## Description

If you ask an AI to clean up some HTML, it might miss the sneaky stuff. LLMs do not have native rendering engines, so they can't actually see how a hidden Base64 string or a weird event handler might execute in a browser. This Connector acts as a security gate for your data. When your agent handles public inputs like comments or profile bios, it uses this tool to scrub the content first. It follows a strict whitelist, so only the safe tags you want actually make it through. You can rely on it to catch the payloads that standard text processing misses. It is one of the many tools you can find in the Vinkius catalog to keep your infrastructure secure without having to write complex regex for every single input. It turns a risky task into a predictable security step.

## Tools

### sanitizeHtml_html
Strips malicious XSS vectors and unsafe tags from HTML payloads before they are saved to a database. This ensures your data stays clean and safe for all users.

## Prompt Examples

**Prompt:** 
```
Check this comment for scripts: `<p>Hi</p><script>alert(1)</script>`
```

**Response:** 
```
✅ **Sanitized:** `<p>Hi</p>`
```

**Prompt:** 
```
Clean this bio: `<b>Hello</b> <iframe src='malicious.com'></iframe>`
```

**Response:** 
```
✅ **Cleaned:** `<b>Hello</b>`
```

**Prompt:** 
```
Make this blog post safe: `<div>Content</div><img src='x' onerror='alert(1)'>`
```

**Response:** 
```
✅ **Safe Version:** `<div>Content</div><img src='x'>
```

## Capabilities

### Strip dangerous tags
Automatically removes <script> and <iframe> elements from your HTML.

### Clean event handlers
Deletes malicious onload events and other unsafe attributes from your payloads.

### Enforce tag whitelists
Ensures only approved HTML elements are saved to your database.

### Neutralize XSS vectors
Stops obfuscated scripts from executing in the user's browser.

### Process raw HTML
Converts messy user input into safe, renderable strings.

## Use Cases

### Cleaning forum comments
A user submits a comment with a hidden script. The agent uses sanitizeHtml_html to strip it before it goes live.

### Sanitizing profile bios
Someone tries to inject an iframe into their bio. The tool removes it automatically to keep the page safe.

### Safe blog content
An editor pastes a messy HTML snippet. The agent cleans it so it's safe to display without breaking the layout.

### Review systems
A customer leaves a review with an onload event. The Connector neutralizes the threat instantly.

## Benefits

- Stop XSS attacks by using sanitizeHtml_html to remove scripts before they hit your database.
- Reduce manual security reviews by automating the scrubbing of every user-submitted HTML field.
- Maintain data integrity by ensuring only whitelisted tags are stored in your production environment.
- Protect your users from malicious redirects and popups by stripping out iframe elements.
- Simplify your backend logic since your agent handles the heavy lifting of input validation.

## How It Works

The bottom line is that your AI agent can handle raw user input without risking a security breach.

1. Pass the raw, untrusted HTML string to the Connector.
2. The Connector runs the content through a whitelist-based filter to strip dangerous tags.
3. You receive a clean string ready for database insertion.

## Frequently Asked Questions

**Does the HTML XSS Sanitizer MCP stop scripts?**
Yes, it strips out <script> tags and other dangerous elements like <iframe> to prevent them from running in a browser.

**Can I use this for user comments?**
It's perfect for comments because it cleans the HTML while keeping safe tags like <p> or <b> intact.

**Is it better than just asking an AI to clean the text?**
Yes, because LLMs can't see how code actually renders, while this tool uses a real engine to catch hidden XSS vectors.

**What happens to the safe parts of my HTML?**
Tags on the whitelist are kept exactly as they are, while everything else gets removed.

**Does it work on Base64 encoded scripts?**
It's designed to catch many common obfuscation techniques that standard text filters miss.

**How does it protect my database?**
It cleans the data before it's saved, so your database never stores malicious payloads in the first place.

**Does it remove CSS?**
By default, it removes unsafe styles but leaves the structure intact.

**Is it better than asking the LLM to do it?**
Absolutely. LLMs are easily bypassed by obfuscated XSS payloads. This engine relies on strict deterministic whitelisting.

**Are images allowed?**
Yes, `` tags are whitelisted, but only with safe attributes like `src` and `alt`.
