Available tools 1

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

lint
lint_hreflang
Lint hreflang annotations for international SEO. Accepts pasted text (not a URL; this tool never fetches anything): page HTML with <link rel="alternate" hreflang> tags, an XML sitemap with xhtml:link alternates, or a JSON set {"pages":[{"url","canonical","alternates":[{"hreflang","href"}]}]}. Checks language/script/region codes, x-default, self-reference, canonical conflicts, duplicates and reciprocal return links. Returns valid true/false, counts, the codes found, and up to 25 issues with paths, messages and suggested fixes. Read-only. Same engine as the HrefGate JSON API (POST /api/lint).

HrefGate — questions

Answers built from our own checks of this server.

What can HrefGate do?
It exposes 1 tools, read directly from the server on our last check. Among them: lint_hreflang. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is HrefGate working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 105 ms. The bar chart above shows every period we have measured.
How do I connect HrefGate?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does HrefGate need an API key?
No. HrefGate completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is HrefGate?
It answers our handshake in 105 ms on average, which is faster than 91% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
