This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

MCP connection lifecycle management plugin for DeepSeek Harness.

Manage MCP server connections from the DSH Web GUI Settings → Plugins page, and from chat via mcp_list_connections / mcp_add_connection / mcp_remove_connection / mcp_test_connection tools. All changes persist to ~/.dsh/mcp-connections.json and survive restarts.

All reads and writes go through a single JSON file. The UI calls the HTTP endpoint; server tools write the same file. At startup, connections are restored automatically.

Installation

Option 1: dsh plugin add (recommended)

dsh plugin --profile web add github:haode01/dsh-mcp-manager

Installs into ~/.dsh/profiles/web/, auto-adds to cordis.yml as a profile bundle layer. No manual symlink or --patch needed.

Restart DSH:

dsh web

Option 2: Git clone + symlink

git clone https://github.com/haode01/dsh-mcp-manager.git /path/to/dsh-mcp-manager
ln -s /path/to/dsh-mcp-manager ~/.dsh/profiles/web/node_modules/dsh-mcp-manager
dsh web --patch /path/to/dsh-mcp-manager/cordis.patch.yml

Option 3: Cordis config

- insert:
    - id: mcp-manager
      name: 'dsh-mcp-manager'

Verify

Open Settings → Plugins — an MCP Manager card should appear. In chat, mcp_list_connections should respond.

Usage

Add from UI

1. Settings → Plugins → MCP Manager → expand card 2. Choose HTTP or Stdio tab 3. HTTP: server name + URL (optional Bearer token) 4. Stdio: server name + full command (e.g. npx -y @mozilla/firefox-devtools-mcp@latest) 5. Click Add → auto-save → auto-test → tool list with progress bar

Add from chat

> Add MCP connection http://10.118.81.110:3100/mcp/openwrt with name "openwrt"

AI calls mcp_add_connection — connection is immediately available and persisted.

Test connections

Every connection has a Test button. HTTP tests in-browser; Stdio tests via server endpoint with download progress.
