Enable any LLM (e.g. Claude) to interactively debug any language for you via MCP and a VS Code Extension
I found llm debugging to work better if you give the llm access to a debugger.

- Project mention: Show HN: TraceRoot – Open-Source Agentic Debugging for Distributed Services | news.ycombinator.com | 2025-08-01
Yes, we can connect for example CC with MCPs. But this may not work well for example if user wants to check the latency for previous 10 days error log on function A. By using MCP the agent needs to get 10 days error logs at first and then somehow get the latency and correlates them, apply filters for function A. IMO it will hallucinate a lot if there are too many tools, logs and traces. But on TraceRoot platform we "mixed" all necessary data at first, and based on user's query apply filters on structured data, which is more accurate, straightforward and efficient. Here is the README of the general design https://github.com/traceroot-ai/traceroot/tree/main/rest/age...
