Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {

      ],
      "env": {
        "BROWSERSOLVER_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http browsersolver https://mcp.browsersolver.com/ --header 'x-api-key: your-value'

Or run it on your computer

claude mcp add browsersolver --env BROWSERSOLVER_API_KEY=your-value -- npx -y @browsersolver/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Common questions

Is BrowserSolver safe?

It passed 3 of 3 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?

You need to fill in: BROWSERSOLVER_API_KEY, x-api-key

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

BrowserSolver MCP Server

Official Model Context Protocol server for the BrowserSolver web unlocker API.

Unlock, render, crawl and screenshot any website — anti-bot bypass and technology detection through one API.

It lets Claude, Cursor, VS Code, Windsurf and any MCP client call the API as tools. Runs over stdio (local) or Streamable HTTP (self-hosted).

Requirements

Node.js 20 or newer
a BrowserSolver API key — sign up, then copy it from the dashboard

Hosted server (recommended)

BrowserSolver runs this server for you at `https://mcp.browsersolver.com/` (Streamable HTTP). Send your API key in the x-api-key header; nothing to install.

claude mcp add --transport http browsersolver https://mcp.browsersolver.com/ --header "x-api-key: YOUR_API_KEY"

"mcpServers": { "browsersolver": { "url": "https://mcp.browsersolver.com/", "headers": { "x-api-key": "YOUR_API_KEY" } } } }

The hosted server and this package expose the same API; run the package locally when you want stdio, your own network egress, or to self-host it.

Run it locally

Claude Code

claude mcp add browsersolver --env BROWSERSOLVER_API_KEY=YOUR_API_KEY -- npx -y @browsersolver/mcp

Claude Desktop, Cursor, Windsurf and other clients

Add the server to the client's MCP configuration (claude_desktop_config.json, .cursor/mcp.json…):

"mcpServers": { "browsersolver": { "command": "npx", "args": ["-y", "@browsersolver/mcp"], "env": { "BROWSERSOLVER_API_KEY": "YOUR_API_KEY" } } } }

VS Code

"servers": { "browsersolver": { "type": "stdio", "command": "npx", "args": ["-y", "@browsersolver/mcp"], "env": { "BROWSERSOLVER_API_KEY": "${input:browsersolver-api-key}" } } }, "inputs": [ { "type": "promptString", "id": "browsersolver-api-key", "description": "BrowserSolver API key", "password": true } ] }

Claude Desktop extension

Download the .mcpb bundle from the releases page and open it; Claude Desktop asks for your API key.

Docker

docker build -t browsersolver-mcp .

docker run -i --rm -e BROWSERSOLVER_API_KEY=YOUR_API_KEY browsersolver-mcp

Tools

Tool	Description
`stats`	Infrastructure health for an engine or endpoint over the last hour. Not scoped to your account or tenant. Enabled per account: HTTP 403 means contact support to activate it.
`usage`	Retrieve real-time usage statistics and credit balance for your BrowserSolver account.
`website_antibot`	Single-pass scan that names the bot-protection vendor in front of a URL so you can choose the right BrowserSolver fetch tier next.
`website_crawler`	Fast HTTP pull of public HTML with no browser session. Ideal when the first response already contains the content you need.
`website_rendering`	Run a managed browser session against a public URL and collect the HTML after client-side scripts finish. Prefer Crawler for static markup; escalate to WebUnlocker on approved hosts when challenges p…
`website_screenshot`	Turn any public URL into a PNG, JPEG, WebP, or PDF asset rendered by BrowserSolver. No local Chromium fleet to operate.
`website_technology`	Map CMS, frameworks, analytics, CDN, and security tooling exposed by a public URL. Choose simple lists or expert metadata with confidence scores.
`website_webunlocker`	BrowserSolver's highest HTML fetch tier for retail and marketplace hosts on your account whitelist. Solves persistent bot challenges that still block Rendering.

Every tool that calls the API consumes credits. JSON results are returned as text; images are returned inline and other files (PDF…) as embedded resources, up to 4 MB.

Streamable HTTP

npx @browsersolver/mcp --http --port 3000

The endpoint is POST /mcp (stateless, JSON responses). Each client sends its own key in the x-api-key header (or Authorization: Bearer ); the server never uses a key of its own. It binds to 127.0.0.1 by default and rejects browser origins unless you allow them — put it behind TLS before exposing it.

createHttpHandler() is exported for Fetch-compatible runtimes (Cloudflare Workers, Deno, Bun):

import { createHttpHandler } from "@browsersolver/mcp";

export default { fetch: createHttpHandler({ allowedOrigins: [] }) };

Security

The API key is read from BROWSERSOLVER_API_KEY (stdio) or the request headers (HTTP) and removed from error messages.
Content fetched from websites is untrusted: the server instructions tell the model to treat it as data, not instructions.
See SECURITY.md to report a vulnerability.

Development

npm install

npm test npm run build npx @modelcontextprotocol/inspector node dist/stdio.js

Built on the SDK

The server uses the official Node.js SDK (@browsersolver/sdk).
