Linkheft — questions

Answers built from our own checks of this server.

What can Linkheft do?

It exposes 2 tools, read directly from the server on our last check. Among them: dataset_info, domain_authority. 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 Linkheft working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 178 of 178 checks got a reply (100.0%), average response time 87 ms. The bar chart above shows every period we have measured.

How do I connect Linkheft?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Linkheft need an API key?

No. Linkheft completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Linkheft?

It answers our handshake in 87 ms on average, which is faster than 88% 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.
