dsh-mcp-ui

Visual MCP server configuration for DeepSeek Harness: manage Model Context Protocol servers right from the DSH Web settings UI. It wires the official dsh-mcp-client plugin instances for you — save and it just works, no config files to hand-edit.

中文文档

Features

• 🖥️ Settings card UI — manage servers under Settings > Plugins > Plugin Config > MCP Servers, same card style as other DSH plugins
• 🔌 Both transports — stdio (local process) and streamable-http (remote URL)
• 📝 Full field coverage — serverName, command/args/env/cwd, url/headers, tool-call timeout, startup-failure policy, auto-reconnect (toggle / delay / cap / attempts)
• 🔄 Hot sync — saving mounts/unmounts the corresponding dsh-mcp-client instances host-side, no dsh restart needed
• 🛡️ Safe — server list lives in ~/.dsh/settings.yaml; secrets in env can be referenced as environment variables

Install

# from GitHub
dsh plugin --profile web add github:quan-v/dsh-mcp-ui

Published to npm later — once available, dsh plugin --profile web add dsh-mcp-ui also works.

Restart dsh web, then find the MCP Servers card under Settings > Plugins > Plugin Config.

Usage

1. Open the settings card, click + Add Server
2. Fill in a unique serverName (model-facing tools are named mcp__<serverName>__<tool>)
3. Pick a transport (stdio / streamable-http / SSE) and fill the matching fields
4. Click Save — the host connects automatically and the server's tools become callable by the model

Config storage

The server list lives in the mcp-ui: section of settings.yaml, sibling to other plugin settings:

mcp-ui:
  servers:
    - serverName: github
      transport: stdio
      command: npx
      args:
        - -y
        - '@modelcontextprotocol/server-github'
      env:
        GITHUB_TOKEN: ${GITHUB_TOKEN}
      toolCallTimeoutMs: 60000
      failOnStartupError: false
      reconnect:
        enabled: true
        initialDelayMs: 500
        maxDelayMs: 30000
        maxAttempts: 10

Relationship with dsh-mcp-client

This plugin does not implement the MCP protocol. It does two things:

1. Provides the settings card and stores your configuration in settings.yaml
2. Watches config changes host-side and mounts/unmounts @deepseek-ai/dsh-mcp-client instances via ctx.plugin()

The official dsh-mcp-client handles the actual connections, tool discovery, and mcp__server__tool naming.

Changelog

1.0.1 (2026-08-22)

• Fix: add explicit key to the settings.plugin.item slot registration. DSH 0.1.1+ requires keyed slots to declare options.key; without it the plugin fails to load with keyed slot "settings.plugin.item" requires options.key.
