clean-markdown-mcp

clean-markdown-mcp

An MCP server that turns any URL into clean, LLM-ready Markdown — no ads, no nav bars, no cookie banners, no scripts.

Built for RAG pipelines and AI agents, where junk in the input means junk in the output.

          Markdown is a lightweight markup language for creating
          formatted text using a plain-text editor...

Install

npm install -g clean-markdown-mcp

Related MCP server: urltomarkdown-mcp

Use it with Claude Desktop

Add this to your claude_desktop_config.json:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

  • Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "clean-markdown": {
      "command": "npx",
      "args": ["-y", "clean-markdown-mcp"]
    }
  }
}

Restart Claude Desktop, then ask it to "scrape https://example.com to Markdown."

Works the same way in Cursor, Windsurf, or any other MCP client — point it at the clean-markdown-mcp command.

The tool it exposes

scrape_url

Parameter

Type

Description

url

string

The page to scrape. Must be http:// or https://.

includeLinks

boolean

Keep hyperlinks in the Markdown. Default true. Set false for cleaner prose.

renderJs

boolean

Load the page in a real browser first, for JavaScript-built sites. Default false. Requires Playwright — see below.

Returns the page title, source, word count, and the clean Markdown.

How the cleaning works

  1. Fetch — with a 20-second timeout, a 5 MB size cap, and redirects validated at every hop.

  2. Clean — runs Mozilla Readability, the engine behind Firefox Reader View, to isolate the real article and discard navigation, sidebars, ads, and comment sections.

  3. ConvertTurndown renders it as GitHub-flavoured Markdown, preserving headings, lists, tables, and code blocks.

If a page isn't article-shaped, it falls back to a cleaned <body> rather than failing, so you still get usable text.

JavaScript-heavy sites (optional)

Some sites build their content with JavaScript after loading. A plain fetch returns almost nothing for those. To handle them, install Playwright once:

npm install playwright && npx playwright install chromium

Then pass renderJs: true. The difference on such a page is dramatic:

Mode

Result

Default

~3 words — just navigation links

renderJs: true

~190 words — the full content

Playwright is not a dependency of this package, so a normal install stays small and fast. Without it, renderJs returns a clear message telling you how to enable it.

Security

The scraper refuses private, loopback, and link-local addresses — including cloud metadata endpoints like 169.254.169.254 — and re-validates every redirect hop. This matters because an MCP server runs on your machine, with access to your local network.

Need to scrape at scale?

This package handles one page at a time, locally. For batch scraping, hosted JavaScript rendering, and a pay-per-page API with no infrastructure to run, the same engine is available as a hosted Actor:

Known limitations

  • Some sites block automated traffic. That's a site policy, not a bug here.

  • Non-UTF-8 pages may render with garbled characters.

  • No robots.txt enforcement — you are responsible for how you use it.

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Since no annotations are present, the description carries the full burden. It discloses that the tool strips navigation, ads, cookie banners, scripts, and other boilerplate, and outputs clean Markdown. This gives the agent meaningful behavioral expectations, though it does not cover error handling or rate limits, which would be desirable but not essential for this tool type.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the core functionality, and contains no fluff. It efficiently conveys the behavior and use case.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity and the fully documented schema, the description covers the essential context. It clarifies the return format (Markdown) and the cleaning behavior, which is important because there is no output schema. The description is complete for this tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already fully documents each parameter. The description adds no extra meaning beyond what the schema provides for url, renderJs, and includeLinks. The baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb-resource pair: 'Fetch any web page and return its main content as clean, readable Markdown.' It also specifies the cleanup behavior, making the tool's purpose unmistakable. No sibling tools exist, so no differentiation is needed.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides a clear usage context: 'Ideal for feeding article or documentation content to an LLM.' It implies the tool is for extracting clean main content, but does not explicitly mention when not to use it or list alternatives (none exist). The use case guidance is sufficient.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.4/5.0
Disambiguation5/5

With only a single tool, there is no possibility of confusion or overlap. The tool's purpose is clear and distinct by definition.

Naming Consistency5/5

The tool name 'scrape_url' follows a clear verb_noun pattern, which is consistent with common MCP naming conventions. With only one tool, the pattern is trivially consistent.

Tool Count4/5

The server has only 1 tool, which is below the typical 3-15 range. However, it is appropriately scoped for a highly focused purpose: fetching and converting web pages to clean markdown. The single tool fully covers the server's stated function.

Completeness5/5

The domain is 'clean-markdown', and the single tool provides a complete lifecycle: it fetches any web page and returns clean markdown, covering all necessary functionality. There are no obvious gaps for the stated purpose.
