Opuslog does not always answer

Over the last week it answered 19.6% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Opuslog — questions

Answers built from our own checks of this server.

Is Opuslog working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 13 of 90 checks got a reply (14.4%), average response time 1992 ms. The bar chart above shows every period we have measured.
Is Opuslog still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
The registry lists Opuslog as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Opuslog?
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 Opuslog need an API key?
No. Opuslog completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
