• src/mcp_creator/core/template_manager.py:60-78 (helper)

  Core helper method in TemplateManager that performs the actual template listing and filtering by language, returning a structured dictionary of templates.

  async def list_templates(self, language: str | None = None) -> dict[str, list[dict]]:
      """list templates with optional language filtering."""
      result = {}
  
      for template in self.templates.values():
          if language and template.language != language:
              continue
  
          lang = template.language
          if lang not in result:
              result[lang] = []
  
          result[lang].append({
              "name": template.name,
