Puppeteer (browser automation)

Lets an AI assistant drive an actual browser — navigate to pages, click elements, fill forms, take screenshots — useful for testing a web flow, scraping content that needs JavaScript to render, or having the assistant show you what a page actually looks like. ```json { "mcpServers": { "puppeteer": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-puppeteer"] } } } ``` This is one of the more powerful/riskier servers to grant — a browser it controls can submit forms, click buttons, and navigate anywhere, so only enable it in a session where you're comfortable with an assistant taking real actions on pages, and supervise it on anything involving a logged-in account or a destructive action (submitting, deleting, purchasing). Check current docs for headless-vs-visible browser options and any sandboxing settings before using it against sites you care about.
