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: "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

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

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)
