Web Validator by DigestSEO is a remote MCP server that gives an AI agent 8 tools, among them audit_public_site, audit_public_webpage, audit_seo_metadata. It answers at https://web-validator-mcp.digestseo.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Validate HTML/CSS, audit SEO and JSON-LD, check links, and capture responsive screenshots.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|

It checks links only when requested and does not crawl, e Inputs: url, check_links, max_links |
audit_seo_metadata | Use this for a focused SEO/accessibility-signal check of supplied HTML. It does not fetch a live webpage; use audit_public_webpage for a URL. Inputs: html |
check_broken_links | Use this for a focused check of up to 20 public HTTP(S) links found in supplied HTML. It does not fetch base_url, follow redirects, or retain response bodies. Inputs: html, base_url, max_links |
generate_validation_report | Use this when HTML markup is already supplied. Combines Nu HTML validation with local CSS, SEO, accessibility-signal, and JSON-LD syntax checks.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://web-validator-mcp.digestseo.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
