Implementation Reference

• src/index.ts:233-243 (handler)

  Handler for the 'analyze_current_auth' tool. Extracts projectPath, logs the analysis start, and returns a placeholder completion message. Actual implementation is commented as a todo.

  case "analyze_current_auth": {
    const { projectPath } = request.params.arguments as { projectPath: string };
    logger.info(`Analyzing existing auth in ${projectPath}`);
    // Implementation would detect and analyze current auth setup
    return {
      content: [{
        type: "text",
        text: `Auth analysis complete for ${projectPath}`
      }]
    };
  }

• src/index.ts:99-112 (schema)

  Tool schema definition including name, description, and inputSchema requiring 'projectPath' for the 'analyze_current_auth' tool.

    name: "analyze_current_auth",
    description: "Detect and analyze existing auth.js/next-auth implementation",
    inputSchema: {
      type: "object",
      properties: {
        projectPath: {
          type: "string",
          description: "Path to the project root"
