Overview

AI-generated overview

A hosted MCP server with 26 tools for reading web pages as Markdown, extracting metadata and structure, and checking URLs, domains, SEO, email authentication…

What it does
It exposes 26 tools that fetch and analyze public web pages and URLs. Page tools convert a page to clean Markdown, pull metadata, extract headings, links, images and JSON-LD, detect the tech stack, trace redirects, check TLS certificates and security headers, parse robots.txt, sitemaps and feeds, look up WHOIS/DNS, audit on-page SEO and check up to 100 links. It also grades email authentication (SPF, DMARC, DKIM, MTA-STS, BIMI), inspects SAML and OpenID Connect setups, and offers developer utilities such as cron, regex, color, Unicode and time zone conversion, plus Hyperliquid perpetuals market data.
When to use it
Use it when an assistant needs to read or audit public web content without running a browser: summarizing pages, checking a site's SEO, security headers, certificates, redirects or broken links, verifying email or SSO configuration, or doing small developer conversions.
Requirements
A remote Streamable HTTP endpoint hosted on Apify; nothing runs locally. It needs an Apify API token sent as the Authorization header in the form Bearer , or an Apify account sign-in through Apify's OAuth MCP gateway. Network access to the endpoint and to the target sites is required.
Before you install
The Authorization header carries an Apify API token, so treat it as a secret and avoid sharing client configuration. Calls are billed per successful tool call through the Apify account ($0.001 for check and utility tools, $0.003 for page tools); failed calls are free. Tools only fetch public http/https addresses and refuse private or internal ones, and some sites block automated access. Returned market data is not financial advice.

README

Web Content & URL Tools MCP Server

A remote Model Context Protocol server that gives AI agents 26 tools for reading and checking the web — no browser, no setup, pay only for successful calls.

Read any page as clean Markdown, pull its metadata or structure, detect its tech stack, and check redirects, TLS certificates, security headers, robots.txt, sitemaps, feeds, domains (WHOIS/DNS), SEO, broken links, email authentication (SPF, DMARC, DKIM) and single sign-on (SAML, OpenID Connect). It also includes everyday developer utilities (cron, regex, color, Unicode, time zones) and Hyperliquid perpetuals market data.

Connect

Option 1 — Standby URL + Apify API token

Use your Apify API token as a Bearer token. Works in Claude Desktop, Claude Code, Cursor, VS Code, Windsurf and any MCP client that supports remote servers with headers.

{  "mcpServers": {    "web-content-url-tools": {      "url": "https://avalonai--web-content-url-tools-mcp.apify.actor/mcp",      "headers": { "Authorization": "Bearer <YOUR_APIFY_TOKEN>" }    }  }}

Option 2 — OAuth via mcp.apify.com (no token to copy)

Clients that support MCP OAuth can connect through Apify's hosted MCP gateway and sign in with their Apify account in the browser:

https://mcp.apify.com?tools=avalonai/web-content-url-tools-mcp

Claude Code example:

bash
claude mcp add --transport http web-content-url-tools "https://mcp.apify.com?tools=avalonai/web-content-url-tools-mcp"

Pricing

Pay per successful tool call through your Apify account: $0.001 for check and utility tools, $0.003 for page tools. Failed calls (invalid URL, blocked site, timeout) are free and return a clear error reason.

Good to know

  • Pages are read from the HTML the server sends; sites that render everything in the browser return little text and say so in a warning field.
  • Some sites block automated access; those calls return target_blocked and are not charged.
  • Only public http/https addresses are fetched; private and internal addresses are refused.
