Output display truncation

[yuki-js]

If MCP server gives extremely long output, the rendering (especially scrolling) consumes time, framerate drops significantly, and eventually the VS Code window freezes.

If the response string could be truncated, it would not happen.

To address the issue of long output causing performance problems in Visual Studio Code, you can utilize the built-in feature of the MCP to truncate or limit the size of the output. Specifically, when dealing with large text files, the MCP automatically truncates the content if it exceeds a certain line limit (e.g., 500 lines), displaying only the initial lines along with a truncation notice. This can help prevent the VS Code window from freezing due to excessive output ^[1].

Additionally, the search_files tool in the Roo Code documentation is designed to truncate lines longer than 500 characters and limit results to a maximum of 300 matches before rendering, which can also help manage large outputs ^[2]. Adjusting these settings or using these tools can improve performance and prevent the issues you're experiencing.

Thanks for the report; our command execution component uses https://virtuoso.dev/ to solve this problem and I think we can do the same for our MCP integration.
