Cloudflare has announced a new integration with Anthropic, bringing Claude Managed Agents directly into Cloudflare Sandboxes. This article serves as an announcement of a significant new feature and integration, not a critical alert or urgent action item. This move aims to provide developers with enhanced control, security, and scalability for their AI agent deployments, leveraging Cloudflare’s global network for autonomous AI operations. The announcement was made around May 20, 2026; while the precise date might vary slightly depending on regional rollouts or specific channels, this marks the general availability of the integration.

This integration addresses critical needs for developers building with AI agents: maintaining control over execution environments, securing access to internal services, and gaining visibility into agent behavior at scale.

What is the Integration?

The integration combines Anthropic’s Claude Managed Agents with Cloudflare Sandboxes. Previously, Claude Managed Agents often executed tools and code in Anthropic-managed cloud sandboxes. This partnership allows developers to host the execution environment within Cloudflare’s infrastructure.

This collaboration creates a secure and scalable foundation for autonomous AI agents. It effectively decouples the AI agent’s core logic, which remains with Anthropic, from its execution infrastructure, which now runs on Cloudflare’s global network.

Key Benefits for Developers

Developers adopting this integration gain several practical advantages for deploying and managing AI agents:

  • Enhanced Control over Agent Sandboxes: Developers can define and manage the sandbox environment where their Claude agents execute code and tools. This includes specifying resource limits, network policies, and runtime configurations.
  • Secure Connections to Private Services: Agents running within Cloudflare Sandboxes can establish secure, private connections to internal APIs, databases, and other services. This is crucial for agents that need to interact with sensitive enterprise data or infrastructure without exposing it publicly.
  • Improved Observability at Scale: The integration provides better tools and mechanisms for monitoring agent activity, performance, and resource consumption. This is vital for debugging, optimizing, and ensuring the reliability of AI agents in production environments.
  • Reduced Cold Starts: Cloudflare claims 5ms cold starts for agents deployed within their sandboxes, significantly improving responsiveness for agent-driven applications.
  • Global Network Edge: Leveraging Cloudflare’s network means agents can execute closer to users and data sources, potentially reducing latency and improving overall performance for globally distributed applications.

How it Works

The integration establishes Cloudflare Sandboxes as the execution environment for Claude Managed Agents’ tools and code. When a Claude Managed Agent needs to perform an action (e.g., call a tool, execute code), the orchestration logic remains with Anthropic, but the actual execution is delegated to a Cloudflare Sandbox.

This process involves:

  1. Agent Configuration: Developers configure their Claude Managed Agent, typically through the Anthropic API or platform, to specify a Cloudflare Sandbox as the designated execution environment for its tools. This involves providing Cloudflare with the definitions of the tools the agent can use and setting up the necessary permissions and endpoints.
  2. Orchestration by Claude: The Claude Managed Agent, managed by Anthropic’s infrastructure, processes user prompts and internal states. Based on its task and reasoning capabilities, it determines that a specific tool needs to be called or a piece of code needs to be executed to achieve its goal.
  3. Delegated Execution Request: Instead of executing the tool within Anthropic’s default sandbox, the Claude agent’s orchestration logic makes an API call to the developer-controlled Cloudflare Sandbox. This request includes details such as the tool’s name, its arguments, and a unique execution identifier.
  4. Secure Environment Execution: Cloudflare receives the execution request and dynamically provisions an isolated, ephemeral runtime environment within its global network – the Cloudflare Sandbox. This sandbox, often powered by WebAssembly (Wasm) or lightweight container technology, executes the specified tool or code.
    • Isolation: Each sandbox instance is isolated from other sandboxes and the underlying Cloudflare infrastructure, preventing unauthorized access or interference.
    • Developer Control: Developers define the sandbox’s characteristics, including CPU and memory limits, network egress rules, and access to secrets.
    • Private Connectivity: Through integrations like Cloudflare Tunnels, the sandbox can establish secure, private connections to internal APIs, databases, or other sensitive services within a developer’s private network, without exposing them to the public internet.
  5. Result and Telemetry Return: Upon completion, the Cloudflare Sandbox returns the execution result (e.g., tool output, success/failure status, error messages) back to Anthropic’s Claude Managed Agent. Simultaneously, the sandbox emits detailed telemetry data, including logs, metrics (e.g., execution duration, resource consumption), and potentially traces, to Cloudflare’s observability platform.
  6. Claude Agent Continues: The Claude Managed Agent receives the execution result and integrates it into its ongoing task, using the information to formulate a response to the user or to determine the next step in its autonomous operation. Developers can monitor the sandbox’s activity via Cloudflare’s dashboard and APIs.

Getting Started for Developers

For developers eager to leverage the enhanced control and security of Cloudflare Sandboxes for their Claude Managed Agents, here’s a clear path to getting started:

Prerequisites:

  • An active Cloudflare account.
  • An Anthropic API key and access to Claude Managed Agents.
  • Basic familiarity with Cloudflare Workers and the Cloudflare developer platform.

Steps to Configure Claude Managed Agents with Cloudflare Sandboxes:

  1. Set up your Cloudflare Sandbox Environment:

    • Begin by defining the execution environment for your agent’s tools using Cloudflare’s Sandbox SDK. This typically involves writing a Cloudflare Worker that acts as the interface for your tools, processing incoming execution requests from Claude.
    • You will define the tools your agent can call and implement the logic for each tool within this Worker.
    • Resource: Refer to the Cloudflare developer documentation for detailed guidance on creating a sandbox: Cloudflare Developers: Set up Claude Managed Agents

  2. Configure Secure Access to Private Services (Optional but Recommended):

    • If your Claude agent needs to interact with internal APIs, databases, or other services hosted within your private network, use Cloudflare Tunnels. Cloudflare Tunnels provide a secure, outbound-only connection from your private infrastructure to Cloudflare’s network, allowing your sandbox to access these services without exposing them publicly.
    • Resource: Explore Cloudflare Tunnels documentation for setup instructions.

  3. Deploy Your Sandbox to Cloudflare’s Edge:

    • Once your Worker-based sandbox is configured, deploy it to Cloudflare’s global network. This will provide you with a unique URL endpoint for your sandbox, which Claude will use to delegate tool execution.
    • Ensure your sandbox has appropriate permissions configured (e.g., access to KV stores, R2 buckets, or other Cloudflare services it might need).

  4. Configure Your Claude Managed Agent:

    • Within the Anthropic platform or via the Anthropic API, configure your Claude Managed Agent to use your deployed Cloudflare Sandbox endpoint for tool execution. This involves specifying the sandbox URL and potentially any authentication headers or API keys required by your Cloudflare Sandbox.
    • Resource: Consult Anthropic’s documentation on self-hosted sandboxes for specific agent configuration details: Anthropic: Self-hosted sandboxes - Claude API Docs

  5. Test and Monitor:

    • Run your Claude Managed Agent and observe its interactions. Use Cloudflare’s developer console, Workers Trace Analytics, and Logpush to monitor the execution of your tools within the sandbox. This allows for debugging, performance optimization, and ensuring secure operation.

Key Resources for Getting Started:
