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 who work with browser automation, chromium and cloakbrowser and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install CloakBrowser MCP

Claude Code

claude mcp add swimmwatch-cloakbrowser-mcp -- npx -y cloakbrowser-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "swimmwatch-cloakbrowser-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "cloakbrowser-mcp"
      ]
    }
  }
}

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