Implementation Reference

• main.py:133-162 (handler)

  The main MCP tool handler for 'list_templates', including registration via @mcp.tool() decorator. This function fetches templates from the template_manager and formats them for output.
  @mcp.tool() async def list_templates(ctx: Context, language: str | None = None) -> str: """ list available templates for MCP server creation. Args: language: Filter by language (optional) Returns: Formatted list of available templates """ try: template_manager = ctx.request_context.lifespan_context["template_manager"] templates = await template_manager.list_templates(language=language) if not templates: return "No templates available" result = "📋 Available Templates:\n\n" for lang, template_list in templates.items(): result += f"**{lang.upper()}:**\n" for template in template_list: result += f" • {template['name']}: {template['description']}\n" result += "\n" return result except Exception as e: logger.error(f"Failed to list templates: {e}") return f"❌ Error listing templates: {str(e)}"
• 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, "description": template.description, "features": template.features, }) return result
