Show HN: Comet MCP – Give Claude Code a browser that can click

I tried it. My Perplexity premium expired, maybe that is it, but it barely did anything.

When I put prompt you suggested, it did open Perplexity in Comet and then I guess didn't get response even though Perplexity did research, so it used regular search mcp to get results...

It is cool idea, this is what I would like to have, something to automate boring stuff. Find all LinkedIn connections that are not active and remove them from my network for example.

I don't think it is your mcp or code, as tech is just not there yet. It is much easier to accomplish this through other automations.

People are already going full Leroy Jenkins with this stuff, and OpenAI, other labs are snarfing up their usage data. Hopefully with their brave sacrifice, they can figure out all the security pitfalls before it becomes common enough that someone with a clever jailbreak ends up pulling of a billion dollar heist, or orders pizza for half the country.

It's 100% absolutely not safe yet. You can effectively copy and paste Pliny prompts and pwn any of the frontier lab models. Anyone with a little time and creativity can tailor a unique one and set hidden text traps for AI browsers or agents, and depending on what access you've given the software it could be very dangerous.

I've used chrome devtools mcp successfully to do all kinds of advanced in browser tasks, agents like claude code can write js and inject it into the context in a live browser and do all kinds of neat tricks. I've used this extensively in gemini-cli.

There are folks on X running vibe-coded Polymarket arbitrage bots playing with hundreds of thousands of dollars. Some people have pretty wild risk tolerances!

I noticed that /plugins

Doesn't lost plugins anymore. I'm sure I installed playwright using that menu, but now it lists no plugins (and the plugin can't be found locally)

However, claude add mcp and /mcp still works.
