MCP server for parallel browser automation with Playwright

개요

A Model Context Protocol (MCP) server that enables AI agents to control in parallel. Existing browser automation MCP servers (Chrome DevTools MCP, Playwright MCP) share a single browser instance across all sessions, causing conflicts when multiple AI agents try to use them simultaneously. playwright-parallel-mcp creates by spawning independent MCP backend processes, enabling true parallel browser automation. playwright-parallel-mcp uses a that spawns child MCP server processes for each session: - : Each session runs in a separate OS process - : Works with any MCP browser automation server - : Uses @latest versions, no dependency updates needed - : Sessions are cleaned up on timeout or process exit This is architecturally guaranteed by process-level separation.

playwright-parallel-mcp

English | 日本語 | 中文

A Model Context Protocol (MCP) server that enables AI agents to control multiple independent browser instances in parallel.

The Problem

Existing browser automation MCP servers (Chrome DevTools MCP, Playwright MCP) share a single browser instance across all sessions, causing conflicts when multiple AI agents try to use them simultaneously.

The Solution

playwright-parallel-mcp creates isolated browser instances for each session by spawning independent MCP backend processes, enabling true parallel browser automation.

Architecture (v0.3.0+)

playwright-parallel-mcp uses a wrapper architecture that spawns child MCP server processes for each session:
