Parallel Browser MCP

parallel-browser-mcp is an MCP server for parallel browser automation. It exposes a numeric session model over MCP so one client can create and control multiple browser sessions at the same time across multiple browser providers. It runs locally over stdio via the published package.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Parallel Browser MCP

before you install - you'll need

Set PLAYWRIGHT_USE_CLOAKBROWSER before connecting. BROWSER_MCP_CONFIG is optional or environment-specific per the README.

Claude Code

claude mcp add etairl-parallel-browser-mcp -- npx -y parallel-browser-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "etairl-parallel-browser-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "parallel-browser-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

03 · What Parallel Browser MCP can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)

- start_session is intentionally small. Provider-specific behavior belongs in MCP configuration, not tool inputs. - The server logs to stderr so stdout stays clean for MCP JSON-RPC traffic. - Browserbase and Anchor Browser are normalized to Playwright page operations after connection, so the browser tools stay provider-agnostic.
