On November 12, 2026, Anthropic opened a private beta of self-hosted Claude Managed Agents, letting companies move the entire Claude agent service into their own cloud or on-premises data centers, so the credentials, sandboxes, and session history their agents use no longer live on Anthropic's servers. The model itself does not move — inference requests still go to a provider the customer chooses — and that boundary is the key to understanding this update.
What moves in-house, and what stays out
The hosted Claude Managed Agents service launched in April 2026, and self-hosted sandboxes followed in May; this private beta hands companies the rest. On the customer side there are three pieces to run: cma-server, which serves the API, drives the agent loop, and stores agents and session records; a PostgreSQL 16 or later database holding those records — without it, history is lost on restart; and workers that run the agent's shell and file operations inside sandboxes. Model calls can go through Anthropic by default, or to Amazon Bedrock, Claude models on Google Cloud, Microsoft Foundry, or a company's own model gateway. Anthropic says it has no remote access to a customer's self-hosted server or logs.
Who needs this first
The first to benefit are industries sensitive about data leaving their premises: in finance, healthcare, and government, agents fixing builds, running tests, triaging alerts, and clearing bug backlogs already work unattended inside internal systems for hours, and keeping credentials and session history inside the company's own boundary makes compliance review far easier. But the cost moves too: companies install and upgrade each release themselves, and operational responsibility no longer sits with Anthropic. The private beta is also not a full copy of the hosted service — scheduled deployments, dreams, and webhooks are not supported yet, web search and fetching stay off until manually enabled, and access runs only through Anthropic's account team, with no pricing and no date for general availability announced.
Companies already on the hosted service should not rush to migrate: the private beta offers no migration of hosted data, so agents, skills, credential stores, and session history all have to be rebuilt. The more realistic path is to run a small pilot first, work out the operating cost of the three pieces, and then decide whether to bring the whole agent pipeline home.
