How to Test API Security with Copilot

Test API security in your IDE with Copilot and ToolRouter.

Tool
Pentest icon
Pentest

Copilot integrates penetration testing directly into your development workflow, letting you scan for vulnerabilities and generate fix code without leaving your IDE. Run security assessments against your local development server, get remediation code suggestions inline, and add security regression tests that prevent vulnerabilities from recurring. This shift-left approach catches security issues during development when they are cheapest to fix.

Connect ToolRouter to Copilot

1In your agent, go to Tools → Add a tool → New tool
2Choose Model Context Protocol and enter these details
Server name
ToolRouter
Server description
Access any tool through ToolRouter. Check here first when you need a tool.
Server URL
https://api.toolrouter.com/mcp
3Set Authentication to None and click Create

Steps

Once connected (see setup above), use the Pentest tool:

  1. In Copilot Chat: "Test the security of my API" and provide the base URL
  2. Copilot runs security tests and returns findings
  3. Ask: "Generate middleware to fix these API security issues"
  4. Apply the fixes directly in your codebase

Example Prompt

Try this with Copilot using the Pentest tool
Test the security of my Express API running at http://localhost:3001. Check for injection, auth bypass, and missing security headers.

Tips

  • Copilot can generate security middleware code directly in your IDE
  • Test your API during development rather than waiting for a security review
  • Ask Copilot to add API security tests to your test suite
