Implementation Reference

• src/tools/simulator.ts:597-628 (handler)

  The main handler function for the 'set_simulator_location' tool. It performs parameter validation and delegates to the shared executeSimctlCommandAndRespond helper to run the 'xcrun simctl location set LAT,LON' command.
  async (params: { simulatorUuid: string; latitude: number; longitude: number; }): Promise<ToolResponse> => { const extraValidation = (): ToolResponse | null => { const latitudeValidation = validateRequiredParam('latitude', params.latitude); if (!latitudeValidation.isValid) { return latitudeValidation.errorResponse!; } const longitudeValidation = validateRequiredParam('longitude', params.longitude); if (!longitudeValidation.isValid) { return longitudeValidation.errorResponse!; } return null; }; log( 'info', `Setting simulator ${params.simulatorUuid} location to ${params.latitude},${params.longitude}`, ); return executeSimctlCommandAndRespond( params, ['location', params.simulatorUuid, 'set', `${params.latitude},${params.longitude}`], 'Set Simulator Location', `Successfully set simulator ${params.simulatorUuid} location to ${params.latitude},${params.longitude}`, 'Failed to set simulator location', 'set simulator location', extraValidation, ); },
• src/tools/simulator.ts:590-596 (schema)

  Zod input schema defining parameters for the tool: simulatorUuid (string), latitude (number), longitude (number).
  { simulatorUuid: z .string() .describe('UUID of the simulator to use (obtained from list_simulators)'), latitude: z.number().describe('The latitude for the custom location.'), longitude: z.number().describe('The longitude for the custom location.'), },
• src/tools/simulator.ts:586-630 (registration)

  The registerSetSimulatorLocationTool function that calls server.tool to register the MCP tool with its name, description, schema, and handler.
  export function registerSetSimulatorLocationTool(server: McpServer): void { server.tool( 'set_simulator_location', 'Sets a custom GPS location for the simulator.', { simulatorUuid: z .string() .describe('UUID of the simulator to use (obtained from list_simulators)'), latitude: z.number().describe('The latitude for the custom location.'), longitude: z.number().describe('The longitude for the custom location.'), }, async (params: { simulatorUuid: string; latitude: number; longitude: number; }): Promise<ToolResponse> => { const extraValidation = (): ToolResponse | null => { const latitudeValidation = validateRequiredParam('latitude', params.latitude); if (!latitudeValidation.isValid) { return latitudeValidation.errorResponse!; } const longitudeValidation = validateRequiredParam('longitude', params.longitude); if (!longitudeValidation.isValid) { return longitudeValidation.errorResponse!; } return null; }; log( 'info', `Setting simulator ${params.simulatorUuid} location to ${params.latitude},${params.longitude}`, ); return executeSimctlCommandAndRespond( params, ['location', params.simulatorUuid, 'set', `${params.latitude},${params.longitude}`], 'Set Simulator Location', `Successfully set simulator ${params.simulatorUuid} location to ${params.latitude},${params.longitude}`, 'Failed to set simulator location', 'set simulator location', extraValidation, ); }, ); }
• src/tools/simulator.ts:500-557 (helper)

  Shared helper function executeSimctlCommandAndRespond used by the handler to execute the xcrun simctl command and handle responses.
  async function executeSimctlCommandAndRespond( params: { simulatorUuid: string; [key: string]: unknown }, simctlSubCommand: string[], operationDescriptionForXcodeCommand: string, successMessage: string, failureMessagePrefix: string, operationLogContext: string, extraValidation?: () => ToolResponse | null, ): Promise<ToolResponse> { const simulatorUuidValidation = validateRequiredParam( 'simulatorUuid', params.simulatorUuid as string, ); if (!simulatorUuidValidation.isValid) { return simulatorUuidValidation.errorResponse!; } if (extraValidation) { const validationResult = extraValidation(); if (validationResult) { return validationResult; } } try { const command = ['xcrun', 'simctl', ...simctlSubCommand]; const result = await executeCommand(command, operationDescriptionForXcodeCommand); if (!result.success) { const fullFailureMessage = `${failureMessagePrefix}: ${result.error}`; log( 'error', `${fullFailureMessage} (operation: ${operationLogContext}, simulator: ${params.simulatorUuid})`, ); return { content: [{ type: 'text', text: fullFailureMessage }], }; } log( 'info', `${successMessage} (operation: ${operationLogContext}, simulator: ${params.simulatorUuid})`, ); return { content: [{ type: 'text', text: successMessage }], }; } catch (error) { const errorMessage = error instanceof Error ? error.message : String(error); const fullFailureMessage = `${failureMessagePrefix}: ${errorMessage}`; log( 'error', `Error during ${operationLogContext} for simulator ${params.simulatorUuid}: ${errorMessage}`, ); return { content: [{ type: 'text', text: fullFailureMessage }], }; } }
• src/utils/register-tools.ts:339-342 (registration)

  High-level tool registration entry in the toolRegistrations array, which conditionally calls registerSetSimulatorLocationTool based on environment variable.
  register: registerSetSimulatorLocationTool, groups: [ToolGroup.SIMULATOR_MANAGEMENT], envVar: 'XCODEBUILDMCP_TOOL_SET_SIMULATOR_LOCATION', },
