Implementation Reference

• src/tools/docker.ts:249-253 (handler)

  The main handler function for the docker_stop tool that constructs and executes the 'docker stop' command via the executeDockerCommand helper.
  export async function dockerStop(args: z.infer<typeof dockerStopSchema>): Promise<ToolResponse> { const containers = Array.isArray(args.containers) ? args.containers.join(' ') : args.containers; const timeoutFlag = args.timeout ? `-t ${args.timeout}` : ''; return executeDockerCommand(`docker stop ${timeoutFlag} ${containers}`.trim(), args.cwd); }
• src/tools/docker.ts:119-123 (schema)

  Zod input validation schema for the docker_stop tool.
  export const dockerStopSchema = z.object({ containers: z.union([z.string(), z.array(z.string())]).describe('Container name(s) or ID(s)'), timeout: z.number().optional().describe('Seconds to wait before killing container'), cwd: z.string().optional().describe('Working directory') });
• src/tools/docker.ts:428-446 (registration)

  MCP tool registration definition in dockerTools array (used for tool listing), including name, description, and JSON input schema.
  { name: 'docker_stop', description: 'Stop one or more running containers', inputSchema: { type: 'object', properties: { containers: { oneOf: [ { type: 'string' }, { type: 'array', items: { type: 'string' } } ], description: 'Container name(s) or ID(s)' }, timeout: { type: 'number', description: 'Seconds to wait before killing container' }, cwd: { type: 'string', description: 'Working directory' } }, required: ['containers'] } },
• src/index.ts:459-462 (registration)

  Dispatch/registration logic in the main CallToolRequest handler that validates arguments with dockerStopSchema and calls the dockerStop handler function.
  if (name === 'docker_stop') { const validated = dockerStopSchema.parse(args); return await dockerStop(validated); }
• src/tools/docker.ts:21-62 (helper)

  Shared helper function used by all Docker tools (including dockerStop) to execute docker 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 }; } }
