99Each [cloud session](/docs/en/claude-code-on-the-web) runs in a cloud environment. You can configure an environment to allow or deny [network access](#access-levels), [set environment variables](#set-environment-variables) for the session, store [network secrets](#add-network-secrets) that sessions use without seeing them, and run a [setup script](#setup-scripts) before Claude starts working.

2020Each of these surfaces can also route to a [self-hosted environment](/docs/en/self-hosted-environments). [Availability and limitations](/docs/en/self-hosted-environments#availability-and-limitations) covers what Claude can't use yet when a Claude Tag session runs in one.

23 [Remote Control](/docs/en/remote-control) sessions connect the web and mobile interfaces to a session on your own machine, which uses your machine's network and files, not a cloud environment. Claude Tag channel sessions use organization-level environments only, either [shared environments](#organization-shared-environments) or [self-hosted environments](/docs/en/self-hosted-environments).

8886Anyone who uses the environment can read the values. In an Anthropic-hosted environment, use a [network secret](#add-network-secrets) instead for a key the agent proxy can attach to a request. The [requests that never get a secret](#requests-that-never-get-the-credential) are listed there.

88### Add network secrets
9589
9690A network secret is an API key or token you store on a cloud environment so Claude can call that API from any session in the environment without seeing the key. Anthropic's agent proxy adds the key to requests for the hosts you list, after each request leaves the session's VM, so the key itself stays outside the VM.

from line 103

106#### Add a secret
115107
116108You add secrets one at a time, and you can't edit a secret after you add it. To change a secret's hosts or value, delete it and add it again.
117109
118110To add a secret to a [shared environment](#organization-shared-environments), open it for editing from the **Cloud environments** page in [admin settings](https://claude.ai/admin-settings), then continue step 1 from the **Network secrets** section. If you're on a Team plan and don't hold an [organization admin role](#requirements), follow step 1 on your own environment, then [fill in the shorter form](#add-a-secret-without-the-role).
119111
120<Steps>
121 <Step title="Open the environment's network secrets">
122 [Open the environment for editing](#configure-your-environment) at [claude.ai/code](https://claude.ai/code). In the **Edit cloud environment** dialog, find the **Network secrets** section. You see the secrets already on the environment, each with the hosts it applies to.
123 </Step>
124
125 <Step title="Add the secret">
126 Select **Add secret** and fill in the form. Keep the default **Secret type**, **Bearer**, for an API key that travels in a request header, and fill in these fields:
127
128 * **Name**: a label for the secret, such as `Internal billing API`
129 * **Allowed websites**: the API's hosts, such as `api.example.com`. A leading `*.` matches every subdomain
130 * **Custom headers**: one row for the header that carries the key. The row starts with `Authorization` as the header's **Name** and `Bearer` as its **Prefix**; paste the key itself as the **Value**. For a header like `X-Api-Key` that takes the bare value, change the name and clear the prefix
131
132 For an API that authenticates another way, pick a different **Secret type**. The list is the same one [Claude Tag](https://claude.com/docs/claude-tag/overview), the Slack integration for Team and Enterprise plans, offers for [connections](https://claude.com/docs/claude-tag/admins/add-connections).
133 </Step>
134
135 <Step title="Save the secret">
136 Select **Add**. The secret appears in the list with its hosts, saved without the dialog's **Save changes** button. You can't view the value again after saving.

139129
140130To confirm the secret works, start a session in the environment and ask Claude to call the API, for example with `curl`. The API answers as if the key were in the request, and the key doesn't appear in the session's environment variables or in any file. If the list marks a secret **Not sent** instead, the note under it says why and what to do. Two secrets whose hosts overlap without matching exactly get no marker, and the agent proxy sends only one of them.

156142The agent proxy attaches a secret to a request when the request's host matches one you listed on that secret. Sessions can reach those hosts even when the environment's [network access level](#access-levels) wouldn't otherwise allow them, except the [hosts that never get the secret](#requests-that-never-get-the-credential). The secret applies in every session that runs in the environment, whoever started it, until you delete it.

218202When you change an Anthropic-hosted environment's network access, its existing sessions follow the new setting within about a minute, for requests that go through the session's [network allowlist](#access-levels). You don't need to start a new session.

220<Note>
221 MCP connectors you enable on a session or scheduled task work without adding their hosts to **Allowed domains**, because connector traffic travels through Anthropic's servers rather than the session's network. This relies on the same Anthropic-bound channel noted under [Security and isolation](/docs/en/claude-code-on-the-web#security-and-isolation). Turn off any connector you don't need to limit which tools Claude can reach.

282266In Anthropic-hosted environments, each session gets a fresh virtual machine (VM) running Ubuntu 24.04 on x86\_64, regardless of your own operating system and CPU architecture, with your repository cloned and common toolchains pre-installed. When a dependency provides precompiled binaries, such as Ruby gems with native extensions or prebuilt Python wheels, use its x86\_64 Linux build to match the VM. This section covers the Anthropic-hosted defaults, the built-in GitHub tools, how to [run tests and services](#run-tests-start-services-and-add-packages), the [resource limits](#resource-limits) each VM gets, and the [time limits](#time-limits) on long-running work.

536520To confirm `npm install` succeeded, start a cloud session and ask Claude to show `node_modules/.install_pkgs.sha256`. The file lists a hash for each of the three files. If the file is missing, ask Claude to run `npm install` and report the error.
537521
538<Note>
539 If `npm install` reads other files, such as a workspace's `package.json`, an `.npmrc`, or your `postinstall` script's inputs, add them to the `sha256sum` command that saves the hashes. Otherwise, you keep the old packages after one of those files changes.
