How to verify input validation with your AI

Connect this MCP to your agent to audit code for input handling flaws. Once connected, your AI can check if your logic actually enforces the security constraints you expect.

Short answer

How can I make sure my AI is actually validating inputs?

You use the Security Audit Prover to force your agent to run specific security checks against your code. It uses the validate_security_audit tool to confirm that your regex patterns and sanitization libraries are correctly applied to all user-facing inputs. You'll see exactly where your logic holds up or fails.

Audit results.

Where your findings land.

The AI processes your code and categorizes the results based on the audit.

CRITICAL

Immediate security gaps

The AI identifies missing sanitization or weak regex that allows injection. You get a direct list of where your input validation fails.

WARNING

Suboptimal constraints

The agent flags regex patterns that are too broad or sanitization libraries that are outdated. This helps you tighten your logic.

PASS

Validated logic

When the code meets your specific security requirements, the AI confirms the validation is active and correct.

HUMAN

Manual review needed

If the AI finds ambiguous logic that it can't definitively prove, it flags the section for you to inspect manually.

The workflow

What your AI does when the audit request arrives.

Your agent takes your code and runs it through a specialized security check.

  1. Analyze input logic

    The agent scans your source code to locate every point where user input enters the system.

    validate_security_audit

  2. Verify regex constraints

    The AI checks if the identified regex patterns match the strict security rules you defined.

    validate_security_audit

  3. Check sanitization

    It confirms that the specific sanitization libraries you've chosen are being called on all incoming data.

    validate_security_audit

  4. Report findings

    The agent compiles a report showing where validation is missing or where the constraints are too weak.

  • Run a security audit on my auth.py file to ensure all inputs use the required regex.

  • Check the validation logic in my user_registration.js file for proper sanitization.

  • Audit the input handling in my API controller to see if it meets my security constraints.

  • Verify that the regex used in my contact form handler is actually preventing script injection.

FAQ

How this task behaves.

  • 01

    Can the AI fix my code automatically?

    No. The AI identifies the flaws and proves whether the validation exists, but you must manually apply the fixes to your code.

  • 02

    Does the AI change my regex patterns?

    No. The AI only checks your existing patterns against your requirements to see if they pass or fail.

  • 03

    Can I audit files that aren't in my current workspace?

    Yes, as long as you provide the agent with the path or access to those files.

  • 04

    Will it check for vulnerabilities in third-party libraries?

    It checks if you are calling your sanitization libraries correctly, but it does not perform a deep vulnerability scan of the libraries themselves.

  • 05

    How does it know which regex to use?

    You must tell the agent which specific regex constraints or sanitization rules it should be looking for during the prompt.
