Detailed Introduction
Claude Agent SDK WebSocket Server is an open-source project that wraps the Anthropic Claude Agent SDK into a WebSocket service, allowing developers to interact with Claude in real-time within local or E2B sandbox environments. The repository follows a monorepo layout including the server, client library, and E2B build scripts, enabling secure sandbox creation and message streaming via the @dzhng/claude-agent client.
Main Features
- Real-time WebSocket interaction that streams SDK query results to connected clients.
- E2B sandbox template build (
bun run build:e2b) for isolated testing and deployment. - Client library and example scripts (
@dzhng/claude-agent) to simplify integration. - Local deployment support with environment configuration, Docker scripts, and test clients.
Use Cases
Suitable for applications that need to expose Claude capabilities via a real-time API, such as interactive assistants, demo consoles, education labs, or sandboxed integration tests. Developers can test locally at <http://localhost:3000> or create isolated sandboxes for safe validation and CI workflows.
Technical Features
The project is implemented in TypeScript with a modular design, using a message-queue style processing and single-connection concurrency strategy to manage streamable SDK interactions and support interrupts. Its modularity allows swapping SDK backends, extending tool integrations, and integrating with CI/CD pipelines for reproducible workflows.
