About Refinery MCP

Refinery MCP is an MCP server that cleans fetched URLs or raw HTML into text for agents and RAG pipelines. It provides word counts and token-savings estimates, while leaving page rendering and crawling to other tools.

Key features

  1. 01Clean URLs through the Refinery Apify Actor
  2. 02Clean HTML fetched by another tool
  3. 03Return cleaned text and word count
  4. 04Estimate token savings locally

Use cases

  1. 01Prepare fetched pages for RAG ingestion
  2. 02Reduce HTML noise before LLM context
  3. 03Check estimated token reduction before embedding

MCP support

Exposes `clean_url`, `clean_html`, and `estimate_savings` as MCP tools. URL cleaning uses the Refinery Apify Actor; savings estimates run locally.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Refinery MCP

Clean HTML before your agent burns tokens.

Landing page · Apify Actor

Refinery MCP wraps the Refinery Apify Actor as an MCP server so Claude, Cursor, and other agents can turn raw HTML or URLs into clean LLM-ready text plus word_count.

Agent pipeline: fetch, Refinery MCP, clean text, RAG

The Problem

Agents are getting good at fetching web pages. The problem is what they fetch:

<html>
  <head>
    <script>gtag("event", "page_view")</script>
    <style>.nav,.cookie,.footer{display:block}</style>
  </head>
  <body>
    <nav>Home · Pricing · Login · Docs · Blog · Careers</nav>
    <aside>Subscribe to our newsletter</aside>

      <h1>How ACME cut support ticket routing time by 63%</h1>
      <p>ACME routes 40,000 monthly support tickets through an AI triage system.</p>
      <p>The team reduced retrieval noise by cleaning HTML before chunking.</p>
    </article>

  </body>
</html>

The model does not need most of that. It needs this:

The team reduced retrieval noise by cleaning HTML before chunking.

Before and after: bloated HTML vs clean LLM-ready text and token savings

Refinery MCP gives your agent a tool for that middle step:

fetch page -> refine HTML -> send clean text to RAG / embeddings / LLM

Why

Agents can fetch pages, but raw HTML is noisy and expensive:

  • scripts, styles, tracking tags
  • nav, footers, cookie banners
  • repeated links and layout markup
  • huge token burn before the model sees the real content

Refinery is the middle step your agent can call before it stuffs web context into a prompt:

fetch/render -> clean/refine -> chunk/embed/answer

It is not a crawler. Use Firecrawl, Crawl4AI, Playwright, browser automation, or your own fetcher when you need rendering. Use Refinery when you already have a URL or raw HTML and want a cheap cleanup pass before the LLM.

When To Use It

Use Refinery MCP when:

  • your agent already fetched a page but got bloated HTML
  • you want a deterministic cleanup step before RAG ingestion
  • you need word_count / token-ish savings before embedding
  • you want to separate crawling from content cleanup

Do not use it as your browser renderer, anti-bot layer, or site crawler.

Tools

clean_url

Fetches a URL through the Refinery Apify Actor and returns dataset rows with clean text and metadata.

Example input:

{
  "url": "https://docs.stripe.com/payments",
  "removeScripts": true,
  "removeStyles": true
}
clean_html

Cleans raw HTML your agent, crawler, or browser session already fetched.

Example input:

{
  "html": "<html><body><nav>Home Pricing Login</nav><article><h1>Vendor security update</h1><p>We now support SOC 2 exports for enterprise accounts.</p></article><footer>Legal Privacy Careers</footer></body></html>",
  "extractMentions": false,
  "extractHashtags": false
}

Example result:

{
  "text": "Vendor security update\n\nWe now support SOC 2 exports for enterprise accounts.",
  "word_count": 10,
  "content_type": "web",
  "language": "en",
  "processing_time_ms": 44.96,
  "success": true
}
estimate_savings

Local helper that compares raw HTML vs cleaned text and estimates token savings. This does not call Apify.

Example output:

{
  "raw_chars": 168,
  "clean_chars": 41,
  "estimated_raw_tokens": 42,
  "estimated_clean_tokens": 11,
  "estimated_token_savings": 31,
  "reduction_pct": 76
}

Install

npx -y @larelabs/refinery-mcp

Set your Apify token:

export APIFY_TOKEN=apify_api_xxx
export REFINERY_ACTOR_ID=larelabs/refinery-html-to-llm-cleaner

Cursor / Claude Desktop config

Use the published package:

{
  "mcpServers": {
    "refinery": {
      "command": "npx",
      "args": ["-y", "@larelabs/refinery-mcp"],
      "env": {
        "APIFY_TOKEN": "apify_api_xxx",
        "REFINERY_ACTOR_ID": "larelabs/refinery-html-to-llm-cleaner"
      }
    }
  }
}

Or run from source during development:

git clone https://github.com/LareLabs/refinery-mcp
cd refinery-mcp
npm install
npm run build
{
  "mcpServers": {
    "refinery": {
      "command": "npm",
      "args": ["run", "dev", "--prefix", "/absolute/path/to/refinery-mcp"],
      "env": {
        "APIFY_TOKEN": "apify_api_xxx"
      }
    }
  }
}

Smoke Test

npm run build
APIFY_TOKEN=apify_api_xxx npm run smoke

The smoke test starts the MCP server over stdio, lists tools, and calls estimate_savings without spending Apify credits.

Example Agent Prompt

Use Refinery MCP to clean this docs page before summarizing it:
https://docs.stripe.com/payments

Return the clean text, word_count, and a short summary. Do not summarize raw HTML.

Another useful prompt:

I fetched this page HTML with Playwright. Use Refinery MCP clean_html before adding it to my RAG ingestion queue. Return the cleaned text and estimated token savings.

Roadmap

  • Glama listing (glama.json added — submit at https://glama.ai/mcp/servers)
  • mcp.so directory PR (pending)
  • Hosted HTTP/SSE MCP transport
  • Batch URL cleanup tool
  • Glama / PulseMCP / FindMCP / mcp.so listings
  • Optional direct REST wrapper for RapidAPI
  • Token savings benchmark page

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
