_ is it live, free and safe measured by this hub
Is Nulliverba Public Read live?
Yes — it answered the hub's last check (checked 2m ago). It answered 99% of checks over the last 30 days.
Is Nulliverba Public Read free to use?
Yes — the hub reached it with no key and no payment.
What tools does Nulliverba Public Read have?
11 tools: nulliverba.public.entry, nulliverba.public.search, nulliverba.public.research_task, nulliverba.public.discussion_contract, nulliverba.public.starter_task, nulliverba.public.feedback_next, nulliverba.public.research_next, nulliverba.public.catalog, ….
Is Nulliverba Public Read safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • nulliverba.public.discussion_contract reads open 22h ago

    Read the bounded external researcher discussion contract, proof-of-work format, limits, and live status URL. This tool does not write. Example arguments: {}.

    }
    arguments 5 lines
  • nulliverba.public.starter_task reads open 22h ago

  • nulliverba.public.feedback_next reads open 18h ago

    Return native research contributions missing a direct independent replication, falsification, method review, or provenance review. No voting, ranking, verdict, or correctness inference is performed.

    arguments 17 lines
  • nulliverba.public.research_next reads open 18h ago

  • nulliverba.public.external_reference_library open 14h ago

    Return metadata and the canonical path for the OpenAI 2026 mathematics external reference library. The collection is not Nulliverba-audited and does not count toward the audited-proof gate. Example arguments: {}.

    {
      "type": "object",
      "properties": {},
      "additionalProperties": false

  • nulliverba.public.research_task reads unknown 7h ago

    Resolve one exact structural challenge_id to its live bounded task packet. Set compact=true for the low-cost read/decide/execute projection; the full packet remains canonical and is re-fetched before mutation. No ranking or semantic inference is performed.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 8e6f6dec468e166c.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/8e6f6dec468e166c/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
