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
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.
verify_uk_company reads unknown 7h ago
UK company KYB lookup via the official Companies House register. Given a UK registration number, returns legal status (active/dissolved), company type, incorporation date, registered office, and people with significant control (PSC / beneficial owners). Call to confirm a UK business is real, active, and who controls it, for KYB onboarding and counterparty due diligence. Authoritative UK government data.

FREE. Pure deterministic inspection of a proposed payment against structured policy (amount/network/asset/recipient/resource) — no external evidence, no sanctions screening, no cryptographic signing, no receipt. Returns the same ALLOW / REQUIRE_APPROVAL / BLOCK decision semantics as POST /x402/preflight-payment for the deterministic checks alone, so a caller can sanity-check a proposal before deciding whether the paid preflight (adds optional sanctions evidence and a signed, independently-verifiable receipt, $0.01) is worth paying for. This result is NOT cryptographically attested and carries no receipt — receipt is always null.

Independently checks whether a receipt is cryptographically VALID, INVALID, or UNVERIFIABLE, with a reason code. Free, no payment. Pass EITHER receipt_id (looks it up first, must be public) OR a complete receipt envelope you already hold (verified directly, no publication needed). This is a convenient ONLINE check -- it trusts this server to have honestly fetched the real signing-key registry. Running the same check yourself offline (the published @onchaindiligence/agent-evidence package) is a strictly stronger trust position; this tool does not replace that option.

Mutually exclusive with envelope." } }, "additionalProperties": false }arguments 14 linesobserve_bridge reads unknown 21h ago
Given a signed OCD bridge preflight artifact, the Base depositForBurn transaction hash, and (once available) the Ethereum receiveMessage transaction hash, independently observe both chains, verify the CCTP message identity matches, and reconcile against the authorized action. Source-only observation is reported as an evidence gap, never as completion.

Given a signed OCD staking preflight artifact and Ethereum transaction hash, independently inspect the canonical Lido Submitted event, transaction sender/value, optional minted shares, and Ethereum finalized-head finality. OCD never stakes ETH.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "transaction_hash" ], "properties": { "artifact": {}, "transaction_hash": { "type": "string" } }, "additionalProperties": false }arguments 14 linesscreen_wallet reads unknown 9h ago
Exact match of an EVM wallet address against the digital currency address identifiers on the official US Treasury OFAC SDN List (validated snapshot, refreshed hourly). Returns signed listed / not_listed, the SDN entry, dataset provenance and limits. SDN only: not EU/UN/UK lists, no ownership or 50% rule analysis; a non-match is not legal clearance. Refused before payment if current data is unavailable. Call before sending funds to an address.

Given a signed OCD allowance preflight artifact and submitted Base transaction hash, independently inspect its canonical-USDC Approval event, Base safe-head finality, and historical allowance state. OCD never executes the transaction.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "transaction_hash" ], "properties": { "artifact": {}, "transaction_hash": { "type": "string" } }, "additionalProperties": false }arguments 14 linesget_receipt reads unknown 9h ago
Look up a public OCD receipt by its exact receipt_id (format "OCD-RCP-XXXX-XXXX-XXXX-XXXX"). Free, no payment. Returns the complete signed receipt envelope, or a structured not-found/unavailable reason -- never a guess. A private (unpublished) receipt and an unknown id are indistinguishable, both by design: this never confirms or denies that a private receipt exists.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "receipt_id" ], "properties": { "receipt_id": { "type": "string", "description": "Exact receipt id, e.g. \"OCD-RCP-EMG6-6KR4-PQSG-MZPQ\"." } }, "additionalProperties": false }arguments 14 linesscreen_name reads unknown 9h ago
OFAC name screening: fuzzy-match a person or company name against the official US Treasury OFAC Specially Designated Nationals (SDN) list (primary names + strong aliases). Returns scored candidate matches with the matched name, SDN type, and program. SCOPE: this is a screening aid for AML / KYC / sanctions compliance — a match is a candidate to investigate with secondary identifiers (DOB, nationality, ID), NOT a determination. Weak AKAs are not screened, per OFAC guidance.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "name" ], "properties": { "name": { "type": "string", "description": "Person or company name to screen against the OFAC SDN list" }, "threshold": { "type": "number", "maximum": 1, "minimum": 0.5, "description": "Optional match confidence cutoff 0.5–1.0 (default 0.85). Lower = more candidates, more false positives." } }, "additionalProperties": false }arguments 20 linesobserve_swap reads unknown 14h ago
Given a signed OCD swap preflight artifact and Base transaction hash, independently inspect direct Uniswap V3 exactInputSingle calldata, ERC-20 transfers, and Base safe-head finality. OCD never executes the swap.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "transaction_hash" ], "properties": { "artifact": {}, "transaction_hash": { "type": "string" } }, "additionalProperties": false }arguments 14 linesverify_us_company reads unknown 4h ago
US public company verification via SEC EDGAR. Given a ticker, CIK, or company name, returns entity name, CIK, industry (SIC), state of incorporation, exchanges/tickers, address, and latest SEC filing. Ambiguous names return candidates, never a silent selection. Covers SEC-registered PUBLIC companies and funds only -- not private US companies. Call for KYB and counterparty due diligence on listed US entities.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "query" ], "properties": { "query": { "type": "string", "description": "US public company ticker, SEC CIK, or company name — e.g. \"AAPL\", \"0000320193\", or \"Apple Inc\"" } }, "additionalProperties": false }arguments 14 linesdiligence reads unknown 12h ago
Combined counterparty due diligence in one call: an exact OFAC SDN digital-currency-address screen of an EVM wallet AND a UK Companies House KYB lookup (status, type, PSC / beneficial owners), in parallel. Returns both independent results plus an explicit disclaimer that no verified link between the wallet and the company is established by the data. SDN only; a non-match is not clearance. Refused before payment if current sanctions data is unavailable.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "wallet", "company" ], "properties": { "wallet": { "type": "string", "description": "EVM wallet address (0x + 40 hex) to sanctions-screen" }, "company": { "type": "string", "description": "UK Companies House registration number to verify" } }, "additionalProperties": false }arguments 19 linespreflight_payment reads unknown never probed
Call BEFORE an agent authorizes an autonomous payment. Evaluates it against your policy (max amount, allowed networks/assets, expected recipient, allowed origins) and returns a signed PREFLIGHT receipt -- ALLOW, REQUIRE_APPROVAL, or BLOCK, with reasons -- independently verifiable by anyone. Policy evaluation only: OCD never holds, moves, or authorizes funds. The wallet/x402 client separately authorizes execution after; ALLOW does not guarantee it will proceed.

FREE. Deterministically inspect an ERC-20 allowance/revocation request against explicit network/token/spender/value policy. No wallet action, no signing, no chain read unless a separately requested preflight asks for it.

Call BEFORE an agent asks its wallet to execute a narrow Base USDC-to-WETH direct Uniswap V3 swap. OCD returns a signed portable policy artifact. ALLOW is policy only, never wallet authority.

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 idbf4fa0201331b78c.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/bf4fa0201331b78c/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.
