Prufa MCP

Vibe-coded apps ship faster than anyone can review them. In June 2026 we audited 49 fresh Show HN launches - 38 had a critical bug on day one: a broken signup, a silent console error, analytics that never fired, a consent banner that did nothing. It runs locally over stdio via the published package.

People who work with Prufa and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
