dsh-config-center

Managing plugins, skills, and MCP servers in DeepSeek Harness has traditionally meant juggling CLI commands and hand-editing YAML files — a flow that is easy to get wrong and hard to audit. dsh-config-center solves this by embedding a zero-intrusion Extension Center panel right in the dsh WebUI sidebar, so every extension lifecycle operation can be completed in the browser without touching the terminal or the dsh source tree.

The panel exposes three tabs. The Plugins tab lets you install, remove, or edit bundle plugins by name@version, local path, or GitHub reference, and visually add, modify, disable, or delete logical rows in cordis.patch.yml. The Skills tab aggregates multi-root directory scans, toggles model-visible and user-invocable frontmatter flags, and provides full SKILL.md editing with hash-fenced saves that hot-apply through the built-in watcher. The MCP tab supports adding, editing, disabling, and removing both stdio and streamable-http servers, with a live connection badge and a one-click probe. Plugin changes require a single profile restart; skills and MCP servers take effect the moment you save.

If you run multiple plugins, custom skills, and external MCP tools under the dsh web profile and want to stop switching between a terminal and config editors, Extension Center is built for you. It modifies nothing in the dsh source, ships every runtime peer from the dsh host install itself, and leaves a completely clean state the moment you uninstall it.
