A Chrome MCP server that talks straight to CDP. It finished the same 30-test benchmark page in 84 and 86 tool calls where Playwright MCP needed 137 and 151 — two runs each, 2026-09-03, driver Claude Opus 5, same pass rate ([Benchmarks](#benchmarks), including where it loses). Direct CDP, a11y-tree refs, multi-tab ready — 2,322 TypeScript tests, 237 Python tests.

Built for [Claude Code](https://claude.ai/claude-code), [Cursor](https://cursor.sh), and any MCP-compatible client.

**Looking for an alternative to Playwright MCP, Browser MCP, or claude-in-chrome?** Public Browser talks to Chrome directly via the DevTools Protocol — no Playwright dependency, no Chrome extension bridge, no single-tab limit. One command to install, zero config. [See benchmark comparison below](#benchmarks).

Why Public Browser?

Every Chrome MCP server has the same problem: **bulky responses, too few reliable refs.** Screenshots return 10-30x more context payload than text trees. Selector-based refs break the second the DOM rerenders. Extension bridges (Browser MCP) get stuck on the connected tab. Playwright wrappers spin up a new browser instance for every session.

Public Browser fixes this. It talks directly to Chrome via CDP (same protocol Playwright and Puppeteer use internally), returns an accessibility-tr
