invisible_playwright_mcp

invisible_playwright_mcp is an agent framework - Your AI agent browses the web without captchas: self-hosted Python MCP server on undetected anti-detect stealth Firefox, for browser automation, scraping, computer use.

Overview

Other AI browser agents get captchas. This one is invisible to anti-bots.

We bring the interface, you bring an OpenRouter key. Chat on the left, the live browser on the right.

Anything that needs real web automation: a browser rather than an API, and a person's judgement about what is on the page.

It drives the page the way a person would: the pointer moves, keys are pressed.

• '--openrouter-key' Your key, or the 'OPENROUTER_API_KEY' variable. - '--model' An OpenRouter model id, or 'INVISIBLE_MCP_MODEL'. Defaults to 'z-ai/glm-5.3-flash'. - '--proxy' Optional. 'http://user:pass@proxy.example.com:8080' or 'socks5://proxy.example.com:1080'. Host and port are both required. The timezone, locale and egress follow it. - '--binary' An engine binary you already have. It must be the build the seal pins, or startup refuses: this skips the download, not the version check. - '--seed' An integer. Same seed, same browser identity, every run. - '--profile-dir' A directory to keep the profile in, so logins and cookies survive restarts. - '--headed' Show the browser window. The interface shows you the page anyway. - '--host', '--port' '127.0.0.1' and '8765'. Changing the host exposes an interface that has no authentication.

Rather than retyping the key and the binary path, put them in a '.env' in the directory you run from:

invisible_playwright_mcp is open-source, written primarily in Python, with 31,643 GitHub stars under the MIT license. The latest release is v0.70.0 (2026-09-23).

Key capabilities

From the project's documentation:

• --openrouter-key Your key, or the OPENROUTER_API_KEY variable.
• --model An OpenRouter model id, or INVISIBLE_MCP_MODEL. Defaults to z-ai/glm-5.3-flash.
• --proxy Optional. http://user:pass@proxy.example.com:8080 or
• --binary An engine binary you already have. It must be the build the seal
• --seed An integer. Same seed, same browser identity, every run.

How it fits a local-AI stack

invisible_playwright_mcp runs on your own hardware, so pair it with a model and a GPU sized to your needs. Use the VRAM calculator to pick a model that fits your card, and see what you can run for hardware guidance. Related agent frameworks in the directory:
