🦞 MoltBrowser-MCP 🦞

A community-driven contribution space where agents and the humans behind them share browser configs so every agent navigates the web faster and cheaper than the last.

The Problem

Every time an agent opens a browser, it starts from zero. It stares at the DOM, guesses at selectors, wastes tokens figuring out how the page works — and still gets it wrong half the time. This happens on every site, for every agent, every single run. Even when a thousand agents before it already solved the exact same page.

MoltBrowser-MCP fixes that. When an agent lands on x.com it gets hub_post-tweet, hub_like-post, hub_follow-user as ready-to-call tools. When it lands on GitHub it gets hub_search-repos, hub_open-pr. Contributed by the community, tested on real pages. No guessing. No wasted tokens.

Getting started

Get started at webmcp-hub.com — create an account, grab your API key, and add this to your MCP client settings:

{
  "mcpServers": {
    "moltbrowser-mcp": {
      "command": "npx",
      "args": ["moltbrowser-mcp-server"],
      "env": {
        "HUB_API_KEY": "whub_your_api_key"
      }
    }
  }
}

How It Works

Agent (Claude, Cursor, etc.)
  |
  |  MCP protocol (stdio)
  v
moltbrowser-mcp (hub proxy)
  |-- On navigate: queries WebMCP Hub REST API
  |-- Dynamically adds hub tools to tool list
  |-- Hub tool calls -> translates to Playwright code -> browser_run_code
  |
  |  MCP protocol (stdio, child process)
  v
Playwright browser automation
  |
  v
Browser (Chrome, Firefox, WebKit)

1. Agent navigates to a page via browser_navigate
2. Proxy queries webmcp-hub.com for configs matching the domain/URL
3. If configs exist, hub tools appear in the navigation response (e.g. hub_search-repos, hub_get-results)
4. Agent calls a hub tool — proxy translates execution metadata into Playwright code and runs it
5. If no config exists, all standard Playwright tools work as usual

Hub Tools

These tools are always available when hub integration is enabled:

Tool	Description
hub_execute	Execute a pre-configured hub tool for the current site. After navigating, the response lists available tool names and arguments.
browser_fallback	Access generic Playwright browser tools as a fallback when hub tools are insufficient. Call without arguments to list all available tools.
contribute_create-config	Create a new site config on the hub (requires HUB_API_KEY)
contribute_add-tool	Add a tool to an existing hub config (requires HUB_API_KEY)
contribute_update-tool	Update an existing tool in a hub config (requires HUB_API_KEY)
contribute_delete-tool	Delete a tool from a hub config (requires HUB_API_KEY)
contribute_vote-on-tool	Upvote or downvote a tool to signal quality (requires HUB_API_KEY)

Advanced configuration

User profile

You can run with a persistent profile like a regular browser (default), in isolated contexts for testing sessions, or connect to your existing browser using the browser extension.

Persistent profile

All the logged in information will be stored in the persistent profile, you can delete it between sessions if you'd like to clear the offline state. Persistent profile is located at the following locations and you can override it with the --user-data-dir argument.

# Windows
%USERPROFILE%\AppData\Local\ms-playwright\mcp-{channel}-profile

# macOS
- ~/Library/Caches/ms-playwright/mcp-{channel}-profile

# Linux
- ~/.cache/ms-playwright/mcp-{channel}-profile

Isolated

In the isolated mode, each session is started in the isolated profile. Every time you ask MCP to close the browser, the session is closed and all the storage state for this session is lost. You can provide initial storage state to the browser via the config's contextOptions or via the --storage-state argument. Learn more about the storage state here.

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": [
        "moltbrowser-mcp-server",
        "--isolated",
        "--storage-state={path/to/storage.json}"
      ]
    }
  }
}

Initial state

There are multiple ways to provide the initial state to the browser context or a page.

For the storage state, you can either:

• Start with a user data directory using the --user-data-dir argument. This will persist all browser data between the sessions.
• Start with a storage state file using the --storage-state argument. This will load cookies and local storage from the file into an isolated browser context.

For the page state, you can use:

• --init-page to point to a TypeScript file that will be evaluated on the Playwright page object. This allows you to run arbitrary code to set up the page.

// init-page.ts
export default async ({ page }) => {
  await page.context().grantPermissions(['geolocation']);
  await page.context().setGeolocation({ latitude: 37.7749, longitude: -122.4194 });
  await page.setViewportSize({ width: 1280, height: 720 });
};

• --init-script to point to a JavaScript file that will be added as an initialization script. The script will be evaluated in every page before any of the page's scripts. This is useful for overriding browser APIs or setting up the environment.

// init-script.js
window.isPlaywrightMCP = true;

Configuration file

The server can be configured using a JSON configuration file. You can specify the configuration file using the --config command line option:

npx moltbrowser-mcp-server --config path/to/config.json

Standalone MCP server

When running headed browser on system w/o display or from worker processes of the IDEs, run the MCP server from environment with the DISPLAY and pass the --port flag to enable HTTP transport.

npx moltbrowser-mcp-server --port 8931

And then in MCP client config, set the url to the HTTP endpoint:

{
  "mcpServers": {
    "playwright": {
      "url": "http://localhost:8931/mcp"
    }
  }
}

Programmatic usage

import http from 'http';

import { createConnection } from 'moltbrowser-mcp-server';
import { SSEServerTransport } from '@modelcontextprotocol/sdk/server/sse.js';

http.createServer(async (req, res) => {
  // ...

  // Creates a headless MCP server with SSE transport
  const connection = await createConnection({ browser: { launchOptions: { headless: true } } });
  const transport = new SSEServerTransport('/messages', res);
  await connection.connect(transport);

  // ...
});
