dsh-api

DeepSeek Harness (dsh) runs locally with internal services that are difficult for external processes to access directly. The dsh-api plugin solves this by exposing an HTTP interface on the machine's loopback address (127.0.0.1). It allows any desktop wrapper, browser extension, or CLI running on the same machine to control dsh through a unified entry point, without needing to reach into its internal in-process services.

The plugin features a two-layer API architecture. The native layer handles health checks, language preferences, workspace management, and real-time event streams via Server-Sent Events (SSE). Additionally, through a registered "companion" process, it enables advanced interactions such as injecting text, switching workspace contexts, focusing the window, reloading the interface, and quitting the host application.

This tool is ideal for developers and tool builders looking to deeply integrate dsh. For instance, desktop applications can leverage it for window control, or editor plugins can use it to inject selected text directly into AI chats. For scenarios where standard HTTP interaction is preferred over parsing internal dsh structures, dsh-api provides a secure and powerful solution.
