In the development practice of DSH, scattered skill directories, MCP server connection configuration, and registration of local CLI tools often require manually editing multiple files. The dsh-s-m-c-center plugin provides a unified Web UI settings page, bringing the agent’s three core tool types (skills, MCP servers, and local CLI) into a single interface for management.

Plugin Overview

Maintained by YpipaQ, this plugin aims to add a settings page to the DeepSeek Harness (DSH) Web GUI. It does not require modifying DSH source code. By installing an npm package and applying a configuration patch, it enables skill browsing and toggling, session-level skill injection, actual MCP server connections, and discovery and registration of local CLI tools.

Core Features

  1. Skill Management

    • Supports browsing, enabling, and disabling skills.
    • Supports importing skills.
    • Provides a “session default” setting and assigns an independent skill set to each conversation.
    • The plugin maintains a unified skill store and does not directly touch original SKILL.md files.

  2. MCP Server Management

    • Provides forms and a JSON editor to create and modify MCP server configurations.
    • Supports toggling between active and archived states.
    • Provides a one-time connection test feature.
    • Establishes actual connections via @deepseek-ai/dsh-mcp-client, rather than merely using configuration files.

  3. Local CLI Tool Management

    • Supports discovering and probing local CLI tools.
    • Automatically registers system CLI tools.
    • Detects installation status, version numbers, subcommands, and API keys.

Installation and Activation

The installation command is as follows:

npm install dsh-s-m-c-center

After installation, go to Settings -> Web UI Plugins -> Tool Management in the DeepSeek Harness Web UI to use it.

Applicable Scenarios and Notes

  • Version Requirement: The plugin requires DeepSeek Harness version >= 0.1.2-alpha.2 and has currently been verified for compatibility up to 0.2.1-alpha.1.
  • Zero Source Modification: Installation consists of one npm package plus a single-line configuration patch, and it does not change the DSH source code structure.
  • Verification Result: The plugin has passed three rounds of external testing, with 16/16 tests successful.

Summary

dsh-s-m-c-center is a lightweight workflow plugin that resolves configuration and management challenges for three common tool types in DSH through a unified interface. It is suitable for developers who want to simplify the configuration process and centrally manage MCP servers and skill sets.
