How to validate form input payloads with your AI

Connect this MCP to your agent to scrub incoming web form data. It handles the heavy lifting of cleaning HTML so you don't have to write custom regex for every input.

Short answer

How do I validate form input payloads with my AI?

Your agent passes raw HTML strings through the sanitizeHtml_html tool to strip out dangerous scripts and malicious tags. This ensures the data hitting your database is clean and safe from XSS attacks. You'll see the results of this cleaning process in the following breakdown.

The results of sanitization.

Where the cleaned data lands.

The AI processes the payload and directs the output based on your instructions.

CLEANED

Safe HTML payloads

The AI removes scripts and dangerous attributes. You get a string containing only the safe, intended HTML tags.

REJECTED

Flagged injection attempts

If the payload is too dangerous, the AI identifies the threat. You receive a notification to block the request.

LOGGED

Audit trail creation

The AI can summarize the cleaning actions. You get a report of what was stripped from the input.

HUMAN

Manual review needed

If the AI finds ambiguous or highly complex nested tags, it flags the payload for you to inspect manually.

The workflow

What your AI does when the payload arrives.

The agent acts as a security layer between your user input and your backend.

  1. Inspect payload

    Your agent reads the raw HTML string sent from the web form to identify potential script tags.

    sanitizeHtml_html

  2. Strip malicious code

    The agent runs the sanitization tool to remove any XSS vectors found in the input.

    sanitizeHtml_html

  3. Validate structure

    The AI checks if the remaining HTML matches your expected schema for that specific form field.

    sanitizeHtml_html

  4. Deliver safe string

    The agent provides the sanitized version of the payload, ready for your database or application logic.

FAQ

How this task behaves.

  • 01

    Does the AI automatically save the cleaned HTML to my database?

    No. The AI only performs the sanitization. You must take the cleaned output and send it to your database yourself.

  • 02

    Can the AI delete the original malicious payload?

    No. The tool creates a new, clean version of the string. It does not modify or delete your original source data.

  • 03

    Will it block all HTML tags?

    No. It only removes tags and attributes that are known to be used for injection attacks.

  • 04

    Can I use this to prevent SQL injection?

    No. This tool is specifically for cleaning HTML to prevent XSS. You need different methods for SQL injection.

  • 05

    Does the AI decide which tags are safe?

    The AI uses the logic provided by the sanitizeHtml_html tool to determine what to strip.
