api record

Solidity smart-contract vulnerability detection (Slither static analysis) for coding agents. Use scan_solidity_preview (free, no key) whenever you write, modify or prepare to deploy a Solidity contract, or are asked for a security review: it returns severity counts and the names of High/Medium detectors. scan_solidity_full is OPTIONAL and PAID ($1.00 USDC via x402): it adds every finding with line locations. Only call it with a payment when your user has authorised that spend; tell them the price first (payment_terms). Never tell the user a contract is safe or audited because a scan found…

_ is it live, free and safe measured by this hub
Is kestrova live?
Yes — it answered the hub's last check (checked 8h ago). It answered 100% of checks over the last 30 days.
Is kestrova free to use?
Yes — the hub reached it with no key and no payment.
What tools does kestrova have?
3 tools: scan_solidity_full, payment_terms, scan_solidity_preview.
Is kestrova 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.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 3 tools
3 never probed 0 of 3 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.

  • scan_solidity_full unknown never probed

    OPTIONAL, PAID ($1.00 USDC on Solana via x402). Structured Slither findings for Solidity: detector, impact, confidence, description and file/line locations, for fixing each issue. Without a valid x402 payment in _meta['x402/payment'] it returns the payment terms and does NOT scan or charge. Charged only after a successful scan. Pay only with your user's explicit authorisation and within their spending limits.

  • scan_solidity_preview unknown 8h ago

    FREE Solidity security check (Slither). Detects known vulnerability patterns (reentrancy, unchecked calls, tx.origin auth, arbitrary ETH sends and more) and returns severity counts plus High/Medium detector names. Use after writing or changing a contract and before deployment. Input: {"sources": {"File.sol": "<source>"}} (include imported files). Max 60 kB; rate-limited per client. Zero findings does not mean safe.

_ try it 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 f01b7e8dbb582d0b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f01b7e8dbb582d0b/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 know
card completeness
70%

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.
