  The main handler function that executes the tool logic by calling the Helius SDK's getAsset method with the provided asset ID and formatting the response.

  export const getAssetHandler = async (input: { id: string }): Promise<ToolResultSchema> => {
    try {
      const asset = await (helius as any as Helius).rpc.getAsset(input.id);
      return createSuccessResponse(`Asset details: ${JSON.stringify(asset, null, 2)}`);
    } catch (error) {
      return createErrorResponse(`Error getting asset: ${error instanceof Error ? error.message : String(error)}`);
    }
  }
