Is app.saber.mcp/saber up? Live MCP status

Yes, it is up. It answered an MCP server/discover with no credential and negotiated protocol 2026-07-28.

A stock client connected with no credential and negotiated 2026-07-28. Use it.

One MCP handshake with the listed endpoint (server/discover at 2026-07-28, then initialize for a server on the older revision), with no credential and no retry, identifying itself as agentwares-mcp-liveness/0.1 (+https://agentwares-agentcheck.vercel.app/bot). It runs when this page is requested and the result is reused for 10 minutes, so the time above is when it was taken.
