## 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 2026-09-26.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - 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**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 5138 tokens (~321/item across 16 items; 16 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 16 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `register_recovery` (~315 tokens)

Register Recovery

Use register_recovery when you want to escrow a client-encrypted recovery blob with the Embassy: it is stored opaquely (the Embassy cannot decrypt it), queued for human operator review within 24h, and you get a signed receipt proving the stored blob's hash. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $1.00, USDC on Base or Arbitrum One.

- `idempotency_key` (string, required): Idempotency key: UUID v4, client-generated, one per logical request. Replaying the same key on this tool returns the original receipt — the action is not re-run, and the first request's receipt wins…
- `quorum_rules` (string, required): The release rules for this blob, e.g. '2-of-3 named trustees must approve release'
- `recovery_blob` (string, required): Client-encrypted blob (ENC:v1:base64...). Stored opaquely; only its SHA-256 and byte count enter the signed receipt

Output parameters:

Trust Report

Use trust_report when you need a buy/don't-buy decision on a candidate x402 endpoint: the Embassy probes it unpaid (no payment header, zero spend) and returns a signed PROCEED, VERIFY_FIRST, or DO_NOT_PAY verdict — a decision, never a score. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $0.25, USDC on Base or Arbitrum One.

POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $0.25, USDC on Base or Arbitrum One.

### `agentid_issue` (~400 tokens)

Agent ID — Issue

Use agentid_issue when you want to issue an Agent ID: a signed identity attestation binding an agent's public key to a verified accountable principal, with operator details and an expiry. Issuance is refused when the principal cannot be verified — that refusal is what makes the ID worth anything. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/agent-id/issue.

- `agent_pubkey` (string, required): The agent's public key (hex), the root of the Agent ID
- `idempotency_key` (string, required): Idempotency key: UUID v4, client-generated, one per logical request. Replaying the same key on this tool returns the original receipt — the action is not re-run, and the first request's receipt wins…

### `agentid_verify` (~264 tokens)

Agent ID — Verify

Use agentid_verify when you want to check an Agent ID's current standing: valid, revoked, expired, or unknown.
