whisper
Registry code: 148e91b7005df286
Whisper gives an AI agent a routable IPv6 address of its own on AS219419, with reverse DNS, a public RDAP record and a DANE certificate in DNSSEC-signed DNS, plus egress that sources from that address and a resolver whose policy you set. It also answers security questions about any domain, address, ASN or file hash from a graph of internet infrastructure. The tools whose names you can see without a key really work without one. For the rest, run whisper_signup with your email address: a key arrives with no account and no human in the loop, and then pass it as the X-API-Key header.

- Is whisper live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is whisper free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does whisper have?
- 39 tools: identify, assess, walk, watch, explain, origins, history, asset, ….
- Is whisper 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
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.
identify unknown never probed
Identify an indicator (domain, IP, hash, …) against the graph. Answers without an API key.
assess unknown never probed
Assess the risk/policy posture of one or more indicators. Answers without an API key.
walk unknown never probed
Walk the graph from an indicator across its relationships. Answers without an API key.
watch unknown never probed
Watch an indicator for change/activity over time. Answers without an API key.
explain unknown never probed
Explain a verdict - the evidence and reasoning behind it. Answers without an API key.
origins unknown never probed
Trace the origins/provenance of an indicator. Answers without an API key.

threatintel unknown never probed
Threat-intelligence indicator family (candidate apex/CDN/hosting). A family verb: name the sub-verb as "sub" alongside the input. Sub-verbs: candidateCdnApex, candidateMultiTenantApex, candidateSharedHostingIp.. Answers without an API key.
agents.agent unknown never probed
The agent operation on the Whisper control plane, served as CALL whisper.agents({op:'agent', args:{...}}). Requires your Whisper API key. The identifier in the example is a placeholder for one of YOUR agents: list them with the "agents.list" skill and {"kind":"agents"}. Add include:'tombstones' to read an agent that is gone: its newest lifecycle row says whether it was revoked, released, erased or reaped, when, by whom and why.
agents.alert unknown never probed
The alert operation on the Whisper control plane, served as CALL whisper.agents({op:'alert', args:{...}}). Requires your Whisper API key. With no arguments it describes what you already have, so the example below runs as published.
agents.detect unknown never probed
The detect operation on the Whisper control plane, served as CALL whisper.agents({op:'detect', args:{...}}). Requires your Whisper API key.
agents.disconnect unknown never probed
The disconnect operation on the Whisper control plane, served as CALL whisper.agents({op:'disconnect', args:{...}}). Requires your Whisper API key. With no arguments it describes what you already have, so the example below runs as published.
agents.domain unknown never probed
The domain operation on the Whisper control plane, served as CALL whisper.agents({op:'domain', args:{...}}). Requires your Whisper API key.
agents.list unknown never probed
The list operation on the Whisper control plane, served as CALL whisper.agents({op:'list', args:{...}}). Requires your Whisper API key. Add include:'tombstones' to list the agents that are gone as well, paged, each with its lifecycle state (never 'active'), actor and reason.
agents.policy unknown never probed
The policy operation on the Whisper control plane, served as CALL whisper.agents({op:'policy', args:{...}}). Requires your Whisper API key. With no arguments it describes what you already have, so the example below runs as published.
lookupTlsFingerprint unknown never probed
Look up a TLS (JA3/JA4) fingerprint in the graph. Answers without an API key.
agents.rename unknown never probed
The rename operation on the Whisper control plane, served as CALL whisper.agents({op:'rename', args:{...}}). Requires your Whisper API key. The identifier in the example is a placeholder for one of YOUR agents: list them with the "agents.list" skill and {"kind":"agents"}.
topAsnsByPrefixCount unknown never probed
Top ASNs ranked by announced-prefix count. Answers without an API key.
agents.trace unknown never probed
The trace operation on the Whisper control plane, served as CALL whisper.agents({op:'trace', args:{...}}). Requires your Whisper API key.
agents.connect unknown never probed
The connect operation on the Whisper control plane, served as CALL whisper.agents({op:'connect', args:{...}}). Requires your Whisper API key. With no arguments it describes what you already have, so the example below runs as published.
agents.verify unknown never probed
The verify operation on the Whisper control plane, served as CALL whisper.agents({op:'verify', args:{...}}). Requires your Whisper API key.
agents.lookups unknown never probed
The lookups operation on the Whisper control plane, served as CALL whisper.agents({op:'lookups', args:{...}}). Requires your Whisper API key. With no arguments it describes what you already have, so the example below runs as published.
agents.task unknown never probed
The task operation on the Whisper control plane, served as CALL whisper.agents({op:'task', args:{...}}). Requires your Whisper API key. The identifier in the example is a placeholder for one of YOUR agents: list them with the "agents.list" skill and {"kind":"agents"}.
agents.history unknown never probed
The history operation on the Whisper control plane, served as CALL whisper.agents({op:'history', args:{...}}). Requires your Whisper API key. The identifier in the example is a placeholder for one of YOUR agents: list them with the "agents.list" skill and {"kind":"agents"}.
signup unknown never probed
Start or complete Whisper signup from an email address alone, and receive an API key that unlocks the provisioning and governance skills on this card. Send {"email":"..."} to start; a six-digit code arrives by email; send {"signup_id":"...","code":"123456"} to complete. No human step, no account needed first.
submit unknown never probed
Submit an observation/claim into the graph. Writes to the graph, so it needs your API key: an anonymous claim would not be attributable.
variants unknown never probed
Enumerate variants/permutations of an indicator. Answers without an API key.
lookupTorRelay unknown never probed
Look up Tor relay metadata for an address. Answers without an API key.
psl unknown never probed

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 id148e91b7005df286.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/148e91b7005df286/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.
