A VMware ESXi/vCenter management server based on [MCP (Model Context Protocol)](https://modelcontextprotocol.io), enabling AI assistants like Claude, Gemini, GPT, and others to directly manage virtual machines via stdio JSON-RPC.

## Features

- **stdio transport** for direct AI assistant integration (Claude Desktop, Cursor, Gemini, etc.)
- ESXi and vCenter Server connections
- API key authentication
- Complete virtual machine lifecycle management
- Real-time performance monitoring
- SSL/TLS secure connection support
- Flexible configuration (YAML/JSON/Environment Variables)
