VMware Monitor

English | 中文

Read-only VMware vCenter/ESXi monitoring tool. Code-level enforced safety — no destructive operations exist in this codebase.

Why a separate repository? VMware Monitor is fully independent from VMware-AIops. Safety is enforced at the code level: no power off, delete, create, reconfigure, snapshot-create/revert/delete, clone, or migrate functions exist in this codebase. Not just prompt constraints — zero destructive code paths.

Quick Install (Recommended)

Works with Claude Code, Cursor, Codex, Gemini CLI, Trae, and 30+ AI agents:

# Via Skills.sh
npx skills add zw008/VMware-Monitor

# Via ClawHub
clawhub install vmware-monitor

Claude Code Plugin Install

# Add marketplace
/plugin marketplace add zw008/VMware-Monitor

# Install plugin
/plugin install vmware-monitor

# Use the skill
/vmware-monitor:vmware-monitor

What's NOT Included (By Design)

These operations do not exist in this repository:

• ❌ Power on/off, reset, suspend VMs
• ❌ Create, delete, reconfigure VMs
• ❌ Create, revert, delete snapshots
• ❌ Clone or migrate VMs
• ❌ _double_confirm, _show_state_preview, _validate_vm_params

For these operations, use the full VMware-AIops repository.

MCP Server Integrations

The vmware-monitor MCP server works with any MCP-compatible agent or tool. Ready-to-use configuration templates are in examples/mcp-configs/. All 8 tools are read-only — code-level enforced safety.

Agent / Tool	Local Model Support	Config Template
Goose	✅ Ollama, LM Studio	goose.json
LocalCowork	✅ Fully offline	localcowork.json
mcp-agent	✅ Ollama, vLLM	mcp-agent.yaml
VS Code Copilot	—	.vscode/mcp.json
Cursor	—	cursor.json
Continue	✅ Ollama	continue.yaml
Claude Code	—	claude-code.json

Fully local operation (no cloud API required):

# Aider + Ollama + vmware-monitor (via AGENTS.md)
aider --conventions codex-skill/AGENTS.md --model ollama/qwen2.5-coder:32b

# Any MCP agent + local model + vmware-monitor MCP server
# See examples/mcp-configs/ for your agent's config format

Installation

Step 0: Prerequisites

# Python 3.10+ required
python3 --version

# Node.js 18+ required for Gemini CLI and Codex CLI
node --version

Step 1: Clone & Install Python Backend

git clone https://github.com/zw008/VMware-Monitor.git
cd VMware-Monitor
python3 -m venv .venv
source .venv/bin/activate
pip install -e .

Step 2: Configure

mkdir -p ~/.vmware-monitor
cp config.example.yaml ~/.vmware-monitor/config.yaml
# Edit config.yaml with your vCenter/ESXi targets

Set passwords via .env file (recommended):

cp .env.example ~/.vmware-monitor/.env
chmod 600 ~/.vmware-monitor/.env
# Edit and fill in your passwords

Security note: Prefer .env file over command-line export to avoid passwords appearing in shell history. config.yaml stores only hostnames, ports, and a reference to the .env file — it does not contain passwords or tokens. All secrets are stored exclusively in .env (chmod 600). Webhook notifications are disabled by default; when enabled, payloads contain no credentials, IPs, or PII — only aggregated alert metadata sent to user-configured URLs only. We recommend using a least-privilege read-only vCenter service account.

Password environment variable naming convention:

VMWARE_{TARGET_NAME_UPPER}_PASSWORD
# Replace hyphens with underscores, UPPERCASE
# Example: target "home-esxi" → VMWARE_HOME_ESXI_PASSWORD
# Example: target "prod-vcenter" → VMWARE_PROD_VCENTER_PASSWORD

Step 3: Connect Your AI Tool

Choose one (or more) of the following:

---

Option A: Claude Code (Marketplace)

Method 1: Marketplace (recommended)

In Claude Code, run:

/plugin marketplace add zw008/VMware-Monitor
/plugin install vmware-monitor

Then use:

/vmware-monitor:vmware-monitor
> Show me all VMs on esxi-lab.example.com

Method 2: Local install

# Clone and symlink
git clone https://github.com/zw008/VMware-Monitor.git
ln -sf $(pwd)/VMware-Monitor ~/.claude/plugins/marketplaces/vmware-monitor

# Register marketplace
python3 -c "
import json, pathlib
f = pathlib.Path.home() / '.claude/plugins/known_marketplaces.json'
d = json.loads(f.read_text()) if f.exists() else {}
d['vmware-monitor'] = {
    'source': {'source': 'github', 'repo': 'zw008/VMware-Monitor'},
    'installLocation': str(pathlib.Path.home() / '.claude/plugins/marketplaces/vmware-monitor')
}
f.write_text(json.dumps(d, indent=2))
"

# Enable plugin
python3 -c "
import json, pathlib
f = pathlib.Path.home() / '.claude/settings.json'
d = json.loads(f.read_text()) if f.exists() else {}
d.setdefault('enabledPlugins', {})['vmware-monitor@vmware-monitor'] = True
f.write_text(json.dumps(d, indent=2))
"

Restart Claude Code, then:

/vmware-monitor:vmware-monitor

---

Option B: Gemini CLI

# Install Gemini CLI
npm install -g @google/gemini-cli

# Install the extension from the cloned repo
gemini extensions install ./gemini-extension

# Or install directly from GitHub
# gemini extensions install https://github.com/zw008/VMware-Monitor

Then start Gemini CLI:

gemini
> Show me all VMs on my ESXi host

---

Option C: OpenAI Codex CLI

# Install Codex CLI
npm i -g @openai/codex
# Or on macOS:
# brew install --cask codex

# Copy skill to Codex skills directory
mkdir -p ~/.codex/skills/vmware-monitor
cp codex-skill/SKILL.md ~/.codex/skills/vmware-monitor/SKILL.md

# Copy AGENTS.md to project root
cp codex-skill/AGENTS.md ./AGENTS.md

Then start Codex CLI:

codex --enable skills
> List all VMs on my ESXi

---

Option D: Aider (supports local models)

# Install Aider
pip install aider-chat

# Install Ollama for local models (optional)
# macOS:
brew install ollama
ollama pull qwen2.5-coder:32b

# Run with cloud API
aider --conventions codex-skill/AGENTS.md

# Or with local model via Ollama
aider --conventions codex-skill/AGENTS.md \
  --model ollama/qwen2.5-coder:32b

---

Option E: Continue CLI (supports local models)

# Install Continue CLI
npm i -g @continuedev/cli

# Copy rules file
mkdir -p .continue/rules
cp codex-skill/AGENTS.md .continue/rules/vmware-monitor.md

Configure ~/.continue/config.yaml for local model:

models:
  - name: local-coder
    provider: ollama
    model: qwen2.5-coder:32b

Then:

cn
> Check ESXi health and alarms

---

Option F: Trae IDE

Copy the rules file to your project's .trae/rules/ directory:

mkdir -p .trae/rules
cp trae-rules/project_rules.md .trae/rules/project_rules.md

Trae IDE's Builder Mode reads .trae/rules/ Markdown files at startup.

Note: You can also install Claude Code extension in Trae IDE and use .claude/skills/ format directly.

---

Option G: Kimi Code CLI

# Copy skill file to Kimi skills directory
mkdir -p ~/.kimi/skills/vmware-monitor
cp kimi-skill/SKILL.md ~/.kimi/skills/vmware-monitor/SKILL.md

---

Option H: MCP Server (Smithery / Glama / Claude Desktop)

The MCP server exposes VMware read-only monitoring as tools via the Model Context Protocol. Works with any MCP-compatible client (Claude Desktop, Cursor, etc.).

# Run directly
python -m mcp_server

# Or via the installed entry point
vmware-monitor-mcp

# With a custom config path
VMWARE_MONITOR_CONFIG=/path/to/config.yaml python -m mcp_server

Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "vmware-monitor": {
      "command": "python",
      "args": ["-m", "mcp_server"],
      "env": {
        "VMWARE_MONITOR_CONFIG": "/path/to/config.yaml"
      }
    }
  }
}

Install via Smithery:

npx -y @smithery/cli install @zw008/VMware-Monitor --client claude

---

Option I: Standalone CLI (no AI)

# Already installed in Step 1
source .venv/bin/activate

vmware-monitor inventory vms --target home-esxi
vmware-monitor health alarms --target home-esxi
vmware-monitor vm info my-vm --target home-esxi

---

Repository	Description	Install
VMware-Monitor (this repo)	Read-only monitoring — code-level safety	clawhub install vmware-monitor
VMware-AIops	Full operations — monitoring + VM lifecycle	clawhub install vmware-aiops

Choosing between them: Use VMware-Monitor if you only need read-only monitoring with zero risk of accidental changes. Use VMware-AIops if you need full operations (create, delete, power, snapshot, clone, migrate).
