ESXi MCP Server

ESXi MCP Server

A VMware ESXi/vCenter management server based on MCP (Model Control Protocol), providing simple REST API interfaces for virtual machine management.

Features

• Support for ESXi and vCenter Server connections
• Real-time communication based on SSE (Server-Sent Events)
• RESTful API interface with JSON-RPC support
• API key authentication
• Complete virtual machine lifecycle management
• Real-time performance monitoring
• SSL/TLS secure connection support
• Flexible configuration options (YAML/JSON/Environment Variables)

Core Functions

• Virtual Machine Management
  • Create VM
  • Clone VM
  • Delete VM
  • Power On/Off operations
  • List all VMs
• Performance Monitoring
  • CPU usage
  • Memory usage
  • Storage usage
  • Network traffic statistics

Requirements

• Python 3.7+
• pyVmomi
• PyYAML
• uvicorn
• mcp-core (Machine Control Protocol core library)

Quick Start

1. Install dependencies:

pip install pyvmomi pyyaml uvicorn mcp-core

2. Create configuration file config.yaml:

vcenter_host: "your-vcenter-ip"
vcenter_user: "[email protected]"
vcenter_password: "your-password"
datacenter: "your-datacenter"        # Optional
cluster: "your-cluster"              # Optional
datastore: "your-datastore"          # Optional
network: "VM Network"                # Optional
insecure: true                       # Skip SSL certificate verification
api_key: "your-api-key"             # API access key
log_file: "./logs/vmware_mcp.log"   # Log file path
log_level: "INFO"                    # Log level

3. Run the server:

python server.py -c config.yaml

API Interface

Authentication

All privileged operations require authentication first:

POST /sse/messages
Authorization: Bearer your-api-key

Main Tool Interfaces

1. Create VM

{
    "name": "vm-name",
    "cpu": 2,
    "memory": 4096,
    "datastore": "datastore-name",
    "network": "network-name"
}

2. Clone VM

{
    "template_name": "source-vm",
    "new_name": "new-vm-name"
}

3. Delete VM

{
    "name": "vm-name"
}

4. Power Operations

{
    "name": "vm-name"
}

Resource Monitoring Interface

Get VM performance data:

GET vmstats://{vm_name}

Configuration

Parameter	Description	Required	Default
vcenter_host	vCenter/ESXi server address	Yes	-
vcenter_user	Login username	Yes	-
vcenter_password	Login password	Yes	-
datacenter	Datacenter name	No	Auto-select first
cluster	Cluster name	No	Auto-select first
datastore	Storage name	No	Auto-select largest available
network	Network name	No	VM Network
insecure	Skip SSL verification	No	false
api_key	API access key	No	-
log_file	Log file path	No	Console output
log_level	Log level	No	INFO

Environment Variables

All configuration items support environment variable settings, following these naming rules:

• VCENTER_HOST
• VCENTER_USER
• VCENTER_PASSWORD
• VCENTER_DATACENTER
• VCENTER_CLUSTER
• VCENTER_DATASTORE
• VCENTER_NETWORK
• VCENTER_INSECURE
• MCP_API_KEY
• MCP_LOG_FILE
• MCP_LOG_LEVEL

Security Recommendations

1. Production Environment:

   • Use valid SSL certificates
   • Enable API key authentication
   • Set appropriate log levels
   • Restrict API access scope

2. Testing Environment:

   • Set insecure: true to skip SSL verification
   • Use more detailed log level (DEBUG)
