MCP Server for iOS Simulator

Implementation Reference

• src/mcp/mcp-server.ts:735-760 (registration)

  Registration of the 'list-simulator-sessions' MCP tool, including empty input schema and inline handler function that retrieves sessions via simulatorManager.getAllSessions() and returns them as JSON text.

  this.server.tool(
    'list-simulator-sessions',
    {},
    async () => {
      fileLogger.info('Listing all simulator sessions');
      try {
        const sessions = simulatorManager.getAllSessions();
        
        return {
          content: [{
            type: 'text',
            text: JSON.stringify(sessions)
          }]
        };
      } catch (error) {
        fileLogger.error('Failed to list simulator sessions', { error });
        return {
          content: [{
            type: 'text',
            text: `Error: ${error instanceof Error ? error.message : String(error)}`
          }],
          isError: true
        };
      }
    }
  );

• src/mcp/mcp-server.ts:735-760 (handler)

  The inline async handler function that executes the tool logic: logs the action, calls simulatorManager.getAllSessions(), stringifies the result, and returns it in MCP content format, with error handling.

  this.server.tool(
    'list-simulator-sessions',
    {},
    async () => {
      fileLogger.info('Listing all simulator sessions');
      try {
        const sessions = simulatorManager.getAllSessions();
        
        return {
          content: [{
            type: 'text',
            text: JSON.stringify(sessions)
          }]
        };
      } catch (error) {
        fileLogger.error('Failed to list simulator sessions', { error });
        return {
          content: [{
            type: 'text',
            text: `Error: ${error instanceof Error ? error.message : String(error)}`
          }],
          isError: true
        };
      }
    }
  );

• src/simulator/simulator-manager.ts:290-295 (helper)

  Core helper method getAllSessions() that returns an array of all active SimulatorSession objects from the internal Map<string, SimulatorSession> sessions.

  /**
   * Gets all simulator sessions
   */
  getAllSessions(): SimulatorSession[] {
    return Array.from(this.sessions.values());
  }
