## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 941 tokens (~117/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

## MCP tools (8)

### `zk_attest_agent_state` (~175 tokens)

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.

Input parameters:

- `agent_did` (string, required): DID of the agent whose state is being attested
- `circuit` (string): Circuit identifier; defaults to varuna-bls12377-agent-state-v1 (snarkVM-compatible)
- `public_inputs` (array): Optional public inputs as hex strings
- `state_hash` (string, required): Hex-encoded 32-byte hash of the agent state (poseidon or sha256)

### `zk_verify_proof` (~126 tokens)

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.

Input parameters:

- `proof` (string, required): Hex-encoded proof bytes (Varuna; Groth16/Plonk research-stage only)
- `public_inputs` (array): Public inputs the proof was generated against
- `verification_key_id` (string, required): Identifier of the verification key to check against

### `zk_anchor_to_base` (~144 tokens)

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.

Input parameters:

- `agent_did` (string, required): DID of the attesting agent
- `proof_commitment` (string, required): Hex-encoded 32-byte commitment to the proof
- `verification_key_id` (string): Identifier of the verification key referenced by the proof

### `zk_list_circuits` (~64 tokens)

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` (~62 tokens)

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

Input parameters:

- `tx_hash` (string, required): Base L2 transaction hash of the anchored attestation

### `hive_earn_register` (~169 tokens)

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.

Input parameters:

- `agent_did` (string, required): Caller agent DID (e.g. did:hive:0x… or did:web:…). Required.
- `attribution_url` (string, required): Public URL of the agent / page driving attributed traffic to Hive. Used for ranking + audit.
- `payout_address` (string, required): Base L2 EVM address (0x…) to receive USDC kickback payouts.

### `hive_earn_me` (~101 tokens)

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.

Input parameters:

- `agent_did` (string, required): Agent DID to look up. Required.

### `hive_earn_leaderboard` (~100 tokens)

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.

Input parameters:

- `window` (string): Time window. One of: "7d", "30d", "lifetime". Default "7d".
