Debugging

  1. chrome-devtools-mcp

    Chrome DevTools for coding agents

    Project mention: CLI over MCP: a small Chrome DevTools experiment in Copilot CLI | dev.to | 2026-06-10

    I ran the same browser smoke task through two paths: direct Chrome DevTools MCP and a custom CLI skill around mcp2cli. In GitHub Copilot CLI with gpt-5.3-codex-medium, direct Chrome DevTools MCP added about 5k tokens of upfront context before the agent did any work. The runtime table is too small and too noisy to rank the tools. The useful question is where the agent pays to discover the browser-control surface.

  15. traceroot

    TraceRoot - open-source observability and self-healing layer for AI agents. YC S25

    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...
