Hey HN,Claude Code is pretty agentic now. It writes scripts, calls APIs, uses CLIs. But when something requires actually clicking through a website, it stops and asks me to do it.Problem is, I'm often unfamiliar with these platforms myself. "Go to App Store Connect and generate a P8 key" okay but where? I end up spending 10 minutes navigating menus I've never seen before.I started delegating these tasks to Perplexity's Comet browser. It handles the clicking, returns what I need. But copy-pasting between Claude and Comet got old fast.So I built this MCP server to connect them directly. Now when Claude needs to interact with a website that has no API, it can just ask Comet to handle it. Examples: - Grab my app ID from RevenueCat dashboard - Generate a P8 key in App Store Connect - Navigate admin panels behind login walls I tried Playwright MCP but having Claude do the clicking itself overwhelms the context window. Comet's agentic browsing just works better in my experience.Comet doesn't have an API, so this uses CDP to communicate with it directly.

Could you build this?
Yes Comet MCP is a Model Context Protocol (MCP) server that wraps Playwright or Puppeteer to expose automated browser clicking and navigation actions to Claude.

Concerns raised: Security risks - AI could be tricked into accessing bank accounts or transferring money, Not safe yet - vulnerable to jailbreaks and hidden text traps, Brittleness of MCP/CLI/browser stack unless using Opus 4.5, Technology not mature enough for reliable automation, Unreliable results - doesn't always return responses from browser interactions
Feature requests: Automate LinkedIn connection pruning and management tasks, Narrower use-case with less autonomous risk (constrained web search)
