slop-detect-mcp

MCP server that lets AI coding agents scan landing pages for AI-design-slop and pull a ready-to-paste fix prompt — straight from the chat.

Part of slop-detect: the 16-rule fingerprint that catches Cursor / v0 / Lovable template slop in the wild. This package wraps the live slop-detect.com API as a Model Context Protocol server, so Claude Code, Cursor, and Windsurf can audit and de-slop pages without a browser or API key.

Tools

| Tool | Input | What it does | | --- | --- | --- | | scan_page | { url } | Scans the page and returns a grade, a 0-100 score (lower is better), the slop tier, a verdict, the triggered patterns, and a shareable result URL. | | fix_prompt | { url } | Returns a copy-paste prompt that tells a coding agent exactly how to de-slop the page. |

Score polarity: 0 = no slop. Tiers are Clean (0–9), Mild (10–27), Heavy (28+).

Install

No global install needed — clients run it on demand via npx:

npx -y slop-detect-mcp

Or install it explicitly:

npm install -g slop-detect-mcp

Configure your client

All MCP clients use the same config shape. Add the server, restart the client, and ask it to "scan https://example.com for slop".

Claude Code

Add to .mcp.json in your project root (or claude_desktop_config.json for Claude Desktop):

{
  "mcpServers": {
    "slop-detect": {
      "command": "npx",
      "args": ["-y", "slop-detect-mcp"]
    }
  }
}

Or one-liner from the Claude Code CLI:

claude mcp add slop-detect -- npx -y slop-detect-mcp

Cursor

Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "slop-detect": {
      "command": "npx",
      "args": ["-y", "slop-detect-mcp"]
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "slop-detect": {
      "command": "npx",
      "args": ["-y", "slop-detect-mcp"]
    }
  }
}

Configuration

| Env var | Default | Purpose | | --- | --- | --- | | SLOP_DETECT_API | https://slop-detect.com | API base URL. Point it at a local dev build (e.g. http://localhost:8788) when hacking on the web app. |

{
  "mcpServers": {
    "slop-detect": {
      "command": "npx",
      "args": ["-y", "slop-detect-mcp"],
      "env": { "SLOP_DETECT_API": "http://localhost:8788" }
    }
  }
}

Notes

• No captcha, but rate-limited. Non-browser callers skip the Turnstile challenge, so this server works headless — but the API rate-limits per IP. If you see a rate-limit message, wait a bit before scanning again.
• Errors come back as tool content, never as crashes — a flaky page or a 429/502 returns a clear message the agent can act on.
