AntiCheck

Validate code architecture, security issues, and AI vibe-coding anti-patterns directly from your IDE using the Model Context Protocol (MCP).

AntiCheck gives AI assistants like Claude, Cursor, and Windsurf the ability to act as Senior Engineers—auditing your local codebase for architectural flaws, security vulnerabilities, frontend issues, and common AI-generated bugs.

Install

# Install globally
npm install -g anticheck

# Or use directly via npx
npx anticheck

Usage

AntiCheck operates as an MCP server. It is meant to be run by an AI Assistant rather than consumed directly by humans.

Using with Cursor

Navigate to Cursor Settings > Features > MCP Servers and click + Add New MCP Server.

• Name: anticheck
• Type: command
• Command: npx
• Args: -y anticheck

Restart Cursor to see the tools.

Using with Claude Desktop

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "anticheck": {
      "command": "npx",
      "args": ["-y", "anticheck"]
    }
  }
}

Why AntiCheck?

AI coding tools are incredibly fast but often produce specific types of technical debt known as Vibe Coding. AntiCheck is specifically designed to hunt these down.

• ❌ Detects Bad Architecture: Catches god classes, missing DTOs, and dependency arrows pointing the wrong way.
• 🔒 Highlights Security Smells: Finds hardcoded secrets, authorization bypasses, and unvalidated inputs.
• ⚡ Catches Vibe Coding Bugs: Flags missing React/Vue hooks cleanup, swallowed exceptions, infinite recursion, and missing loading/error states.
• 🤖 Native MCP Integration: The AI Assistant uses AntiCheck to find the bugs, and then fixes them for you automatically.

Output Example

Once installed, ask your AI: "Run a full architecture and security audit using anticheck."

The AI will scan your code and output a structured diagnostic:

❌ Anti-pattern detected:

Rule Title: Missing Pagination (v1.0) Severity: High (Weight: 80) Finding: The endpoint GET /users executes .ToList() on the DbSet without Skip or Take. Impact: Will cause memory exhaustion and DB timeouts in production. Fix: I will implement offset pagination for you.
