        }
      });
      
      return {
        content: [{
          type: "text",
          text: JSON.stringify(response.data, null, 2)
        }]
      };
    } catch (error) {
      if (axios.isAxiosError(error)) {
        return {
          content: [{
            type: "text",
            text: `LTA API error: ${error.response?.data?.Message ?? error.message}`
