Is com.rubrkit/rubrkit up? Live MCP status

No, it is not answering as an MCP server. HTTP 400.

The endpoint did not answer as an MCP server: HTTP 400. Do not spend a call on 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.

Live status every few hours: Wellknown

Monthly census, 6 October 2026

The census sends the same request to every remote listing in the official registry once a month. On 6 October 2026 this one answered a stock client with no credential. Every listing’s result: index.ndjson (what the files hold: index.meta.json).

A2A against v1.0.1, the server card against the MCP Server Card schema (SEP-2127), the card at SEP-1649’s location against the shape it has, the key directory against the Web Bot Auth draft of 1 September 2026.
