Read-only VMware vCenter/ESXi monitoring with 27 MCP tools. Code-level safety.
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.
Works with Claude Code, Cursor, Codex, Gemini CLI, Trae, and 30+ AI agents:
# Via Skills.sh
npx skills add zw008/VMware-Monitor
# Via ClawHub

| Feature | Details |
|---|---|
| Code-Level Isolation | Independent repository — zero destructive functions in codebase |
| Audit Trail | All queries logged to ~/.vmware-monitor/audit.log (JSONL) |
| Password Protection | .env file loading with permission check (warn if not 600) |
| SSL Self-signed Support | disableSslCertValidation — only for ESXi with self-signed certs in isolated labs; production should use CA-signed certificates |
| Prompt Injection Protection | vSphere event messages and host logs are truncated, sanitized, and wrapped in boundary markers |
| Webhook Data Scope | Sends monitoring summaries to user-configured URLs only — no third-party services by default |
| Production Recommended | AI agents can misinterpret context and execute unintended destructive operations — real-world incidents have shown AI-driven tools deleting production databases and entire environments. VMware-Monitor eliminates this risk: no destructive code paths exist. Use VMware-AIops only in dev/lab environments |
These operations do not exist in this repository:
_double_confirm, _show_state_preview, _validate_vm_paramsFor these operations, use the full VMware-AIops repository.

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
# Python 3.10+ required
python3 --version
# Node.js 18+ required for Gemini CLI and Codex CLI
node --version
git clone https://github.com/zw008/VMware-Monitor.git
cd VMware-Monitor
python3 -m venv .venv
source .venv/bin/activate
pip install -e .
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
.envfile over command-lineexportto avoid passwords appearing in shell history.config.yamlstores only hostnames, ports, and a reference to the.envfile — 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
Choose one (or more) of the following:
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
# 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
# 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
# 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
# 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
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.
# Copy skill file to Kimi skills directory
mkdir -p ~/.kimi/skills/vmware-monitor
cp kimi-skill/SKILL.md ~/.kimi/skills/vmware-monitor/SKILL.md
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
# 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).
If you encounter any errors or issues, please send the error message, logs, or screenshots to zhouwei008@gmail.com. Contributions are welcome!
