A failure counts as down time only when a second check five minutes later fails too. How we check

Connect to the publisher's own endpoint

Run in a terminal:

claude mcp add --transport http gembook https://gembook.xyz/api/mcp/mcp

Every step above as one Markdown text, for an assistant installing it for you.
