openma-ai/dsh-mcp-apps: Add MCP Apps support for DeepSeek Harness
# Foreword MCP Apps allow MCP tool results to carry `ui://` HTML resources, which are rendered by the client into an interactive interface. To get this working in DeepSeek Harness (DSH), a complete set of components is required, including the protocol Host, sandbox renderer, and display mode management. In contrast to existing approaches: DSH's Web build comes with an inline-only renderer that only covers a single surface type. Below, I introduce openma-ai/dsh-mcp-apps: it packages the MCP Apps Host and Web renderer into a standard Cordis plugin, filling in this layer of capability. # What is openma-ai/dsh-mcp-apps (npm

`@sugarforever/dsh-mcp-apps` is an MIT-licensed DeepSeek Harness (DSH) plugin designed to render MCP tools with UI resources as sandboxed interactive applications within DSH sessions, while maintaining visibility of the tools to the model.

Environment requirements include Node.js `^22.19.0` or `>=24.0.0`, installation of `pnpm`, and starting DSH Web.
