Implementation Reference

• src/mcts_mcp_server/server.py:462-489 (handler)

  The core handler function that implements the 'list_available_models' tool logic. It returns a hardcoded list of available Gemini models based on the provider parameter.

  def list_available_models(provider: str = "gemini") -> dict[str, Any]:
      """
      List available models for a given provider.
  
      Args:
          provider: Provider name to list models for (currently only 'gemini' supported)
  
      Returns:
          Dict containing available models, default model, and current configuration
  
      Note:
          Model availability depends on the provider. Currently only Gemini models are supported.
      """
      if provider.lower() == "gemini":
          return {
