How to Use the HTML to Text Extractor MCP in LangChain

Q: How do I add the HTML to Text Extractor MCP Server to my LangChain agent?

Install the langchain-mcp-adapters package and connect to the Vinkius endpoint. Once connected, pull the tools via client.gettools() and pass them directly to your agent constructor.

Q: Does this HTML to Text Extractor MCP Server support LangSmith tracing?

Yes, every call to the extracttext tool is fully observable. LangSmith records the exact execution latency and token savings automatically, giving you clear metrics on your scraping efficiency.

Q: Can I use this HTML to Text Extractor MCP Server with other LangChain integrations?

Yes, you can chain the clean plain-text output from the extracttext tool directly into vector stores, document loaders, or SQL databases within the same workflow.

Feed clean, stripped text directly into your LangChain reasoning loops without wasting tokens on raw HTML markup.

Perplexity

Strip heavy DOM markup inside LangChain chains

The `extract_text` tool takes raw HTML and strips out script tags, style sheets, and boilerplate elements instantly. Your LangChain agents get clean, structured text to process instead of drowning in minified CSS and script blocks. This direct extraction saves up to 95% of your token budget on every web-scraping step. You pass clean strings directly to subsequent chain links, preventing context window bloat before your LLM even starts analyzing the content.

Trace clean tool outputs with LangSmith

The `extract_text` tool integrates directly into your ReAct agent pipelines as a standard run step. LangSmith captures the inputs and outputs, showing you the exact raw HTML payload and the resulting clean text. You see the exact reduction in token usage inside your tracing dashboard. There is no guesswork about what went into the prompt, making debugging multi-step scraping chains straightforward.

Feed clean text to your LangChain agent pipelines

The `extract_text` tool acts as a pre-processing filter inside autonomous reasoning loops. Your agent decides when to pull a webpage and immediately cleans it before passing it to synthesis tools. Combining this MCP Server with database or vector store integrations keeps your entire pipeline fast. You avoid sending useless script tags to your vector databases, keeping your storage clean and your retrieval accurate.

Setup guide

Set up HTML to Text Extractor 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 to Text Extractor 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-to-text-extractor-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 to Text Extractor transactions"
    })
    print(result["messages"][-1].content)
