Common questions

Is Capmonster MCP Patchright Captcha Solver 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 (1.1.3) reached the registry 2 months 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.

capmonster-mcp-patchright: Stealth Browser MCP Server for AI Agents

Building an AI agent that has to work on anti-bot protected sites? Pair this stealth browser with the CapMonster Cloud MCP server, a cost-effective capsolver alternative and 2captcha alternative: reCAPTCHA v3 starts at $0.90 per 1,000 solves, which is up to 38% cheaper than 2Captcha and 10% cheaper than Capsolver. See the pairing example and the comparison below.

Stealth browser MCP server for AI agents — 66 tools, Patchright-powered, reduced CDP automation signals.

Built for automation on sites protected by Cloudflare, Akamai, Kasada and DataDome. When the page shows a CAPTCHA, pair it with the CapMonster Cloud MCP server: this server drives the browser, CapMonster Cloud solves the CAPTCHA. Use the 66 browser_* tools for AI-agent web scraping and browser automation with Claude, GPT and other MCP clients, powered by Patchright, a patched Playwright with reduced automation signals.

Fork of mcp-patchright that adds a per-call world: "main" option to browser_evaluate / browser_run_code_unsafe, so page-defined window globals are visible and callable. Defaults to Patchright's isolated stealth world (matching upstream); opt into main only when a page's own script needs to see or be called by your evaluated code. Everything else matches upstream mcp-patchright.

Why Patchright, not Playwright?

	Playwright	Patchright
`Runtime.enable`	✅ sends (detectable)	❌ removed
`Console.enable`	✅ sends	❌ removed
`--enable-automation` flag	✅ present	❌ removed
`navigator.webdriver`	`true`	`false` / `undefined`

Quick start

npm i -g capmonster-mcp-patchright

capmonster-mcp-patchright --port 9321 --host 127.0.0.1

With Claude / GPT / agents

"mcpServers": { "patchright": { "command": "npx", "args": ["capmonster-mcp-patchright", "--port", "9321", "--host", "127.0.0.1"] } } }

🔗 Pair with CapMonster Cloud MCP for captcha solving

This server drives the browser; the CapMonster Cloud MCP server solves the CAPTCHA and the agent injects the token back into the page. Add both servers to your MCP client config:

"mcpServers": { "patchright": { "command": "npx", "args": ["capmonster-mcp-patchright", "--port", "9321", "--host", "127.0.0.1"] }, "capmonster": { "command": "uvx", "args": ["capmonster-mcp"], "env": { "CM_API_KEY": "your_api_key_here" } } } }

Features

66 MCP tools — full browser automation surface
`world: "main"` opt-in — browser_evaluate / browser_run_code_unsafe can run in the page's real world to see/call page-defined globals (default stays isolated/stealth)
`browser_find` — search the current aria snapshot for text/regex, cheaper than a full browser_snapshot
`browser_save_blob` — save a Blob/data URL produced by page code to disk
3 transports — stdio, SSE, Streamable HTTP (/mcp)
Persistent profiles — real Chrome profile, reuse across sessions
Multi-page — tab management (new, list, switch, close)
Owner-scoped HTTP sessions — isolate tabs per caller with owner query/header
CDP attach — control an already-running Chrome
Network tracking + interception — request list/detail, offline toggle, block/mock routes
Session import/export — browser_storage_save / browser_storage_load (cookies + localStorage)
Granular storage — per-key cookie / localStorage / sessionStorage CRUD (browser_cookie_*, browser_localstorage_*, browser_sessionstorage_*)
Authenticated API requests — browser_api_request reuses session cookies (hybrid scraping)
Text/HTML extraction — browser_get_visible_text / _html (token-light)
Iframe-aware — pass frameSelector to any element tool (click/fill/type/hover/press/wait_for/select/drag) to act inside an iframe
PDF export — browser_save_pdf via CDP (works in headed/stealth mode)
Video recording — browser_start with recordVideo, browser_video_save; .webm flushed on browser_close
Element highlight — browser_highlight / browser_hide_highlight overlays for screenshots & recordings
Stealth profiles — proxy / geolocation / locale / timezone / colorScheme
Console capture — real-time console message stream
Fingerprint check — browser_fingerprint_check diagnostics
Virtual passkeys — create, import, list, and delete WebAuthn credentials with private keys redacted by default

Development

Owner-scoped HTTP sessions

HTTP mode requires a stable owner on the MCP URL (?owner= ) or with the X-Browser-Owner header. Page listing, switching, navigation, and closing are restricted to that owner's tabs. Delete /owners?owner= to close all tabs owned by one caller without stopping the browser or clearing the profile.

npm install

npm run build node dist/index.js

Release

Install the matching Chromium build once, then prepare a release from the exact dependency versions in package-lock.json, run the full verification suite, and inspect the package without publishing it:

npx patchright install chromium

npm run release:check npm publish

By default, browser_start launches Chromium via patchright as headed real Chrome with a persistent profile at:

~/.maestro/stealth-playwright-mcp/profiles/default

You can override it with the userDataDir tool argument or STEALTH_PLAYWRIGHT_USER_DATA_DIR.

To attach to an already-running Chrome instead of launching one, start Chrome with remote debugging and pass cdpEndpoint to browser_start:

google-chrome --remote-debugging-port=9222 --user-data-dir=$HOME/.maestro/stealth-playwright-mcp/profiles/cdp

{ "cdpEndpoint": "http://127.0.0.1:9222" }

browser_snapshot returns Playwright's AI aria snapshot. Use [ref=eN] values from that snapshot with browser_click, browser_fill, browser_type, browser_hover, browser_press, and browser_wait_for by passing { "ref": "eN" }. CSS selectors remain supported via { "selector": "..." }.

MCP config example:

"mcpServers": { "patchright": { "command": "node", "args": ["/path/to/capmonster-mcp-patchright/dist/index.js"] } } }
