Project mention: Show HN: We made an MCP server so Cursor can debug Node.js on its own | news.ycombinator.com | 2025-03-22
Thanks for the detailed write-up, this is super useful! I really appreciate it.
> Claude captures all the NPM commands from the package json into the instructional file
Oh neat, I didn't know that. I'll try to use `/init` next time!
> it kept trying to run `npm run dev` which spins up the app itself. That's... not ideal since I'm running it myself so it can hot-reload
+1 I regularly notice that behaviour too. I'm running node in dev mode, then Cursor wants to run node, but the port is already in use.
> I'd be curious about is if there is a "clientside browser" MCP
Great point, I noticed this is a common feature request for front-end development. I haven't used it myself, but multiple people mentioned BrowserTools [1]. I think it can read the Dev Tools console, but I'm not sure about multimodal or access to the DOM.

Project mention: Show HN: We made an MCP server so Cursor can debug Node.js on its own | news.ycombinator.com | 2025-03-22
Up to you, but there's actually a formal logging pathway[1] in MCP that has the potential to put this message somewhere that either of the two consumers[2] of your service could see it https://github.com/hyperdrive-eng/mcp-nodejs-debugger/blob/v...
1: https://spec.modelcontextprotocol.io/specification/2024-11-0...
2: the person, and while I don't have evidence of it I also can't think why the LLM couldn't see the message, either
