Claude Code is Anthropic’s terminal coding agent. Run it in a Superserve sandbox so its shell commands and file edits stay isolated from your machine.

​
Via the console

  1. On the Secrets page, create a secret with the Anthropic provider and paste your API key — you only do this once, and the key never enters the sandbox.
  2. Go to console.superserve.ai and click Create sandbox.
  3. Pick the superserve/claude-code template (Claude Code preinstalled).
  4. Under Advanced Options → Secrets, bind that secret to ANTHROPIC_API_KEY.
  5. Create the sandbox, open its Terminal, and run claude.

​
Via the SDK

npm install @superserve/sdk
export SUPERSERVE_API_KEY=ss_live_...

import { Sandbox, Secret } from "@superserve/sdk"

// One-time: store your key as a secret. It never enters the sandbox.
await Secret.create({
  name: "anthropic-key",
  value: "sk-ant-...",
  provider: "anthropic",
})

const sandbox = await Sandbox.create({
  name: "claude-code",
  fromTemplate: "superserve/claude-code",
  secrets: { ANTHROPIC_API_KEY: "anthropic-key" },
})
Claude Code reads ANTHROPIC_API_KEY as usual, but its value is a stand-in token — the real key is attached only on requests to Anthropic, never exposed to the agent. Open the sandbox in the console, launch the terminal, and run claude.

Persist sessions

await sandbox.pause()    // checkpoint state to disk
await sandbox.resume()   // restore exactly where you left off
