Implementation Reference

• src/services/DockerService.ts:1035-1081 (handler)

  The systemOperations method that handles the 'docker_system' tool logic. It builds and executes docker system commands (info, version, events, df, prune) based on the action argument.

  async systemOperations(args: DockerSystemArgs): Promise<ToolResult> {
    const { action, all, volumes, filter, force, since, until, format } = args;
  
    ValidationUtils.validateRequired({ action }, ['action']);
  
    let command = 'docker system';
  
    switch (action) {
      case 'info':
        command = 'docker system info';
        if (format) command += ` --format ${format}`;
        break;
        
      case 'version':
        command = 'docker version';
        if (format) command += ` --format ${format}`;
        break;
        
      case 'events':
        command = 'docker system events';
        if (since) command += ` --since ${since}`;
        if (until) command += ` --until ${until}`;
        if (filter) command += ` --filter ${filter}`;
        break;
        
      case 'df':
        command = 'docker system df';
        break;
        
      case 'prune':
        command = 'docker system prune';
        if (all) command += ' -a';
        if (volumes) command += ' --volumes';
        if (force) command += ' -f';
        if (filter) command += ` --filter ${filter}`;
        break;
        
      default:
        throw new Error(`Unsupported system action: ${action}`);
    }
  
    try {
      return await this.executeDockerCommand(command, { cwd: this.getCurrentWorkspace() });
    } catch (error: any) {
      throw new Error(`Docker system ${action} failed: ${error.message}`);
    }
  }

• src/services/DockerService.ts:169-178 (schema)

  The DockerSystemArgs interface defining the input schema for the docker_system tool, with action as a union type of 'info' | 'version' | 'events' | 'df' | 'prune' and optional parameters.

  export interface DockerSystemArgs {
    action: 'info' | 'version' | 'events' | 'df' | 'prune';
    all?: boolean;
    volumes?: boolean;
    filter?: string;
    force?: boolean;
    since?: string;
    until?: string;
    format?: string;
  }

• src/index.ts:219-220 (registration)

  The router case statement that dispatches the 'docker_system' tool to systemOperations on the DockerService.

  case 'docker_system':
    return await this.dockerService.systemOperations(args as DockerSystemArgs);

• src/toolDefinitions.ts:570-587 (registration)

  The tool definition/registration for 'docker_system', declaring the name, description, and inputSchema with properties like action, all, volumes, force.

  {
    name: 'docker_system',
    description: 'Docker system operations and information',
    inputSchema: {
      type: 'object',
      properties: {
        action: { 
          type: 'string', 
          enum: ['info', 'version', 'events', 'df', 'prune'],
          description: 'System action to perform' 
        },
        all: { type: 'boolean', description: 'Apply to all resources (for prune)' },
        volumes: { type: 'boolean', description: 'Include volumes in operation' },
        force: { type: 'boolean', description: 'Force operation without confirmation' },
      },
      required: ['action'],
    },
  },
