Implementation Reference

src/index.ts:247-268 (handler)

The main handler function that implements the list_better_auth_features tool logic. It checks the cache for features list, loads from docs if needed, filters by optional category, and returns the results in a standardized response.

private async handleListFeatures(args?: any) {
  try {
    if (!this.featuresListCache) {
      await this.loadFeaturesFromDocs();
    }
    
    let features = this.featuresListCache || [];
    
    // Filter by category if specified
    if (args?.category) {
      features = features.filter(feature => feature.category === args.category);
    }
    
    return this.createSuccessResponse({
      total: features.length,
      features: features,
      categories: Object.keys(this.FEATURE_CATEGORIES),
    });
  } catch (error) {
    this.handleAxiosError(error, "Failed to fetch Better Auth features");
  }
}
