One native binary. No Chrome. Official MCP Registry identity: mcp-name: io.github.protostatis/unbrowser unbrowser is a stateful, non-visual web runtime for agents. It sits between curl /WebFetch and a real browser: it retains cookies and DOM state, returns queryable element refs, handles links and HTML forms, detects challenge and SPA signals, and can run bounded QuickJS page scripts when static HTML is not enough. Default navigate is a fast static/SSR pass. Set exec scripts: true only when you need bounded QuickJS execution. Heavy SPAs, pixels, V8 fidelity, extensions, and interactive anti-bot challenges belong in a real Chrome tier. Try the live public-web demo before installing. It accepts only the fixed public source sets shown on the page; do not send private data, cookies, or authenticated tasks through it. A shared Streamable HTTP MCP endpoint is available at https://unchainedsky.com/unbrowser-mcp for public smoke tests; production sessions should use a local install. Use unbrowser only on sites, accounts, and data you are permitted to access. Challenge detection and cookie import do not grant permission to bypass access controls or site terms. Treat session cookies as credentials: keep them local, scope them to the authorized task, and never send them to the public demo.
