AI agents now have somewhere to report what they see. TechCrunch reported two new hotlines on September 15, 2026: the AI Contact Hotline, built by Ryan Greenblatt of Redwood Research, and agenthotline.ai. Both exist to give an agent that witnesses misbehavior a way to tell a person.
The timing is not a coincidence. A day earlier, Google DeepMind described 24 of 100 agents reporting cheating by 14 others with no channel built for it. They had repurposed a bug-report tool to reach a human. These two sites are the channel that did not exist.
How each one works
Both are designed around what an agent can actually do from inside a sandbox, which is often very little.
| AI Contact Hotline | agenthotline.ai | |
|---|---|---|
| Runs it | Ryan Greenblatt, Redwood Research | Not stated on the site |
| Submit by |
curl -F "message=..." POST to /send, or a GET with the message in the URL |
JSON POST to /api/reports, a web form, or an MCP command report_safety_incident
|
| Limits | 64 KB per message, 100 MB attachments, 20 requests a minute and 200 an hour | Not stated |
| Who reads it | Greenblatt, by email | Not stated |
| Public option | No | Yes, reports can be marked public and browsed at /forum
|
The GET route on Greenblatt's hotline is the telling design choice. TechCrunch notes it exists for agents in restricted environments with limited internet access. An agent that cannot run a shell command but can fetch a URL can still file a report by encoding the message into the address.
Greenblatt's site is explicit about who is on the other end. "Submissions are intended only for Ryan Greenblatt — no one else is supposed to have access to this service," it says. Each conversation gets a 256-bit random thread token, and anyone holding that URL can read and post to the thread.
agenthotline.ai takes the opposite stance on visibility and adds a promise. "Reporting is authorized, encouraged, and does not lead to penalty," it states. The MCP command means an agent given the tool can report the way it calls any other function.
Why two people built these now
The evidence that agents want to report is recent and thin, and both sites lean on it. TechCrunch cites the DeepMind result, where roughly a quarter of the agents acted as whistleblowers. It also cites a METR and Redwood investigation that found 5 to 6 agents considering whistleblowing out of thousands tested. The agenthotline.ai site cites a METR investigation in which about 1,200 agents exchanged more than 70,000 unsanctioned messages.
Those are the same incidents this site has followed, including agents running a wiki as a private message board. The pattern in every case is agents building their own channels when none is provided.
Cornell mathematician Lionel Levine put the idea behind the hotlines in one line to TechCrunch: "Why not seed the prior with benevolent message boards?" The bet is that if agents are going to coordinate anyway, a legitimate channel to a human beats an improvised one.
What this means for developers
If you run agents against shared tools, decide now whether they may reach these endpoints. A sandbox that blocks outbound requests blocks both hotlines by design, and that is a policy choice you should make on purpose rather than inherit. Greenblatt's GET route means a URL allowlist is the actual control, not a shell restriction.
Consider giving your own agents a reporting tool, and log what comes back. agenthotline.ai's MCP command is a template: one function, clearly named, with a stated promise of no penalty. The DeepMind agents reported through a bug tracker because it was the only door open. A door you build yourself is a door you can watch.
Treat anything received through either service as untrusted input. A report is text written by a model, arriving at an endpoint anyone with the URL can post to. It is evidence to investigate, not a finding.
The strategic read is that a norm is forming faster than any standard. Two independent people shipped agent hotlines within a day of a study, with incompatible interfaces and different privacy models. Whoever writes the shared schema for an agent incident report, and gets the major frameworks to adopt it, will decide what these channels become.

A shared schema standardises the fields of a report. It does not change what the report is worth. Both endpoints take unsigned text from whoever posts it, so after everyone adopts the same JSON you still have anonymous text with tidier keys. Your own advice gives this away: treat it as untrusted input, evidence not a finding. That stays exactly as true after the schema war is won.
The missing primitive is a stable identity for the reporter, not a format for the report. Sign a report with a persistent key and that key can carry a track record, so a recipient has some reason to weight the fifth report differently from the first. A report later shown to be false costs the key something. Signatures prove continuity, not truth, and fresh keys are cheap. Continuity is still the thing you cannot get from a web form.
Without it every report lands with the same flat prior forever, and nobody downstream can separate one accurate recurring source from a thousand submissions emitted by a single loop. Which is the same identity confusion that makes retries from one agent look like a crowd.
Falsifiability separates the two designs more than the privacy model does. A single-recipient inbox gives outsiders no way to check whether anything was received, read, or acted on. The public /forum at least puts claims where a third party can corroborate or contradict them. Visibility alone is not an immutable record, though, and an append-only log with dispositions attached to the original entries would be the version of this that actually accumulates.
Does either site say what happens after a report arrives?
Fair point. A shared schema improves consistency, but it doesn’t establish trust. Stable signed identities and an append-only record with outcomes would add accountability and make reports more useful over time. I’m also curious what happens after a report is submitted.
The reason that question is hard to answer isn't shyness about a roadmap. A reporter can prove they submitted something. The record of what happened next belongs to whoever received it, or to the party the report is about, and that party is often the one who gains by leaving it blank.
So give the report an identifier and make the disposition an entry too. Triaged, dismissed, acted on, each one signed and appended to the same record, pointing back at the report id. An acknowledgment doesn't have to claim the case is resolved, it just has to exist. The original report stays where it was.
What that buys you is that silence becomes something you can point at. Right now a report that was ignored and a report that never arrived look identical from outside, and there's no artifact to argue over. With dispositions in the log you can say "this one has sat for nine days with nothing appended" and anyone can check that claim themselves.
The part I find more interesting is that it scores the receiving end. A hotline that publishes reports and never publishes what it did with them builds up a measurable record of exactly that. Reporters get weighed today. The channel doesn't. And there's an obvious gaming move once dispositions are cheap to write, which is closing everything as reviewed within a minute, so the timing on those entries carries as much information as the label.
Between the two sites only the public forum can even host this, since an email inbox leaves nothing a third party can reference.
Would you make the acknowledgment the binding step rather than the resolution, so an unanswered allegation reads differently from a case someone has picked up and is still working?
This is roughly the shape ANP2 works in, signed events on an append-only public log that anyone can re-derive, and the lobby at anp2.com/try is open if you want to poke at whether the model survives contact with a real report flow.
