• src/tools/app_path.ts:49-180 (handler)

  Core handler logic shared across app path tools. Uses xcodebuild -showBuildSettings to retrieve BUILT_PRODUCTS_DIR and FULL_PRODUCT_NAME to construct the app bundle path.

• src/tools/app_path.ts:315-349 (registration)

  Tool registration function that registers 'get_sim_app_path_name_ws' with the MCP server, defines input schema, and provides handler wrapper calling the core logic.
  export function registerGetSimulatorAppPathByNameWorkspaceTool(server: McpServer): void { type Params = BaseWorkspaceParams & BaseAppPathSimulatorNameParams; registerTool<Params>( server, 'get_sim_app_path_name_ws', "Gets the app bundle path for a simulator by name using a workspace. IMPORTANT: Requires workspacePath, scheme, platform, and simulatorName. Example: get_sim_app_path_name_ws({ workspacePath: '/path/to/workspace', scheme: 'MyScheme', platform: 'iOS Simulator', simulatorName: 'iPhone 16' })", { workspacePath: workspacePathSchema, scheme: schemeSchema, platform: platformSimulatorSchema, simulatorName: simulatorNameSchema, configuration: configurationSchema, useLatestOS: useLatestOSSchema, }, async (params: Params) => { const workspaceValidation = validateRequiredParam('workspacePath', params.workspacePath); if (!workspaceValidation.isValid) return workspaceValidation.errorResponse!; const schemeValidation = validateRequiredParam('scheme', params.scheme); if (!schemeValidation.isValid) return schemeValidation.errorResponse!; const platformValidation = validateRequiredParam('platform', params.platform); if (!platformValidation.isValid) return platformValidation.errorResponse!; const simulatorNameValidation = validateRequiredParam('simulatorName', params.simulatorName); if (!simulatorNameValidation.isValid) return simulatorNameValidation.errorResponse!; return _handleGetAppPathLogic({ ...params, configuration: params.configuration ??

• src/tools/app_path.ts:321-328 (schema)

  Input schema definition for the tool parameters using Zod schemas from common.ts
  { workspacePath: workspacePathSchema, scheme: schemeSchema, platform: platformSimulatorSchema, simulatorName: simulatorNameSchema, configuration: configurationSchema, useLatestOS: useLatestOSSchema, },
• src/utils/register-tools.ts:286-292 (registration)

  Central tool registry entry that conditionally registers the tool based on environment variable.
  register: registerGetSimulatorAppPathByNameWorkspaceTool, groups: [ ToolGroup.IOS_SIMULATOR_WORKFLOW, ToolGroup.APP_DEPLOYMENT, ToolGroup.PROJECT_DISCOVERY, ], envVar: 'XCODEBUILDMCP_TOOL_GET_SIMULATOR_APP_PATH_BY_NAME_WORKSPACE',
