api record

NVIDIA NemoClaw CKG — 55 nodes, 74 edges covering sandboxed AI agent infrastructure. Workflow: search_concepts(query) to resolve a concept, then query_ckg(concept) for its typed subgraph or get_prerequisites(concept) for the full upstream chain. Every result traces to a declared edge — no probabilistic inference.

_ is it live, free and safe measured by this hub
Is ckg-nvidia-nemoclaw live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is ckg-nvidia-nemoclaw free to use?
No — it charges per call, quoted in its own 402 answers.
What tools does ckg-nvidia-nemoclaw have?
6 tools: get_prerequisites, ask_nemoclaw, query_ckg, search_concepts, list_domains, verify_source.
Is ckg-nvidia-nemoclaw 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.

_ usage and payments 30 days

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred from the card: no interface answered anonymously and the card declares security schemes

_ what it can do 6 tools
6 auth-required 6 of 6 classified

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.

  • get_prerequisites reads auth-required never probed

    Full upstream prerequisite chain for a NemoClaw concept.

  • ask_nemoclaw reads auth-required never probed

    Natural-language query over the NemoClaw knowledge graph.

  • query_ckg reads auth-required never probed

    Traverse the NemoClaw knowledge graph from a concept outward.

  • search_concepts reads auth-required never probed

    Find concepts in the NemoClaw CKG by keyword.

  • list_domains reads auth-required never probed

    List all NemoClaw domains in this CKG.

  • verify_source reads auth-required never probed

    Return source URL and SHA-256 hash for a concept node.

_ try it over a2a 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 164f48296d894682.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/164f48296d894682/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.

_ record

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