What is OpenHarness?

OpenHarness is an open-source SDK built with TypeScript, aimed at developers who wish to craft customized AI-agent applications, including coding assistants, command-line utilities, and web-based supports. This toolkit is equipped with stateless agent execution, explicit management of conversation states, and streaming event support, as well as middleware options for retries, data persistence, and context oversight. Furthermore, it enables the creation of hierarchical subagents and tools governed by permission settings. Developers can seamlessly connect to model providers using the Vercel AI SDK, expand features through the Model Context Protocol (MCP), and employ filesystem or shell tools via adaptable providers. The SDK also provides React hooks and Vue composables, making it easier to integrate streaming agent outputs into diverse application interfaces. OpenHarness is distributed as an npm package and is tailored for projects that operate within Node.js or edge environments, functioning primarily as a developer-oriented library instead of a service intended for end-users. In addition, its design promotes both flexibility and scalability for AI application development, empowering users to customize their solutions to meet specific demands effectively. This adaptability ensures that developers can explore innovative AI applications without being constrained by rigid structures.
