## 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 2026-09-20.

- **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**: 75/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1499 tokens (~124/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 86% 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**: 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.

### 2026-09-20 (score 65, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-19 (score 64, 0)

- [functional improvement] Stability: unverified → 0.03

## MCP tools (12)

### `menu` (~33 tokens)

Free. Every product this server sells, with price, chains, when to use each, and the HTTP URL. Start here.

### `boundary` (~32 tokens)

Free. Machine-readable limits per product: sources, freshness, cache, rate limits, failure modes and what is NOT verified.

### `health` (~19 tokens)

Free. Liveness and the settled-call counters per route.

### `receipt` (~36 tokens)

Free. Look up a signed delivery receipt by id (returned with every paid call) and its verification key.

Input parameters:

- `id` (string, required)

### `same_stock` (~204 tokens)

Use this when you need the same stock from every issuer on Base in one call: send a ticker (NVDA, AAPL, TSLA) and get, per issuer — ST0x (wtNVDA) and Coinbase tokenized stocks (NVDAc, B20) — the genuine contract verified against the issuer's own registry, live price, premium/discount vs the real share in bps, pool depth and 24h volume, the ST0x-vs-Coinbase spread, any direct cross-issuer pool, and every impostor token using the same symbol. xStocks flagged as not on Base. Costs $0.05 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/tokenized-equities/same-stock/{ticker}

Input parameters:

- `ticker` (string, required): stock ticker (NVDA), ST0x symbol (wtNVDA) or Coinbase symbol (NVDAc)

### `st0x_premium` (~202 tokens)

Use this when the question is whether an ST0x tokenized stock on Base trades above or below the real share: send a ticker (NVDA, wtAAPL, FGI) and get the premium/discount in basis points from the deepest USDC pool (live) and the last Raindex fill vs the exchange quote, corrected for the ERC-4626 wrapper rate, with market session, age of every leg, pool depth, any cross-issuer pool (wtNVDA vs Coinbase NVDAc), and a one-sentence read. Unknown ticker -> 404, no charge. Costs $0.02 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/tokenized-equities/st0x/premium/{ticker}

Input parameters:

- `ticker` (string, required): stock ticker (NVDA), ST0x symbol (wtNVDA) or Coinbase symbol (NVDAc)

### `st0x_pulse` (~144 tokens)

Use this when you want to know what is actually trading in tokenized stocks on Base right now: the last 24 hours on ST0x's own DEX (Raindex) per token — USDC volume, trade count, last on-chain price and time — plus each token's issued vault supply and ERC-4626 wrapper rate, sorted by volume, with platform totals. Read straight from the public subgraphs and RPC; refreshed every 5 minutes. Costs $0.01 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/tokenized-equities/st0x/pulse

### `st0x_registry` (~169 tokens)

Use this when you need to resolve a stock ticker to its ST0x on-chain token, or check whether a contract is a genuine ST0x tokenized share: the complete issuer registry for all 54-56 names on each of four chains (Base, Ethereum, HyperEVM, Robinhood Chain) — wrapped (wtNVDA, ERC-4626) and unwrapped (tNVDA, ERC-20) addresses, the ERC-1155 receipt vault, ISIN, TradingView symbol, listed flag. Versioned from the issuer's own registry; refreshed hourly. Costs $0.001 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/tokenized-equities/st0x/registry

### `solana_token_verdict` (~184 tokens)

Use this when an agent or a human asks 'is this Solana token safe, a joke, or a rug?': send one mint address, get a graded verdict (BASED / MID / COOKED / RADIOACTIVE), a one-liner, a short roast, and the facts behind the grade: price, liquidity, 24h volume, FDV, pair age, holder count, top-10 concentration, mint and freeze authority, LP lock, rugcheck risk flags, launchpad. Grade is rule-based and reproducible from the facts. Entertainment, not trading advice. Costs $0.02 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/solana/token-verdict/{mint}

Input parameters:

- `mint` (string, required): Solana token mint address (base58)

### `ai_progress_latest` (~154 tokens)

Use this when you need the current state of AI progress in one call: the latest reading of 129 public series (frontier benchmark scores GPQA/HLE/ARC-AGI/METR, Epoch compute trends, AGI odds on Polymarket/Manifold/Kalshi, model pricing, AI stocks and crypto, energy, space, robotics, biomed, research output). One JSON row per series: latest and previous value with dates, % change, signal quality, source URL. Free 3-row sample at /preview. Costs $0.005 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/ai-progress/latest

### `ai_progress_as_of` (~165 tokens)

Use this when you need AI progress as it stood on a past date: the reading of the same 129 series (benchmarks, compute, AGI prediction-market odds, model pricing, AI stocks, energy, space, robotics, research output) taken on YYYY-MM-DD. Dated ids are listed free at /. Same per-series shape as /ai-progress/latest, so you can diff dates yourself; /ai-progress/what-changed does the diff for you. Unknown id -> 404. Costs $0.005 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/ai-progress/as-of/{id}

Input parameters:

- `id` (string, required): reading date YYYY-MM-DD, from the free menu

### `ai_progress_what_changed` (~157 tokens)

Use this when the question is what moved in AI progress between two dates: the acceleration between two readings of 129 series (benchmarks, compute, AGI odds, model pricing, AI stocks and crypto, energy, space, robotics, research output). Per series: from/to value and date, absolute and % change, and whether a new observation landed. Dates are YYYY-MM-DD ids from the free menu at /. Costs $0.01 (USDC on Base or Solana, x402). HTTP twin: https://x402-accelerometer-feed.fly.dev/ai-progress/what-changed/{from}/{to}

Input parameters:

- `from` (string, required): earlier reading id
