dsh-api-gateway

When building AI agents with DeepSeek Harness, users typically interact through a web GUI. However, many scenarios require automated access from external applications or scripts, such as integrating into existing workflows or building multi-language clients. The dsh-api-gateway plugin addresses this by turning a running Harness instance into an HTTP API, providing standard REST and SSE endpoints that allow any HTTP-capable client to interact with agent sessions.

The plugin's core capabilities include token-by-token streaming replies via SSE for real-time feedback. It introduces workspace membership, where API sessions are automatically grouped into relevant workspaces, staying in sync with GUI sessions. Users can discover existing sessions, adopt GUI-opened sessions for live co-driving or cold resume, and achieve seamless switching. Reasoning and text replies are separated, maintaining a clear interaction history.

This plugin is particularly suited for developers who need to integrate Harness into automation pipelines, build custom frontends, or control agents from scripts. It supports multi-language clients (like Python, PowerShell, curl) and offers simple API-key authentication. For users looking to extend agent capabilities from external systems without leaving the GUI, it's an ideal choice. Note that it is not a substitute for the official Python SDK but rather a complement for live deployments.

In summary, dsh-api-gateway adds flexibility and accessibility to DeepSeek Harness, making agent capabilities easier to embed into various tech stacks. It also publishes events for other plugins to extend functionality.
