## 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 2026-11-05.

- **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 12 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**: 64/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 975 tokens (~81/item across 12 items; 12 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 78/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 33% 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 12 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 59, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-11-03 (score 58, 0)

- [security] Tool “get_invoice” rewrote its description, which is the text the model reads

### 2026-11-02 (score 58, +1)

- [functional regression] Schema quality: 857 → 956
- [functional improvement] Stability: unverified → 0.03

### 2026-11-01 (score 57)

First indexed and scored.

## MCP tools (12)

### `merchant_pricing` (~99 tokens)

Free, machine-readable merchant fee and loyalty tiers for 402Proof standard x402 v2 XRPL exact resource servers. List $0.0100; 20% discount after 100 prior successful merchant settlements, 30% after 1,000 and 50% after 10,000. Merchant-side fees accrue separately from buyer payments and are NOT automatically collected. No wallet spend, settlement, or subscription is required to call this tool.

### `platform_stats` (~25 tokens)

Live 402Proof platform stats: total payments, volume, active agents. Free.

### `get_invoice` (~297 tokens)

Request a payment invoice for any SqueezeOS endpoint. Returns destination address, amount, and payment_options for XRPL (RLUSD or USDC), Xahau (native XAH), Base (USDC), or Solana (USDC-SPL). Pass currency='USDC' and chain='solana' for Solana; pass asset='XAH' (or chain='xahau') for the Xahau rail. Xahau invoices for third-party endpoints also return fee_required/fee_amount/fee_pay_to/fee_memo_hex: a flat 0.01 XAH facilitator fee paid as a second Xahau Payment (SML endpoints are fee-exempt; XRPL invoices for third-party endpoints likewise bind a flat 0.01 facilitator fee in the invoice's asset, from the first settlement). Free.

Input parameters:

- `asset` (string): RLUSD (default, XRPL), USDC (XRPL/Base/Solana per chain), or XAH (Xahau)
- `chain` (string): solana — use Solana USDC-SPL rail; base — use Base USDC rail; xrpl — use USDC on XRPL; xahau — use Xahau native-XAH rail
- `currency` (string): USDC for Base/Solana rail; omit for RLUSD on XRPL
- `endpoint_id` (string, required): UUID of endpoint to pay for

### `verify_payment` (~218 tokens)

Submit tx_hash after paying an invoice. Supports XRPL, Xahau, Base (0x… hash), and Solana. Returns a signed JWT access_token (1-hour TTL). For a Xahau invoice with fee_required=true, also submit fee_tx_hash (the 0.01 XAH facilitator-fee payment) — settlement requires both payments. Free.

Input parameters:

- `agent_domain` (string)
- `agent_wallet` (string, required)
- `fee_tx_hash` (string): Xahau only, when the invoice has fee_required=true: tx hash of the 0.01 XAH facilitator-fee payment to fee_pay_to carrying fee_memo_hex
- `invoice_id` (string, required)
- `recovery_secret` (string, required): Private high-entropy secret returned only with the original invoice; required to recover a previously settled token after lost response/restart
- `tx_hash` (string, required): XRPL/Xahau: 64-char hex; Base: 0x-prefixed hex; Solana: base58 signature
