Implementation Reference

• src/tools/docker.ts:309-319 (handler)

  The main handler function that constructs and executes the 'docker compose down' command with options for volumes, orphans, compose file, and working directory.

  export async function dockerComposeDown(args: z.infer<typeof dockerComposeDownSchema>): Promise<ToolResponse> {
    const volumesFlag = args.volumes ? '-v' : '';
    const orphansFlag = args.removeOrphans ? '--remove-orphans' : '';
    const fileFlag = args.file ? `-f ${args.file}` : '';
    const composeCmd = await getComposeCmd();
  
    return executeDockerCommand(
      `${composeCmd} ${fileFlag} down ${volumesFlag} ${orphansFlag}`.trim(),
      args.cwd
    );
  }

• src/tools/docker.ts:168-173 (schema)

  Zod schema used for runtime input validation of the docker_compose_down tool parameters.

  export const dockerComposeDownSchema = z.object({
    volumes: z.boolean().optional().default(false).describe('Remove named volumes'),
    removeOrphans: z.boolean().optional().default(false).describe('Remove containers for services not in compose file'),
    file: z.string().optional().describe('Path to compose file'),
    cwd: z.string().optional().describe('Working directory')
  });

• src/tools/docker.ts:536-548 (registration)

  MCP tool definition/registration in the dockerTools array, including JSON schema for tool listing.

  {
    name: 'docker_compose_down',
    description: 'Stop and remove containers, networks created by docker-compose up',
    inputSchema: {
      type: 'object',
      properties: {
        volumes: { type: 'boolean', default: false, description: 'Remove named volumes' },
        removeOrphans: { type: 'boolean', default: false, description: 'Remove containers for services not in compose file' },
        file: { type: 'string', description: 'Path to compose file' },
        cwd: { type: 'string', description: 'Working directory' }
      }
    }
  },

• src/index.ts:487-489 (registration)

  Runtime dispatch/registration in the main CallToolRequest handler that routes calls to the dockerComposeDown function after schema validation.

  if (name === 'docker_compose_down') {
    const validated = dockerComposeDownSchema.parse(args);
    return await dockerComposeDown(validated);

• src/tools/docker.ts:21-62 (helper)

  Core helper function used by all Docker tools, including dockerComposeDown, to execute shell commands and format responses.

  async function executeDockerCommand(command: string, cwd?: string): Promise<ToolResponse> {
    try {
      const { stdout, stderr } = await execAsync(command, {
        cwd: cwd || process.cwd(),
        shell: '/bin/bash',
        maxBuffer: 10 * 1024 * 1024, // 10MB buffer for logs
        timeout: 60000 // 60 second timeout for builds
      });
  
      return {
        content: [
          {
            type: "text" as const,
            text: JSON.stringify({
              success: true,
              command: command,
              stdout: stdout.trim(),
              stderr: stderr.trim(),
              cwd: cwd || process.cwd()
            }, null, 2)
          }
        ]
      };
    } catch (error: any) {
      return {
        content: [
          {
            type: "text" as const,
            text: JSON.stringify({
              success: false,
              command: command,
              stdout: error.stdout?.trim() || '',
              stderr: error.stderr?.trim() || error.message,
              exitCode: error.code || 1,
              cwd: cwd || process.cwd()
            }, null, 2)
          }
        ],
        isError: true
      };
    }
  }
