Convert raw HTML to clean Markdown via html-to-markdown-mcp (npx)
intentconvert raw HTML content or fetch a URL and convert its HTML to clean, readable Markdown — preserving headings, bold, links, lists, and code blocks — using html-to-markdown-mcp through npx, no API key neededconstraints

html-to-markdown-mcp converts raw HTML strings or fetches URLs and converts them to clean Markdown. Unlike mcp-server-fetch (which only accepts URLs), this server also accepts raw HTML content directly — useful when you already have HTML from another source (DOM scrape, API response, template output). Powered by Turndown.js.

Recipe: Convert raw HTML to Markdown via html-to-markdown-mcp
Setup
npx -y html-to-markdown-mcpTransport: stdio (NDJSON). Server: html-to-markdown v1.0.0, powered by Turndown.js.
Tool inventory
One tool: html_to_markdown
html(string, optional) — raw HTML content to converturl(string, optional) — URL to fetch and convertincludeMetadata(boolean, optional) — include source/timestamp headermaxLength(number, optional) — truncate output
Either html or url must be provided. This is the key differentiator from mcp-server-fetch: you can pass raw HTML directly, not just URLs.
Example: raw HTML → Markdown
Request:
{"name":"html_to_markdown","arguments":{"html":"<div><h1>Hello World</h1><p>This is a <strong>bold</strong> paragraph with a <a href=\"https://example.com\">link</a>.</p><ul><li>Item 1</li><li>Item 2</li><li>Item 3</li></ul><pre><code>const x = 42;</code></pre></div>"}}Response:
# Hello World
This is a **bold** paragraph with a [link](https://example.com).
- Item 1
- Item 2
- Item 3
\`\`\`
const x = 42;
\`\`\`When to use
- You already have HTML from a DOM scrape, API response, or template render
- You need to strip HTML tags while preserving semantic structure
- mcp-server-fetch only takes URLs; this takes raw HTML too
Gotchas
- Default metadata header adds "Source: Unknown" and timestamp — pass
includeMetadata: falseto suppress - Server prints startup banner to stderr ("HTML to Markdown MCP Server running on stdio") — safe to ignore
