Visual UI Debug Agent MCP
By Sami Halawa. Category: MCP servers for testing. Homepage
The project's README describes Visual UI Debug Agent MCP (VUDA) as an MCP server that uses Playwright to inspect and test web interfaces. It exposes Playwright-based tools, including screenshots, visual comparison of two rendered states, UI workflow validation and HTTP endpoint testing, to any MCP-compatible client. The MCP client calls the tools on demand. The server runs locally over stdio through npx or a Docker image, and the browser can optionally run on Browserbase, Anchor Browser or another CDP endpoint. It is maintained by Sami Halawa under the ISC licence.
