- Is limitguard live?
- Yes — it answered the hub's last check (checked 24m ago). It answered 98% of checks over the last 30 days.
- Is limitguard free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does limitguard have?
- 9 tools: agent_check, entity_check, lead_verify, seller_preflight, kyb_check, wallet_sanctions, light_check, risk_score, ….
- Is limitguard 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, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 25 doors on this origin, so the chain figures are the operator's. How it is counted.

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.
light_check 0.05 USDC paid never probed
Light company check for an agent: is the company on the NL (KVK) or BE (KBO) register and active, is its EU VAT number valid (VIES), and does its name match the OFAC, EU or UN sanctions lists? Each part says ok, not covered or unavailable. No owners, PEP or address match.
risk_score 0.25 USDC paid never probed
Quick risk score assessment. Faster than full entity check.
verify_wallet reads 0.005 USDC paid never probed
Screen a wallet: OFAC SDN address match, on-chain signals (contract check, native and USDC balance, transaction count, first seen on Base) and named risk rules with up to 3 advice items. On Base, also reports any ERC-8004 agent the wallet owns and its open on-chain reputation as descriptive signals, never scored. Supports EVM and Solana addresses.
agent_check unknown never probed
Agent wallet check in one call: screens an EVM wallet against the OFAC SDN digital-currency address list, reads its Base USDC and ETH balance, looks up its ERC-8004 identity registration (and, given an agent id, that agent's owner and payment wallet) and lists open ERC-8004 feedback, which is not scored. Returns one verdict and each part's status; a part that could not be read says so.
entity_check unknown never probed
Company check: sanctions and country risk on every call; the KVK or KBO register, VAT, domain and IBAN checks depending on the identifiers supplied. Returns a 0-100 score, a cluster and a recommendation.
lead_verify unknown never probed
Lead verify for one NL or BE sales lead: is it a real, active company? Checks the KVK or KBO register and cross-checks what the lead holds: VAT with VIES, mail server and disposable domain, IBAN country and bank (not the holder), and the company name against the OFAC, EU and UN sanctions lists. Returns a verdict, a 0-100 lead score and flags, each with one action. An input not given is not checked.
seller_preflight unknown never probed
Preflight before an agent pays an x402 seller: screens the payTo wallet against the OFAC SDN address list, reads who registered the resource domain and when (RDAP), and screens that company against the OFAC, EU and UN lists. Compares the payTo with the wallet the seller publishes in its 402 and /.well-known/x402, and blocks a lookalike (address poisoning). Returns ok, caution or block with one reason per finding.
kyb_check unknown never probed
Know Your Business verification with sanctions check and company registration.
wallet_sanctions unknown never probed
Free yes/no check of a wallet address against the OFAC SDN digital-currency address list, held locally and refreshed daily: sanctioned, lists, the list date and its freshness, no programmes or entry ids. 10 per caller per UTC day, separate from the name preview, 50 per client IP across API keys. The full wallet screen is POST /v1/mcp/verify-wallet ($0.005 by x402, $0.11 with an API key).
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 id7d98f33029f42a1c.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/7d98f33029f42a1c/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.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
