How to Use the HTML to Text Extractor MCP in LlamaIndex

Q: How does the HTML to Text Extractor MCP Server improve my LlamaIndex search results?

The extracttext tool removes HTML tags, inline scripts, and CSS blocks that distort vector embeddings. By indexing only plain text, your semantic search retrieves highly relevant chunks instead of layout boilerplate.

Q: How do I configure the HTML to Text Extractor inside LlamaIndex?

Use llama-index-tools-mcp to initialize the BasicMCPClient pointing to your Vinkius endpoint. Convert it to a tool spec with McpToolSpec and pass it to your FunctionAgent.

Q: Can I run this HTML to Text Extractor MCP Server asynchronously in LlamaIndex?

Yes, you can load the MCP tools asynchronously using totoollistasync(). This keeps your ingestion pipelines non-blocking when processing hundreds of HTML pages concurrently.

Index clean, stripped text instead of raw markup for accurate LlamaIndex vector searches.

Perplexity

Ground your LlamaIndex RAG on clean text

The `extract_text` tool strips the raw HTML of its tags, style sheets, and scripts to prepare clean plain text for indexing. This ensures your vector store indexes only semantic content, not boilerplate code. You avoid indexing thousands of lines of useless CSS classes and script configurations. This makes your semantic searches highly accurate because the embeddings represent real content rather than structural noise.

Lower indexing costs with this MCP Server

The `extract_text` tool cuts down the size of your raw web documents by up to 95% before chunking begins. LlamaIndex processes fewer tokens during the embedding generation phase, lowering your API costs. Smaller chunks mean you fit more relevant context into the LLM's prompt window during retrieval. You get clean, dense information blocks that improve synthesis and eliminate hallucinations.

Build clean knowledge bases from raw web pages

The `extract_text` tool integrates directly into your data ingestion pipelines. Your LlamaIndex agents run the extraction, then convert the output plain text into standard Document objects. This setup works for live scraping or batch processing of saved web archives. You build a searchable knowledge base grounded in actual text content, completely free of markup clutter.

Setup guide

Set up HTML to Text Extractor MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all HTML to Text Extractor MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to HTML to Text Extractor tools.",
)
response = await agent.run("List recent HTML to Text Extractor data")

Yes, you can load the MCP tools asynchronously using `to_tool_list_async()`. This keeps your ingestion pipelines non-blocking when processing hundreds of HTML pages concurrently.

The tool flattens tables and nested lists into clean text blocks. While it drops the visual layout, it preserves the words and numbers so your index can still search them.

Processing occurs in a secure, zero-trust V8 sandbox managed by Vinkius. Your HTML strings are parsed in memory, discarded immediately after extraction, and never written to persistent storage.
