Chain HTML Cleaning Before Database Insertion

LangChain agents use `sanitizeHtml_html` to intercept raw user input before it hits your database. The agent takes the raw payload, strips out malicious scripts, and passes the safe HTML down the line. You keep the formatting you need without the injection risks.

Trace Sanitization Steps in LangSmith

When your LangChain ReAct agent calls `sanitizeHtml_html`, LangSmith logs the exact input and output. Security operations need visibility. You see exactly which tags the tool stripped out. If a user complains their formatting broke, you have the trace data to figure out why.

Secure Your LangChain MCP Server Workflows

The `sanitizeHtml_html` tool acts as a reliable checkpoint for data moving between external APIs and your internal systems. Building multi-tool agents means data moves quickly. Your agent evaluates the HTML, scrubs the dangerous attributes, and only then proceeds to interact with your other connected services.

Setup guide

Set up HTML XSS Sanitizer MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes HTML XSS Sanitizer tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "html-xss-sanitizer-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent HTML XSS Sanitizer transactions"
    })
    print(result["messages"][-1].content)

Common questions about HTML XSS Sanitizer MCP in LangChain

Install the langchain-mcp-adapters package. Use MultiServerMCPClient to connect to the server URL, then pass the tools directly to your agent.

Yes. If you give a ReAct agent access to the tool, it will recognize raw HTML and clean it before passing it to other tools.

It strips out script tags, onload attributes, and other injection vectors. The tool returns a clean string ready for your application.

The cleaning happens instantly and locally. You will not notice any latency when your agent calls it.

No. The server processes raw HTML strings in memory and immediately drops them. Your user-generated content is never logged or saved to disk.
