CloudStack MCP Server

Instructions

Implementation Reference

• src/handlers/storage-handlers.ts:77-88 (handler)

  The main handler function that executes the resize_volume tool by calling the CloudStack client and formatting the response.

  async handleResizeVolume(args: any) {
    const result = await this.cloudStackClient.resizeVolume(args);
    
    return {
      content: [
        {
          type: 'text',
          text: `Resized volume ${args.id}. Job ID: ${result.resizevolumeresponse?.jobid}`
        }
      ]
    };
  }

• src/tool-definitions/storage-tools.ts:89-112 (schema)

  Defines the tool metadata including name, description, and input schema for resize_volume.

  {
    name: 'resize_volume',
    description: 'Resize a volume',
    inputSchema: {
      type: 'object',
      properties: {
        id: {
          type: 'string',
          description: 'Volume ID',
        },
        size: {
          type: 'number',
          description: 'New size in GB',
        },
        shrinkok: {
          type: 'boolean',
          description: 'Allow shrinking',
          default: false,
        },
      },
      required: ['id', 'size'],
      additionalProperties: false,
    },
  },

• src/server.ts:142-143 (registration)

  Registers the resize_volume tool in the MCP server by dispatching tool calls to the storage handler.

  case 'resize_volume':
    return await this.storageHandlers.handleResizeVolume(args);

• src/cloudstack-client.ts:176-178 (helper)

  Low-level wrapper method that sends the resizeVolume command to the CloudStack API.

  async resizeVolume(params: CloudStackParams): Promise<CloudStackResponse> {
    return this.request('resizeVolume', params);
  }
