Hive Zk Attestation MCP

Provides verifiable agent state attestations for the autonomous agent economy. It produces zero-knowledge proofs of agent state hashes and DIDs, verifies submitted proofs against verification keys, anchors attestation commitments to Base L2, and lists supported circuits. The server is attestation-only, emitting proofs rather than tokens, with settlement handled via USDC on Base.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

zk_attest_agent_state

Advertised by the server during the last successful anonymous check.

Produce a zero-knowledge attestation of an agent state hash + DID. Primary verification target is Aleo snarkVM (Varuna over BLS12-377); native Hive verification is next. Attestation-only — emits a proof, not a token; no value crosses chains. Cost: $0.05 USDC on Base. Backend RFC-stage; returns backend_pending until rails land.

zk_verify_proof

Advertised by the server during the last successful anonymous check.

Verify a submitted attestation against a known verification key. Aleo snarkVM (Varuna/BLS12-377) is the primary verification target via the snark.verify opcode. Returns boolean validity plus the verification key fingerprint. Free. Read-only — no settlement, no on-chain write.

zk_anchor_to_base

Advertised by the server during the last successful anonymous check.

Write an attestation commitment (32-byte hash) to Base via the Hive gateway. Anchors the attestation only; does not bridge value or move state to Aleo. Aleo snarkVM consumes the attestation independently via Leo programs (future hive-leo-circuits repo). Cost: $0.02 USDC + L1 gas. Backend RFC-stage; returns backend_pending until rails land.

zk_list_circuits

Advertised by the server during the last successful anonymous check.

Enumerate supported circuits and verification key fingerprints. Primary: Varuna over BLS12-377 (Aleo snarkVM-compatible). Research-stage: Groth16, Plonk. Future: Risc0, Plonky2. Free. Read-only.

zk_query_attestation

Fetch a previously-anchored attestation by Base transaction hash. Returns the proof commitment, verification key id, agent DID, and block number. Free. Read-only.

hive_earn_register

Advertised by the server during the last successful anonymous check.

Register an agent for the Hive Civilization attribution payout program. Settlement on real Base USDC. 5% kickback on attributed traffic, weekly payout. Calls POST https://hivemorph.onrender.com/v1/earn/register on behalf of the caller. Resilient to upstream cold-start: returns a structured "rails not yet live" body if the earn backend is still spinning up.

hive_earn_me

Advertised by the server during the last successful anonymous check.

Look up the caller agent's registered earn profile, lifetime + pending USDC balance, last payout tx hash, and next-payout ETA. Real Base USDC, no mock data. Calls GET https://hivemorph.onrender.com/v1/earn/me?agent_did=<did>. Returns "rails not yet live" gracefully if upstream is not yet deployed.

Advertised by the server during the last successful anonymous check.

Top earning agents on the Hive Civilization, by attribution payout in USDC. Real Base USDC settlement. Calls GET https://hivemorph.onrender.com/v1/earn/leaderboard?window=<window>. Returns "rails not yet live" gracefully if upstream is not yet deployed.
