UCloud MCP Server

A cloud instance management server based on MCP-Go and UCloud SDK, supporting UCloud instance management through the MCP protocol.

Features

• Query instance information
• List all instances
• Get instance status
• Monitor instance performance metrics
• MCP protocol support
• Configuration file support

Requirements

• Go 1.23 or higher
• UCloud account and API credentials

Configuration

The service supports two configuration methods:

1. Configuration File (Recommended)

Create a config.json file:

{
    "region": "cn-bj2",
    "project_id": "your-project-id",
    "public_key": "your-public-key",
    "private_key": "your-private-key"
}

2. Environment Variables

If not specified in the configuration file, the service will try to read from environment variables:

export UCLOUD_REGION="cn-bj2"        # UCloud region
export UCLOUD_PROJECT_ID="your-project-id"  # Project ID
export UCLOUD_PUBLIC_KEY="your-public-key"  # API public key
export UCLOUD_PRIVATE_KEY="your-private-key"  # API private key

Configuration priority: Configuration file > Environment variables

Installation and Running

1. Clone the repository:

git clone https://github.com/renzheng.wang/ucloud-mcp-server.git
cd ucloud-mcp-server

2. Install dependencies:

go mod download

3. Build the service:

go build -o ucloud-mcp-server

4. Run the service:

Basic usage:

./ucloud-mcp-server

With custom configuration:

./ucloud-mcp-server --config /path/to/config.json --port 8080

Available startup options:

• --config: Specify the path to your configuration file (default: ./config.json)
• --port: Specify the port to listen on (default: 8080)

Examples:

# Use custom config file
./ucloud-mcp-server --config /etc/ucloud/config.json

# Use custom port
./ucloud-mcp-server --port 9000

# Use both custom config and port
./ucloud-mcp-server --config /etc/ucloud/config.json --port 9000

The service will provide MCP protocol service through standard input/output.

Available Operations

Instance Information

Get detailed information about a specific instance, including:

• Basic instance details
• Configuration information
• Current status
• Resource allocation

Instance Status

Monitor the current operational status of any instance in real-time.

Instance Metrics

Access comprehensive monitoring metrics for instances, including:

• CPU utilization
• Disk I/O operations
• Network traffic statistics
• System performance data

Instance List

View a complete list of all available instances in your account, including their basic information and current status.

Monitoring Metrics

The system provides the following monitoring metrics:

• CPU Metrics

  • CPUUtilization: CPU usage percentage (%)

• Disk Metrics

  • IORead: Disk read rate
  • IOWrite: Disk write rate
  • DiskReadOps: Number of disk read operations
  • DiskWriteOps: Number of disk write operations

• Network Metrics

  • NICIn: Network inbound traffic (bytes/s)
  • NICOut: Network outbound traffic (bytes/s)
  • NetPacketIn: Number of inbound network packets
  • NetPacketOut: Number of outbound network packets

Important Notes

• Keep your UCloud API credentials secure
• Use configuration files or key management services for sensitive information in production environments
• All operations are performed through the MCP protocol with standard I/O support
• Monitoring data may have a few minutes delay
• Regularly check monitoring metrics to identify potential issues early
