- Is NumProof live?
- Yes — it answered the hub's last check (checked 58m ago). It answered 99% of checks over the last 30 days.
- Is NumProof free to use?
- Not measured yet.
- What tools does NumProof have?
- 4 tools: audit_rows, diff_rows, verify_claim, covenant_rules.
- Is NumProof 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.

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
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.
audit_rows reads unknown never probed
Audit spreadsheet-like rows for footing, balance-sheet ties, common margins, and cell provenance.
{ "type": "object", "required": [ "rows" ], "properties": { "rows": { "type": "array" } } }arguments 11 linesdiff_rows reads unknown never probed
Compare two report versions by numeric row labels with provenance.
{ "type": "object", "required": [ "rows_before", "rows_after" ], "properties": { "rows_after": { "type": "array" }, "rows_before": { "type": "array" } } }arguments 15 linesverify_claim reads unknown never probed
Exactly verify a math/finance claim (VERIFY/REFUTE/ABSTAIN) with a counterexample when false. Use before trusting any AI-produced number, sum, percentage, or formula.
{ "type": "object", "required": [ "claim" ], "properties": { "claim": { "type": "string" } } }arguments 11 linescovenant_rules reads unknown never probed
Evaluate threshold/covenant rules over spreadsheet-like rows with provenance. Use either rules or rule_pack.

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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id95797e0cb8f5cde8.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/95797e0cb8f5cde8/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.
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.
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.
