概要

What is Parallel Browser Mcp?

Parallel Browser Mcp is an MCP server for parallel browser automation. It exposes a numeric session model so one client can create and control multiple browser sessions simultaneously across several providers: local Playwright Chromium, Browserbase, Anchor Browser, and Cloudflare Browser Run. It is designed for developers building AI-driven browser automation workflows within MCP‑compatible clients.

How to use Parallel Browser Mcp?

Install via npm (npx parallel-browser-mcp@latest) and add the server configuration to your MCP client (e.g., Claude, Cursor, VS Code). The server runs over stdio. Create sessions by calling start_session with a provider, then use any browser_* tool by passing the returned numeric sessionId. Provider credentials and defaults are set in environment variables or a JSON config object.

Key features of Parallel Browser Mcp

  • Multiple concurrent browser sessions with numeric IDs in memory
  • Unified provider abstraction for Playwright, Browserbase, Anchor, and Cloudflare
  • Session management tools: start, close, close all, list sessions
  • Over 20 browser automation tools (navigate, click, fill, screenshot, and more)
  • Configuration via environment variables, config file, or inline JSON

Use cases of Parallel Browser Mcp

  • Run multiple browser-based agents in parallel from a single MCP client
  • Automate web scraping and form filling across different browser providers
  • AI agents that need to manipulate several pages concurrently (e.g., research, data extraction)
  • Test browser automation scripts locally with Playwright and switch to cloud providers

よくある質問

1

Which providers does Parallel Browser Mcp support?

It supports four providers: Playwright (local Chromium), Browserbase (via `@browserbasehq/sdk`), Anchor (via `anchorbrowser`), and Cloudflare (via Cloudflare Browser Run).

2

How do I configure provider credentials?

Credentials are set via environment variables: `BROWSERBASE_API_KEY`, `ANCHOR_API_KEY`, `CLOUDFLARE_API_TOKEN`, and `CLOUDFLARE_ACCOUNT_ID`. Playwright requires no credentials. Additional provider‑specific options can be set in a JSON configuration provided through `BROWSER_MCP_CONFIG` or a config file.

3

How do I run the server?

You can run it locally with `node dist/index.js` after building, or use the npm CLI: `npx parallel-browser-mcp@latest`. The server communicates over stdio, so it integrates with any MCP client that supports stdio transport.

4

What tools are available for controlling a session?

The server offers session tools (`start_session`, `close_session`, `close_all_sessions`, `get_sessions`) and browser tools such as `browser_navigate`, `browser_click`, `browser_fill`, `browser_screenshot`, `browser_snapshot`, `browser_evaluate`, and more—over 20 in total.

5

How do I start and use a session?

Call `start_session` with a provider name (e.g., `"playwright"`). The response includes a numeric session ID. Then call any `browser_*` tool with `{ "sessionId": <id>, ...}`. Finally, call `close_session` to release resources.
