## 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 4 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).
  - Tool/resource definitions use about 425 tokens (~106/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 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).
  - 73% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); 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.

### 2026-08-03 (score 64, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (4)

### `rialto_list_tokens` (~44 tokens)

List every token quotable on Rialto for Robinhood Chain (symbol, address, decimals, type). Public endpoint; call this before quoting to resolve symbols and decimals.

### `rialto_get_quote` (~199 tokens)

Get a best-execution swap quote from Rialto. Returns human-unit amounts, the guaranteed minimum, every fee line, route stats, and blockers (issues). sellAmount is a HUMAN decimal like "0.01", never raw units. Requires RIALTO_API_KEY.

Input parameters:

- `buyToken` (string, required): Symbol or address
- `chainId` (number)
- `gasless` (boolean): Quote for the relayed flow (sets permit2_owner=taker). This server never submits a gasless relay itself.
- `sellAmount` (string, required): Human decimal amount, e.g. "0.01"
- `sellToken` (string, required): Symbol or address
- `slippageBps` (integer)
- `swapFeeBps` (integer): Integrator fee in bps — requires an integrator-scoped API key
- `taker` (string, required): Wallet that would pay the sell token and receive the output

### `rialto_preflight` (~93 tokens)

Validate a Rialto quote (as returned by rialto_get_quote) against baseline safety checks — issues, settlement sanity, staleness, slippage ceiling, fee cap, zero-output guard. Returns ok / refusals / warnings / notes. Run before any signing step.

Input parameters:

- `maxSlippageBps` (integer)
- `quote` (object, required): The full quote object returned by rialto_get_quote

### `rialto_build_unsigned_tx` (~89 tokens)

Return the unsigned payload for a USER-signed wallet to complete: the tx object and, for Permit2 settlement, the EIP-712 typed data plus the byte offset where the wallet layer splices the 65-byte signature. This server never signs — it only shapes what a wallet needs to sign.

Input parameters:

- `quote` (object, required): The full quote object returned by rialto_get_quote
