Local Playwright browser through residential proxies — agent picks country + sticky identity

VerifiedSTDIODesktop onlyWeb Search & ScrapingBrowser Automation

Overview

AI-generated overview

Runs a local Playwright Chromium through residential proxies, letting an assistant pick exit country, tier and a sticky per-task session at call time.

What you can do
  • Launch a local Chromium session through a residential exit in a chosen country (plus city/state on Elite), with a tier and sticky session, returning a session id
  • Navigate to URLs and read pages as markdown, text or HTML, with status, final URL and title
  • Inspect the accessibility snapshot and click or type by ref, selector or text
  • Verify the exit IP and geo through the session's proxy, rotate to a fresh identity, list available countries, and close sessions
When to use it
Useful when an assistant needs to browse sites as seen from a specific country or city, for example checking regional pricing, search results, catalogs or availability, and keep one consistent identity per task. Also a fit when you already have a residential HTTP proxy and want per-task geo control rather than a proxy fixed at startup.
Requirements
Runs locally over stdio via npx (Node.js); Chromium is downloaded on first install (~170 MB) unless installed manually. Needs proxy credentials: AETHYN_USERNAME and AETHYN_PASSWORD for the default Aethyn provider, or PROXY_HOST, PROXY_PORT, PROXY_USERNAME, PROXY_PASSWORD and an optional PROXY_USERNAME_TEMPLATE for your own HTTP proxy. AETHYN_DEFAULT_TIER must match your plan (premium or elite). HTTP proxies only; network access required.
Before you install
Requires a paid-style residential proxy account with credentials stored in your MCP config; the free trial is mentioned but pricing is not described. The assistant can click and type on live sites, so it can submit forms or trigger actions on your behalf. Traffic goes through a third-party proxy provider, and check_exit_ip contacts an external IP-info endpoint by default. Only intended for public data: no login-wall automation or CAPTCHA solving, and site terms, robots.txt and rate limits…

Installation

In SourceWeft

  1. Open Aethyn Browser Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

Aethyn Browser MCP — residential-proxy browser control for AI agents (pick the country, one identity per task)

[License: MIT] [MCP] [Playwright]

An MCP server that lets an AI agent drive a real browser through residential proxies, choosing the exit country / city, tier, and a sticky per-task session — at call time. The browser (Playwright Chromium) runs locally on your machine; you bring your own proxy credentials. Defaults to Aethyn residential proxies, and works with any HTTP proxy you configure.

The only browser MCP where the agent picks the country and holds one identity per task.

Why this exists

  • Playwright MCP drives a browser well, but its proxy is set once at server startup — one static exit for the whole session. The agent can't ask for a Japanese exit for one task and a German exit for the next.
  • Hosted "web scraping" MCPs hide the proxy and hand back JSON — no runtime control over geo or session identity, and it's their pool at their price.

This server gives the agent runtime, per-task, steerable geo + sticky identity as tools — exactly what browser agents need to pull country-specific data (pricing, SERPs, catalogs, availability) and feed it into a chart or pipeline.

Quickstart

Add the server to your MCP client — Claude Desktop (claude_desktop_config.json) or Cursor (~/.cursor/mcp.json):

json
{  "mcpServers": {    "aethyn-browser": {      "command": "npx",      "args": ["-y", "aethyn-browser-mcp"],      "env": {        "AETHYN_USERNAME": "aethyn-XXXXX",        "AETHYN_PASSWORD": "your-proxy-password",        "AETHYN_DEFAULT_TIER": "premium"      }    }  }}

Chromium is downloaded automatically on first install (~170 MB, one-time). If your environment blocks post-install scripts, run it yourself: npx playwright install chromium.

⚠️ Set the tier to match your plan. AETHYN_DEFAULT_TIER defaults to premium (port 2099). If your account is Elite, set it to elite (port 5499) — otherwise traffic hits the Premium port and the proxy returns 407 (auth rejected), even though the browser launched fine. The agent can also override per task with tier: "elite".

That's it. Ask your agent something like "Launch a browser in Japan, open example.co.jp, verify the exit IP is Japanese, and give me the page as markdown."

Tools

ToolWhat it does
aethyn_launch_browserLaunch local Chromium through a residential exit in a chosen country (+ city/state on Elite), tier, and sticky session. Returns a session_id.
aethyn_navigateGo to a URL; waits for load and returns the HTTP status, final URL, and title.
aethyn_get_contentReturn the page cleaned for reading (markdown / text / html).
aethyn_snapshotAccessibility snapshot (roles, names, [ref=..] handles) — how the agent decides what to click.
aethyn_clickClick by ref (from the snapshot) or a CSS/role/text selector.
aethyn_typeType into an input (optionally submit with Enter).
aethyn_check_exit_ipFetch IP info through the session's proxy to verify the geo actually landed.
aethyn_new_identityRotate to a fresh exit IP (same country) and clear cookies.
aethyn_closeClose the session's context and free memory.
aethyn_list_countriesDiscover available countries (and Elite cities) at runtime.

No trash-talk — just the capability delta. (Playwright MCP is great; it just wasn't built for per-task geo.)

Bring your own proxy

Aethyn is the default, but any HTTP proxy works — point PROXY_HOST at it and describe its username format with a template. [ ... ] segments are dropped when empty, and {country} {city} {state} {session} {lifetime} are filled from the agent's call:

json
{  "mcpServers": {    "browser": {      "command": "npx",      "args": ["-y", "aethyn-browser-mcp"],      "env": {        "PROXY_HOST": "gate.your-provider.com",        "PROXY_PORT": "7000",        "PROXY_USERNAME": "your-user",        "PROXY_PASSWORD": "your-pass",        "PROXY_USERNAME_TEMPLATE": "{username}-country-{country}[-city-{city}]-session-{session}-lifetime-{lifetime}"      }    }  }}

For a plain fixed proxy with no geo in the username, use "PROXY_USERNAME_TEMPLATE": "{username}".

Configuration

PROXY_HOST / PROXY_PORT / PROXY_USERNAME / PROXY_PASSWORD / PROXY_USERNAME_TEMPLATE—Bring-your-own proxy (overrides the Aethyn default).

HTTP proxies only — Chromium can't authenticate SOCKS5, so this server is HTTP-only by design.

Guardrails

This tool is for collecting public data. Please:

  • Respect robots.txt, rate limits, and each site's terms and the law. Can reach ≠ should.
  • No login/credential-wall automation, and no CAPTCHA solving — there's no such capability. If a site shows a challenge, read the page and stop rather than trying to bypass it.
  • Pace yourself. A residential IP firing dozens of requests per second is still obviously a bot.
  • Your credentials stay in your MCP config on your machine; the proxy password is never logged.
