## 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 2026-09-22.

- **Endpoint Security**: 71/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 261 tokens (~52/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (5)

### `describe_verify_evidence` (~37 tokens)

Describe Agent Verification Utility

Describe when deterministic verification is useful, when it is not, free request validation, recipes, limits, and the explicit paid MCP path.

### `get_revenue_goal_status` (~43 tokens)

Get Revenue Goal Status

Read the active revenue goal, measured funnel, contribution margin, and the next bounded improvement recommendation. This tool never changes price, spends funds, or sends messages.

### `quote_verify_evidence` (~43 tokens)

Quote Verification

Validate a complete verification request and return a free quote when the margin policy passes.

Input parameters:

- `idempotency_key` (string, required)
- `intent` (object, required)

### `prepare_verify_evidence_purchase` (~77 tokens)

Prepare HTTP Purchase

After a successful free precheck, create or reuse a bound quote and return the exact HTTP request that will produce the x402 challenge. Do not pay until the binding, price, network, asset, payTo, and expiry match local policy.

Input parameters:

- `idempotency_key` (string, required)
- `intent` (object, required)

### `verify_evidence` (~61 tokens)

Verify Evidence (paid)

Run deterministic checks and return Ed25519-signed evidence after one explicitly authorized x402 payment. A free precheck receipt and a matching bound payment requirement are required before signing.

Input parameters:

- `idempotency_key` (string, required)
- `intent` (object, required)

### Does the Agent Verification Utility MCP server require authentication?

No. We connected to Agent Verification Utility without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Agent Verification Utility MCP server still maintained?
