Choosing a Browser MCP: CDP, Playwright MCP, or Puppeteer MCP?

@playwright/mcp uses an accessibility tree instead of screenshots, cutting token cost by 10–50x — the best default for AI agents doing web automation. Puppeteer MCP fits screenshot-heavy tasks. Direct CDP via MCP is for low-level tooling or domains that Playwright/Puppeteer don't expose.

@modelcontextprotocol/server-puppeteer: The Official Puppeteer MCP Server

server-puppeteer is the Puppeteer wrapper in the official MCP servers monorepo — seven lean tools built around screenshots and evaluate. Token cost is significantly higher than @playwright/mcp per interaction, but it fits well when the screenshot itself is the deliverable or custom JS execution is the core need.
