Implementation Reference

• src/tools/docker.ts:261-264 (handler)

  Main handler function for 'docker_inspect' tool. Executes 'docker inspect' command with optional type flag using the shared executeDockerCommand helper.

  export async function dockerInspect(args: z.infer<typeof dockerInspectSchema>): Promise<ToolResponse> {
    const typeFlag = args.type ? `--type ${args.type}` : '';
    return executeDockerCommand(`docker inspect ${typeFlag} ${args.target}`.trim(), args.cwd);
  }

• src/tools/docker.ts:131-135 (schema)

  Zod schema used for input validation in the dispatch handler.

  export const dockerInspectSchema = z.object({
    target: z.string().describe('Container, image, network, or volume name/ID'),
    type: z.enum(['container', 'image', 'network', 'volume']).optional().describe('Type of object to inspect'),
    cwd: z.string().optional().describe('Working directory')
  });

• src/index.ts:467-470 (registration)

  Dispatch logic in main server handler that routes 'docker_inspect' calls to the dockerInspect function after schema validation.

  if (name === 'docker_inspect') {
    const validated = dockerInspectSchema.parse(args);
    return await dockerInspect(validated);
  }

• src/tools/docker.ts:466-478 (registration)

  MCP tool registration definition included in dockerTools array for listTools endpoint.

  {
    name: 'docker_inspect',
    description: 'Return low-level information on Docker objects (containers, images, networks, volumes)',
    inputSchema: {
      type: 'object',
      properties: {
        target: { type: 'string', description: 'Container, image, network, or volume name/ID' },
        type: { type: 'string', enum: ['container', 'image', 'network', 'volume'], description: 'Type of object to inspect' },
        cwd: { type: 'string', description: 'Working directory' }
      },
      required: ['target']
    }
  },

• src/tools/docker.ts:21-62 (helper)

  Shared helper function that executes docker commands via child_process.exec and formats ToolResponse.

  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
      };
    }
  }
