v0.1.0 — initial OSS wedge

The first public release of prufa-mcp — an Apache-2.0 MCP server that
audits your vibe-coded app for the things humans miss: tracking pixels,
broken flows, consent violations, console errors.

Install

pip install prufa-mcp

Get a free API key at https://prufa.dev — the first audit is free, no card required.

Then add to your .mcp.json (Claude Code, Cursor, Cline, Continue):

{
  "mcpServers": {
    "prufa": {
      "command": "prufa-mcp",
      "env": { "PRUFA_API_TOKEN": "your-prufa-api-key" }
    }
  }
}
