SpringBrand DeepSeek Harness - An independent guide to DSH

SpringBrand DeepSeek Harness is an open-source OAuth 2.1 MCP client plugin for DeepSeek Harness (dsh). It enables dsh to connect to MCP servers that require authentication through a browser-based OAuth flow.

The plugin supports PKCE, dynamic client registration, local callback handling, persistent credential storage, reconnects, and MCP tool discovery and execution. It also includes a preconfigured connection to the SpringBrand marketplace, so developers can authorize once and use SpringBrand capabilities directly in DeepSeek Harness.
