How to Use the HTML XSS Sanitizer MCP in Mastra AI

Q: How do I add HTML XSS Sanitizer to a Mastra AI workflow using an MCP server?

Install @mastra/mcp and instantiate the MCP client with the server URL. You can then list the tools and spread them directly into your agent's tool configuration to enable sanitizeHtmlhtml execution.

Q: Does HTML XSS Sanitizer support human-in-the-loop approval in Mastra AI?

Yes, you can use the requireToolApproval option on your MCP connection. This forces the agent to pause and request permission before executing sanitizeHtmlhtml on a payload.

Q: What kind of tags does this tool strip out?

The sanitizeHtmlhtml tool strips active scripting elements like script, iframe, and object tags. It also removes inline event handlers like onload or onclick while keeping safe formatting tags.

Strip malicious tags from raw markup inside your Mastra AI automated workflows before saving to database.

Secure multi-step Mastra AI workflows

The `sanitizeHtml_html` tool intercepts untrusted markup early in your automation pipeline to prevent downstream failures. When building complex workflows that ingest user content, a single malicious payload can compromise your entire pipeline. This MCP tool intercepts untrusted markup early in the execution chain. If a step in your workflow fails due to unexpected formatting, Mastra AI handles automatic retries. The sanitization process runs locally, meaning retries do not incur extra API costs or add network latency to your automated runs.

Automated database protection

The `sanitizeHtml_html` tool cleans incoming raw markup before your agent commits it to your database. Saving raw HTML directly to your database is a major security risk. This MCP server lets your agents clean incoming markup before committing it to your storage layer. By calling the tool inside your agent's execution block, you strip out dangerous script tags and event handlers. This keeps your stored data safe without requiring complex, custom regular expressions that are easy to bypass.

Human-in-the-loop validation

The `sanitizeHtml_html` tool filters dangerous elements from rich text before presenting it for human approval. Some workflows require manual approval before publishing rich text to production. You can configure your agent to run the sanitization first, then present the clean markup to a human moderator. This reduces the work for your moderators, as they only review safe, structurally valid HTML. It prevents accidental execution of malicious code in your internal admin dashboards during the review process.

Setup guide

Set up HTML XSS Sanitizer MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All HTML XSS Sanitizer tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "html-xss-sanitizer-mcp-client",
  servers: {
    "html-xss-sanitizer-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "HTML XSS Sanitizer Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to HTML XSS Sanitizer tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent HTML XSS Sanitizer transactions"
);
console.log(result.text);

Install `@mastra/mcp` and instantiate the MCP client with the server URL. You can then list the tools and spread them directly into your agent's tool configuration to enable `sanitizeHtml_html` execution.

Yes, the framework's built-in workflow engine automatically handles retries with exponential backoff. If a network blip occurs, your agent will retry the `sanitizeHtml_html` call without crashing the pipeline.

Yes, you can use the `requireToolApproval` option on your MCP connection. This forces the agent to pause and request permission before executing `sanitizeHtml_html` on a payload.

The `sanitizeHtml_html` tool strips active scripting elements like script, iframe, and object tags. It also removes inline event handlers like onload or onclick while keeping safe formatting tags.

Yes, your raw markup is processed entirely within an isolated, ephemeral sandbox. No data is stored, logged, or transmitted to external servers, keeping your sensitive HTML payloads completely private.
