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

Install dependencies:

pip install pyvmomi pyyaml uvicorn mcp-core

Create configuration file config.yaml:

vcenter_host: "your-vcenter-ip"
vcenter_user: "administrator@vsphere.local"
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

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

Create VM

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

Clone VM

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

Delete VM

{
    "name": "vm-name"
}

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

Production Environment:
- Use valid SSL certificates
- Enable API key authentication
- Set appropriate log levels
- Restrict API access scope
Testing Environment:
- Set insecure: true to skip SSL verification
- Use more detailed log level (DEBUG)
