Compatible with every major AI agent and IDE
What is the HTML XSS Sanitizer MCP Server?
If you ask an AI to 'clean this HTML before saving it', it will likely fail to catch obfuscated XSS vectors hidden in Base64 or obscure event handlers. LLMs do not have native rendering engines to test payloads. This MCP provides an enterprise-grade security shield for agents that handle public inputs.
The Superpowers
- Surgical Cleaning: Uses
sanitize-htmlto strip dangerous tags (,) and maliciousonloadevents. - Zero-Trust Input: Enforces a strict whitelist of safe tags, ensuring that what goes into your database cannot execute harmful code in a browser.
Built-in capabilities (1)
Pass the raw HTML and receive clean, safe HTML with dangerous tags and attributes stripped. Strips malicious XSS vectors and unsafe tags from HTML payloads before they are saved to a database
Why Mastra AI?
Mastra's agent abstraction provides a clean separation between LLM logic and HTML XSS Sanitizer tool infrastructure. Connect 1 tools through Vinkius and use Mastra's built-in workflow engine to chain tool calls with conditional logic, retries, and parallel execution. deployable to any Node.js host in one command.

Why teams choose Vinkius for HTML XSS Sanitizer in Mastra AI
The HTML XSS Sanitizer MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 1 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Mastra AI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
HTML XSS Sanitizer for Mastra AI
Every tool call from Mastra AI to the HTML XSS Sanitizer MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
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, <img> tags are whitelisted, but only with safe attributes like src and alt.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
