Common questions
Is Bezlo MCP safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 11 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

Bezlo — open agent layer
Bezlo puts any web page inside a true-to-size iPhone / iPad / Android frame and lets an AI agent see it and act on it: screenshots, interactive-element lists, layout diagnostics (overflow, safe-area, touch identity), console/page errors, network mocks, tap/type/scroll flows, device matrix runs — and report.json / JUnit / mp4 evidence.
This repository is the MIT-licensed agent layer:
mcp/— MCP stdio server + CLI + session/capture engine (also on npm asbezlo-mcp)action.yml+examples/— composite GitHub Action (PR screenshots + JUnit + video)skill/— thebezlo-previewskill for Claude Code / skills-compatible agentsserver.json— official MCP registry manifestdocs/MCP.md— full tool reference
The Chrome extension itself is proprietary and lives in a separate private repo (extension/, store art, brand). This repository contains no extension code, store assets or brand artwork. The name Bezlo and its logo are not licensed for reuse.
Install
# MCP (Claude Code / Claude Desktop / Cursor)npm install -g bezlo-mcp claude mcp add bezlo -- npx -y bezlo-mcp
or run from a checkout
node mcp/cli.mjs --list
The package bundles no browser: install Chrome/Chromium (or set RP_CHROME). Chrome for Testing is recommended; WebKit mode additionally needs npx playwright install webkit.
Quick CLI

Artifacts: final screenshot, report.json, junit.xml, optional mp4/gif. Outputs: pass, report, junit, video, gif, screenshot, artifacts.
Engines
- chromium (default) — Chrome's own emulation engine (same as the extension's frames): real touch, mobile UA and client hints, DPR; full recording and CDP accessibility.
- webkit — Playwright WebKit, a Safari-flavoured approximation (not real iOS Safari; no recording / CDP a11y).
