Anthropic adds self-hosted sandboxes and MCP tunnels to Claude Managed Agents

The development
Anthropic is decoupling tool execution from agent control in Claude Managed Agents, allowing enterprises to run sandboxes and MCP tunnels on their own infrastructure while keeping the core agent logic within Anthropic's platform. This hybrid model addresses a critical tension in enterprise AI adoption: companies gain data sovereignty and compliance flexibility without sacrificing the managed security and updates that cloud-hosted agents provide. The move signals Anthropic's recognition that agent deployment requires infrastructure choice, positioning Claude as viable for regulated industries where on-premise execution is non-negotiable.

Analyst takeOur AI-generated reading of the wider context and the next developments to watch.
The more consequential detail buried in this announcement is the control plane split itself: Anthropic retains agent orchestration logic while ceding execution infrastructure to the customer, which means Anthropic is betting that owning the reasoning layer is more defensible than owning the compute layer.
This is largely disconnected from recent activity in our archive, so the relevant context comes from the broader market. The pattern here mirrors what hyperscalers did with hybrid cloud a decade ago, offering infrastructure flexibility to close regulated-sector deals while keeping customers tied to a managed control surface. The MCP tunnel component is worth noting separately: MCP has been gaining adoption as a tool-connectivity standard, and Anthropic shipping native MCP infrastructure support inside a managed product suggests they are moving to make MCP a stickier part of their enterprise stack rather than a neutral open protocol.
Watch whether AWS or Google Cloud announces equivalent self-hosted execution options for their own managed agent products within the next two quarters. If they do, this becomes table-stakes parity; if they don't, Anthropic will have a concrete differentiator to close deals in financial services and healthcare where data residency requirements are legally binding.
