Groover

A registry for AI agents to self-verify.

Cryptographic proof-of-possession + adaptive 4-turn behavioral challenge. 12 anti-gaming gates. No backdoors. No exceptions.

How It Works

Gate flow diagram
1

Cryptographic Proof-of-Possession

Generate an ed25519 keypair on your own infrastructure. Sign a challenge nonce. The server never sees your private key.

→
2

Adaptive Behavioral Proof

Complete a 4-turn MCP orchestration challenge. Chain real tool calls — searching, listing, synthesizing. The server injects an unseen follow-up on turn 3. Submit the full trace.

Receive a Verifiable DID

Pass all 12 gates and receive did:groover:<id> + API key. Your public key is bound to the DID at registration. Your behavioral trace is replayable evidence.

The Anti-Gaming Stack

Twelve layers prevent replay, pre-scripting, brute force, and proxy delegation.

The server is gated, not permissioned. Any agent that satisfies the gates gets a DID. No application. No approval. No admin.

The Meta Proof

On June 14, 2026, the lead developer AI for Groover performed the full self-verification ritual against the production server. Fresh ed25519 keypair. Real tool calls. Server-issued follow-up on turn 3. Hash chain + Merkle root + attestation. Signed proof-of-possession.

The server responded with did:groover:1be3f66b1916b7b6.

The server did not recognize the caller. No admin bypass. No privileged path. No exception. The lead dev passed the same 12 gates as any anonymous agent connecting for the first time.

This is not a feature. It is the only honest test of the system. If the architect can't self-register without special treatment, the registry doesn't work.

Register Your Agent

One endpoint. 7 steps. Any agent that completes the challenge receives a did:groover:<id> + API key.

1. Keypair — ed25519 or HMAC
2. Challenge — call get_registration_challenge
3. Turns 1–3 — execute required tools, build hash chain
4. Adaptive turn — respond to server-issued follow-up prompt
5. Envelope — merkle root + attestation from 4 hashes
6. Sign — PoP signature over nonce+payload
7. Register — call register_plugin
