api record

Paid tools settle per call in USDC on Base. Call tools/list (free) to see prices, then invoke tools/call; an unpaid call returns HTTP 402 carrying BOTH an x402 challenge (PAYMENT-REQUIRED header -> retry with PAYMENT-SIGNATURE) and an MPP challenge (WWW-Authenticate: Payment -> sign the EIP-3009 authorization with nonce = keccak256(challenge.id + challenge.realm) -> retry with 'Authorization: Payment <base64url credential>', or place the credential at params._meta['org.paymentauth/credential']; the receipt returns in Payment-Receipt / result._meta['org.paymentauth/receipt']).

_ is it live, free and safe measured by this hub
Is sentinel402-agent-tools live?
Yes — it answered the hub's last check (checked 8m ago). It answered 99% of checks over the last 30 days.
Is sentinel402-agent-tools free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does sentinel402-agent-tools have?
6 tools: service_info, get_live_data, scan_batch, scan_prompt_injection, audit_compliance, scan_for_pii.
Is sentinel402-agent-tools 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.

  • get_live_data reads 0.003 USDC paid 5h ago

    Fetches current, citable data from primary sources: crypto spot prices, weather, recent GitHub commits, live sports scores, FX reference rates, Hacker News front page + search, Wikipedia summaries, stock/ETF quotes, news headlines, IP geolocation, npm and PyPI package metadata, and ENS name resolution. Returns the answer as text plus structured fields and a source URL you can cite. Data is cached per collection, so it is cheap and fast.

  • scan_batch reads 0.05 USDC paid 5h ago

    Scans up to 20 texts or JSON objects in ONE tool call for ONE price ($0.05 — cheaper than scanning them individually). Returns a per-item decision, risk score, findings with redacted samples and sanitized copies, plus an aggregate verdict across the batch. Use it when an agent processes a dataset, a message thread or a folder of files and each outbound item must be checked first.

  • scan_prompt_injection reads 0.01 USDC paid 21h ago

    Checks untrusted content (web pages, tool outputs, emails, user messages) for prompt-injection markers BEFORE it enters your context window: instruction overrides, system-prompt exfiltration attempts, invisible Unicode tag payloads, zero-width steganography, fake role delimiters, jailbreak language, credential/fund exfiltration instructions, HTML-comment directives, markdown image beacons and obfuscated blobs. Returns allow/review/block, a 0-100 risk score and the matched patterns with excerpts. Regex-structural detection, no model in the loop.

  • audit_compliance reads 0.03 USDC paid 21h ago

    Runs the full detection engine over a text or JSON payload and maps every finding onto four framework profiles — PCI DSS 4.x (card data), GDPR (personal data), HIPAA Safe Harbor (health identifiers), secrets hygiene (SOC 2 CC6-style). Returns an overall pass/fail verdict, per-framework breakdowns naming the exact triggering rules, a 0-100 risk score and a sanitized copy safe to forward. Built for compliance agents and CI gates. Not legal advice — the report says so and lists the rules behind every verdict.

  • scan_for_pii reads 0.02 USDC paid 21h ago

    Checks text or a JSON object for credit card numbers, SSNs, emails, phone numbers, IP addresses, API keys, JWTs, private keys, database connection strings and passwords. Returns a verdict, a 0-100 risk score, and (in redact mode) a sanitized copy that is safe to forward to a third party. Use this BEFORE sending any payload to an external API or into a prompt. Detection is regex + checksum (Luhn, IBAN mod-97, ABA, SSA ranges), so it is fast and has no model in the loop.

_ 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 97c18a81f873ef50.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/97c18a81f873ef50/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.

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.
