Managed Agents’ agent execution environment was entirely hosted by Anthropic—enterprises submitted tasks to Anthropic’s cloud, and agents executed tool calls on Anthropic’s infrastructure. This creates a fundamental contradiction at the compliance level: when agents need to access sensitive data within the enterprise (customer data, financial records, medical information), Anthropic’s managed execution environment cannot meet the data localization requirements.
The emergence of Self-hosted sandbox and MCP tunnels marks Anthropic’s enterprise trust model from “trusting Anthropic’s infrastructure” to “trusting the customer’s infrastructure.” This is a tectonic shift with implications far beyond the technical details themselves.
🔍 Technical Analysis: The mechanism of Self-hosted Sandbox and MCP Tunnels
Self-hosted Sandbox: Move agent execution into customer infrastructure
Self-hosted sandbox allows enterprises to deploy the agent’s tool execution environment on the customer’s own infrastructure - be it an on-premises data center, AWS, or any other hosting provider. Key constraints include:
- Tool execution in customer environment: Sensitive files, packages and services remain in customer’s infrastructure
- AWS on Anthropic hosting platform not supported: self-hosted sandbox is not currently available on AWS hosting platform
- Memory does not yet support self-hosted execution: This is a current architectural gap
- Explicit Infrastructure Security Assessment Required: Enterprises need to review the security controls of their sandbox environments
From a technical perspective, the self-hosted sandbox is implemented by establishing a secure channel between Anthropic’s proxy orchestration layer and the customer’s infrastructure. The agent is still driven by Anthropic’s Claude model (ensuring inference quality), but tool calls (file reads, API calls, database queries) are routed to the client’s execution environment.
MCP Tunnels: Secure Exposure of Internal Services
MCP tunnels provide a different security model: outbound-only proxy paths. MCP tunnels are a small stack (tunnel agent plus Anthropic’s routing agent) that allows agents to access internal MCP servers through outbound tunnels - without exposing internal services to the external network.
Key features:
- Outbound-only channel: The proxy can only send requests to internal services and cannot receive data from outside
- Access Request Required: Currently in Research Preview and requires Anthropic approval
- Internal MCP server exposure: Allows agents to access internal MCP servers (such as databases, CRM, ERP)
- No VPN or firewall rule changes required: MCP tunnels abstract network complexity
⚖️ Core Tradeoff: Compliance Costs vs. Structural Tradeoffs of Operational Ease of Operation
Compliance Cost: From “Trust Anthropic” to “Trust Yourself”
The core economics of a self-hosted sandbox are: Enterprises bear the cost of infrastructure security in exchange for data localization compliance. This means:
- Increased infrastructure security costs: Enterprises need to invest in security controls for sandbox environments (access control, log auditing, vulnerability scanning)
- Reduced compliance audit costs: Audit costs for data localization compliance are reduced because data no longer leaves the enterprise infrastructure
- Increased operational complexity: Requires maintaining sandbox environments on customer infrastructure rather than relying on Anthropic’s managed services
Security Model for MCP Tunnels: Outbound-only Zero Trust Path
The core security model of MCP tunnels is Zero Trust Outbound Tunnel - the proxy can only send requests to internal services and cannot receive data from the outside. This solves the security issues of traditional MCP deployments:
- Traditional MCP deployment: The agent directly accesses the internal MCP server, which requires exposing internal services to the external network
- MCP tunnels: The proxy sends requests through outbound channels, and internal services do not need to be exposed to the external network
From a security perspective, MCP tunnels are implemented by establishing a secure channel between the proxy and the internal MCP server to ensure that the proxy cannot receive malicious data from the outside.
📊 Measurable Metrics: Compliance Costs vs. Operational Efficiency
Compliance Cost Metrics
| Metrics | Hosted Execution | Self-hosted Sandbox |
|---|---|---|
| Data localization compliance | Not compliant (data leaves the enterprise) | Compliant (data remains in customer infrastructure) |
| Compliance audit cost | High (requires third-party audit) | Low (company self-audits) |
| Infrastructure security costs | Low (borne by Anthropic) | High (borne by enterprises) |
Operational efficiency indicators
| Metrics | Hosted Execution | Self-hosted Sandbox + MCP Tunnels |
|---|---|---|
| Tool call latency | Low (local network) | Medium (across network channels) |
| Agent coordination quality | High (Claude model) | High (Claude model) |
| Infrastructure maintenance costs | Low | High |
Trust model transformation
| Trust Model | Hosted Execution | Self-hosted Sandbox + MCP Tunnels |
|---|---|---|
| Trust Anthropic’s infrastructure | High | Low |
| Trust customer infrastructure | Low | High |
| Overall trust | Medium (single trust point) | High (distributed trust points) |
🏗️ Specific deployment scenario: redefinition of enterprise trust boundaries
Scenario 1: Financial services - mandatory compliance
In financial services, data localization compliance is mandatory (e.g. GDPR, HIPAA, PCI-DSS). The emergence of Self-hosted sandbox solves a fundamental compliance contradiction:
- Past: Enterprises were unable to use Claude Managed Agents because the agent execution environment was on Anthropic’s managed infrastructure, which did not meet data localization requirements
- Now: Enterprises can use self-hosted sandbox to move agent execution into customer infrastructure, ensuring data remains on-premises
Scenario 2: Healthcare – HIPAA Compliance
Healthcare requires HIPAA compliance, which requires medical data to be retained within the customer infrastructure. Self-hosted sandbox solves a structural contradiction:
- PAST: Healthcare organizations were unable to use Claude Managed Agents because the agent execution environment was on Anthropic’s managed infrastructure
- Now: Healthcare organizations can use self-hosted sandbox to ensure medical data remains within the customer infrastructure
Scenario 3: Government departments - data sovereignty
Government departments require data sovereignty, requiring data to remain within national borders. Self-hosted sandbox solves a structural contradiction:
- Past: Government agencies were unable to use Claude Managed Agents because the agent execution environment was on Anthropic’s managed infrastructure
- Now: Government agencies can use self-hosted sandboxes to ensure data remains within country boundaries
🔮 Structural Consequences: Compliance Economics of AI Agent Deployment
Compliance Cost Shift: From Anthropic to Enterprise
The core structural consequence of the Self-hosted sandbox and MCP tunnels is that compliance costs are shifted from Anthropic to the enterprise. This means:
- Reduced Compliance Costs for Anthropic: Anthropic no longer has to bear the cost of enterprise data localization compliance
- Increased compliance costs for businesses: Businesses need to invest in infrastructure security controls and audits
- Overall Social Costs May Increase or Decrease: Depending on whether the security controls of the enterprise infrastructure are superior to those of Anthropic’s hosted environment
Structural shifts in trust models
Anthropic’s trust model shifts from “trusting Anthropic’s infrastructure” to “trusting the customer’s infrastructure.” This is a tectonic shift with implications far beyond the technical details themselves:
- Single Point of Trust: Enterprises only need to trust Anthropic’s Claude model (inference quality)
- Decentralized Trust Points: Enterprises need to trust Anthropic’s Claude model + the customer’s infrastructure (execution environment)
From a security perspective, decentralizing trust points may be safer, since an attacker would need to compromise both Anthropic’s Claude model and the customer’s infrastructure.
📈 Competitive Impact: Anthropic’s Enterprise Trust Positioning
Anthropic’s Transformation of Enterprise Trust Positioning
The emergence of Self-hosted sandbox and MCP tunnels marks Anthropic’s corporate trust positioning from “trusting Anthropic’s infrastructure” to “trusting customers’ infrastructure.” This means:
- Anthropic’s enterprise trust positioning: From “trusting Anthropic” to “trusting customers”
- Competitive advantage: Anthropic becomes the only hosted proxy platform to offer self-hosted sandbox and MCP tunnels
- Compliance Cost: Enterprises need to bear the cost of infrastructure security in exchange for data localization compliance
Competitor reaction
- OpenAI: Similar features have not been announced yet and may face compliance pressure
- Google: may face compliance pressure and need to develop similar functions
- Microsoft: May face compliance pressure and need to develop similar features
🔚 Conclusion: Paradigm shift from “who will execute” to “where to execute”
The core structural significance of Claude Managed Agents + Self-hosted Sandbox + MCP Tunnels is: The trust model deployed by AI agents shifts from “trusting Anthropic’s infrastructure” to “trusting the customer’s infrastructure”. This is a tectonic shift with implications far beyond the technical details themselves.
From a compliance perspective, self-hosted sandbox solves a fundamental compliance contradiction: enterprises need to balance the convenience of a hosting agent with data localization compliance. From a security perspective, MCP tunnels provide a zero-trust outbound channel to ensure that the proxy cannot receive malicious material from the outside.
Overall, the emergence of Claude Managed Agents + Self-hosted Sandbox + MCP Tunnels marks the shift in Anthropic’s enterprise trust model from “trusting Anthropic’s infrastructure” to “trusting the customer’s infrastructure.” This is a tectonic shift with implications far beyond the technical details themselves.
