Anthropic shipped three Claude Managed Agents updates on August 19, 2026: memory stores on self-hosted sandboxes, domain allow and block lists for `web_search` and `web_fetch`, and a rebuilt Console session viewer for multi-agent work. The same day, @ClaudeDevs posted the three items as one drop. Self-hosted sandbox sessions can save work to memory. The web tools accept `allowed_domains` or `blocked_domains`. Console now shows a minimap with one lane per agent, a streaming transcript grouped by agent iteration, and an inspector with cost in dollars per thread and per session. That is an operator release, not a new model. It closes three gaps teams hit once they run Managed Agents on their own infrastructure: persist state without leaving a self-hosted boundary, lock which sites tools may hit, and read per-agent cost and activity instead of a flat log. ## Self-hosted sessions can attach memory stores Managed Agents still execute tools in Anthropic-managed cloud sandboxes by default. Self-hosted sandboxes keep orchestration on Anthropic's side and move tool execution onto infrastructure you control. The agent's code, filesystem, and network egress stay in your environment. Tool inputs and outputs still flow to Anthropic's control plane so the model can see results and decide what to do next. Skills and the contents of any memory stores attached to the session are stored by Anthropic and copied into your sandbox for the session. Changes the agent makes to memory files sync back to the store. Until this release, that mount-and-sync path was the cloud-side story. The August 19 platform notes say sessions that run in a self-hosted sandbox can now attach memory stores. The Python, TypeScript, and Go SDK workers download each attached store into the sandbox at its `mount_path` and sync the agent's changes back to the store. Self-hosted sandbox docs spell out the filesystem contract. Stores materialize under `/mnt/memory/`, one directory per store at the store's `mount_path` — for example `/mnt/memory/user-preferences/`. The SDK worker creates those directories when it claims the session and removes them when the session ends. In cloud environments, Anthropic mounts stores at `/mnt/memory/`. In self-hosted environments, the SDK worker downloads them to `/mnt/memory/` and syncs writes. If sessions on the environment will attach memory stores, prepare `/mnt/memory` on the worker host before you start the worker. Claimed work items also carry a per-session `secret` the worker uses to mount stores. You do not generate that secret; in a sandbox-per-session pattern you forward it into the sandbox. The worker is a process you run on your own infrastructure. The `self_hosted` environment acts as a work queue: when a session is assigned to it, Anthropic enqueues the session as a work item. Your worker claims the item, downloads the agent's skills, runs the tool calls locally, and posts results back. @ClaudeDevs described the outcome in one line: any work done in a Self-Hosted Sandbox can be saved to memory. Self-hosting is the fit when the agent needs to operate on data that cannot leave your network boundary, reach internal services that are not publicly routable, or run under your organization's own compliance and audit controls. Memory stores no longer force that work back into a cloud sandbox. ## Domain lists on web_search and web_fetch You can now restrict which sites a Managed Agents agent's `web_search` and `web_fetch` tools can reach. Set `allowed_domains` or `blocked_domains` on the tool's entry in the `agent_toolset_20260401` `configs` array. `web_fetch` also accepts `max_content_tokens`. `web_search` also accepts `user_location`. Each `configs` entry is identified by its `name` and typed by an optional `type`. Requests that pass only `name`, `enabled`, and `permission_policy` continue to work. In the typed SDKs, `configs` entries become per-tool types. @ClaudeDevs stated the same control without the schema: `web_search` and `web_fetch` now take `allowed_domains` or `blocked_domains`, so you can control what the agent is allowed to search and read. Self-hosting already puts network egress under your policy. These fields are a separate layer on the agent toolset. They constrain the web tools themselves, whether or not the sandbox is self-hosted. The release notes do not say what happens when both lists are omitted, and they do not include an example domain list, so those details are unknown from the shipped notes. ## Console rebuilt for multi-agent sessions The session viewer in the Claude Console has been redesigned. Platform notes list a timeline minimap, a transcript grouped by model request, and an Inspector panel for session details and cost, raw events, per-tool statistics, mounted resources, and per-thread activity. The @ClaudeDevs thread is explicit about multi-agent layout: a minimap with one lane per agent, a streaming transcript grouped by agent iteration, and an inspector with cost in dollars per thread and per session. Taken together, operators get a lane-per-agent overview, a transcript that groups by request or iteration rather than a single undifferentiated stream, and an inspector that can answer cost, events, tools, resources, and thread activity without leaving the session. For multi-agent work, that is the difference between guessing which agent spent the budget and reading it. The three updates are live. If you already run a self-hosted worker, start with the memory-store section of the self-hosted sandbox docs: prepare `/mnt/memory` on the host, attach a store, and confirm the SDK worker materializes it at `mount_path`. Then set `allowed_domains` or `blocked_domains` on `web_search` and `web_fetch` in the agent toolset, and open a multi-agent session in Console to check the minimap, grouped transcript, and Inspector against cost and activity you already know. ## Sources - [Claude Platform release notes](https://platform.claude.com/docs/en/release-notes/overview) - [Self-hosted sandboxes](https://platform.claude.com/docs/en/managed-agents/self-hosted-sandboxes) - [@ClaudeDevs: three Managed Agents updates](https://x.com/ClaudeDevs/status/2090218983962390950)
