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.

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.

This is the source of the Apify Actor that hosts the MCP server. It is a thin connector: each tool forwards the request to the Web Content API and returns the JSON result.
