The owner asked us not to check this server.

We stopped reaching out to it on 20 Aug 2026, so there is no uptime, no tool list and no findings on this page. What stays is what the public MCP registry says about it.

Any owner can ask for the same — see how the mcpbeat bot works.

What changed 1

Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 9 August 2026. No other catalogue keeps this.
