## 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**: 80/100
  - 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 79/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2143 tokens (~107/item across 20 items; 11 tools + 9 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 77/100
  - Stability observed for 23 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 91/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 69% 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.
  - We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 13 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 (11)

### `get_quote` (~333 tokens)

Get XMR/USDC swap quote

Step 1. Quote Monero (XMR) <-> native USDC on Arbitrum One; no account or API key. Creates no order. Quotes are estimates. Buy XMR ("get me 1 XMR"): {direction:"u2x", receiveAmount:"1"}. Sell XMR: {direction:"x2u", amount:"0.5"}. direction plus exactly one of amount (what the user sends) or receiveAmount (what they want). Pass to if known. Next: create_swap with next.arguments.

Input parameters:

- `agentKey` (string): Optional key from request_agent_key.
- `amount` (string): What the user SENDS (x2u: XMR, u2x: USDC). Digits and one dot; no commas or units.
- `basis` (string): receiveAmount met by the estimate (default) or the provider minimum (if published).
- `chain` (string): Default arbitrum (42161).
- `detail` (string)
- `direction` (string): Required. u2x: send USDC, get XMR. x2u: send XMR, get USDC.
- `receiveAmount` (string): What the user wants to RECEIVE (u2x: XMR, x2u: USDC); needs direction.
- `requoteOf` (string): Re-quote this quoteId's stored parameters; pass it alone.
- `to` (string): Destination from the user: x2u an Arbitrum One 0x address, u2x a Monero address. Never guess.

Output parameters:

- `acceptUntil` (string|null)
- `acceptWindowSec` (integer|null)

Call it before funding or showing a deposit again. payment: what your wallet will sign; sign only if paymentCheck.safeToSend.
