CloakBrowser MCP

cloakbrowser-mcp is a drop-in Playwright MCP-compatible browser automation server with unchanged upstream tools, CloakBrowser Chromium, and production-ready npm, Docker, and Streamable HTTP packaging. It runs upstream @playwright/mcp as the canonical tool surface and points that runtime at CloakBrowser. 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.
