Overview

AI-generated overview

Web2MD fetches web pages through the RapidAPI Web2MD service and returns clean Markdown, plain text, metadata or token-bounded RAG chunks.

What you can do
  • Fetch a page and return its main content as Markdown, text or JSON, with optional links, images and tables
  • Split a page into heading-aware chunks sized in tokens, with overlap, for RAG and embeddings
  • Convert raw HTML you already have into Markdown or plain text
  • Read a page's title, author, date, description, site name, language and reading time
When to use it
Useful when an assistant needs readable page content or RAG-ready chunks without writing its own extraction pipeline, and when a hosted extraction service with a free monthly quota is acceptable.
Requirements
Runs locally via npx (npm package web2md-rag-mcp) and needs Node.js 22 or newer. Requires a RAPIDAPI_KEY environment variable from a RapidAPI subscription to Web2MD; the BASIC plan is free with 500 requests per month. Network access to the RapidAPI gateway is required.
Before you install
The RAPIDAPI_KEY secret is sent to the RapidAPI gateway, and every fetched URL is processed by that third-party service. Paid plans exist above the free tier, and quotas or rate limits can be exhausted. Pages are fetched server-side, so private or internal addresses are blocked and robots.txt is respected.

Installation

In SourceWeft

  1. Open Web2MD in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

README

Web2MD MCP server

An MCP server that turns any web page into clean Markdown, plain text or token-bounded RAG chunks, using the Web2MD API on RapidAPI.

[npm] [CI]

What it does

  • read_url: fetch a web page and return its main content as Markdown or plain text, without nav, ads or boilerplate.
  • chunk_url: fetch a web page and split it into heading-aware chunks sized in tokens, for RAG and embeddings.
  • convert_html: convert raw HTML you already have into Markdown or plain text.
  • page_metadata: get a page's title, author, published date, description and similar fields without the full content.

Setup in 3 steps

  1. Subscribe to Web2MD on RapidAPI. The BASIC plan is free and includes 500 requests per month.
  2. Copy your X-RapidAPI-Key from the Endpoints tab of the listing.
  3. Add the server to your client.

Requires Node.js 22 or newer.

Claude Code:

bash
claude mcp add web2md -e RAPIDAPI_KEY=your-key -- npx -y web2md-rag-mcp

Claude Desktop (claude_desktop_config.json) and Cursor (~/.cursor/mcp.json) use the same JSON:

json
{  "mcpServers": {    "web2md": {      "command": "npx",      "args": ["-y", "web2md-rag-mcp"],      "env": { "RAPIDAPI_KEY": "your-key" }    }  }}

Windsurf: put the same block in ~/.codeium/windsurf/mcp_config.json.

Errors

Tool errors look like Web2MD error [code]: message. Input-validation failures (a bad URL, out-of-range numbers) come from the MCP SDK as MCP error -32602: Input validation error ... instead.

CodeMeaning
missing_keyRAPIDAPI_KEY is not set
invalid_keyRAPIDAPI_KEY contains characters not allowed in an HTTP header, often a pasted newline
rapidapi_authRapidAPI rejected the key, or you are not subscribed
rapidapi_quotaYour plan's quota or rate limit is used up
invalid_requestThe request failed validation (HTTP 422)
invalid_url400: not http/https, has credentials, no host, bad port, or longer than 2048 chars
blocked_destination400: host resolves to a private, loopback, link-local or metadata address; port not 80/443; localhost/.local/.internal. Applies to every redirect
dns_error400: the host does not resolve
robots_disallowed403: the site's robots.txt disallows the web2md user agent for that path
page_too_large413: page larger than 5 MB
unsupported_content_type415: not HTML
no_content422: fewer than 10 words of main content, often a JavaScript-only page
host_rate_limited429: per-target-site limit that protects the sites fetched. It is not your quota
target_blocked502: the site answered 401/403/429/503, often a bot wall
target_error502: the site answered another 4xx/5xx
fetch_failed502: could not connect, or TLS failed
too_many_redirects502: more than 5 redirects
fetch_timeout504: the fetch took more than 15 s
timeoutThe Web2MD request timed out
network_errorThe request could not reach the API
bad_responseThe API returned a non-JSON success response
http_<status>Any other HTTP failure, with a short snippet of the response
internal_errorAn unexpected error inside the MCP server

Privacy
