Best Security Scanner for Cursor IDE in 2026

Why Cursor Needs Security Scanning

Cursor is brilliant at generating code from natural language. You describe a feature, and Cursor builds it. But AI-generated code can contain the same vulnerabilities as human-written code — and sometimes more, because the AI optimizes for functionality over security.

Common issues in Cursor-generated code include:

• •Hardcoded API keys — AI often uses example keys or your actual keys from context
• •SQL injection — string interpolation in database queries instead of parameterized queries
• •Missing auth — API routes generated without authentication middleware
• •XSS vulnerabilities — dangerouslySetInnerHTML in React components
• •Prompt injection — unsanitized user input in LLM prompts

Comparing Security Scanners for Cursor

Here is how the leading security tools compare for Cursor IDE integration:

Setting Up ShipSafe with Cursor

ShipSafe integrates with Cursor via MCP (Model Context Protocol). This gives Cursor’s AI direct access to security scanning tools.

1. Install ShipSafe

npm install -g @shipsafe/cli

2. Add to Cursor MCP Config

Add ShipSafe to your Cursor MCP configuration (typically .cursor/mcp.json in your project):

{
  "mcpServers": {
    "shipsafe": {
      "command": "shipsafe",
      "args": ["mcp-server"]
    }
  }
}

3. Install Git Hooks

shipsafe hooks install

4. Add to .cursorrules

Tell Cursor’s AI to use ShipSafe automatically:

# .cursorrules
Before committing any code, run shipsafe_scan to check
for security vulnerabilities. Fix any CRITICAL or HIGH
findings before committing.

The MCP Advantage

The key advantage of ShipSafe over other scanners is MCP integration. Traditional scanners like Semgrep and Snyk run after you finish coding. ShipSafe runs while your AI writes code.

With the MCP server active, Cursor can:

• ✓Scan individual files after modifying them
• ✓Check npm packages before installing them
• ✓Verify the development environment is threat-free
• ✓Get detailed explanations of any detected vulnerability
• ✓Auto-fix common issues like moving secrets to .env files (Pro)

Works with Other AI IDEs Too

While this guide focuses on Cursor, ShipSafe’s MCP server works with any MCP-compatible tool. That includes Claude Code, Windsurf, and any future IDE that implements the Model Context Protocol. The getting started guide covers setup for all platforms.
