## 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**: 59/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1625 tokens (~325/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - 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**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; 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 60, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-02 (score 59, 0)

- [security] The server rewrote its instructions, which are the text every model session reads
- [functional] Server version: 2.3.1 → 2.4.0

### 2026-08-01 (score 59, +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.

### 2026-07-31 (score 58, +2)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-07-30 (score 56)

First indexed and scored.

## MCP tools (5)

### `quantdata_request_free_api_key` (~161 tokens)

Request a free Quant Data API key

Send a free qd_ API key to an email address. No account, card, payment or GUI is required. The key covers all four market-data tools, sharing 10 successful calls per UTC day. The raw key is delivered only to the inbox and is never returned in this tool result. Ask the user for the email address before calling. Set marketing_opt_in to true only when the email owner explicitly asks to receive occasional product updates; it defaults to false and is not required for the key. A true value stays pending until the recipient replies SUBSCRIBE to the key email.

Input parameters:

- `email` (string, required): Inbox that should receive the qd_ key.
- `marketing_opt_in` (boolean): Optional separate consent for product-update emails.

### `quantdata_day_type` (~303 tokens)

Day-type probabilities

Day-type probabilities for the trading session in progress: a calibrated distribution over five classes (trending up, trending down, range, trending range, reversal) from a model trained on S&P 500 futures 5-minute bars. Answers 'what kind of day is this so far'. Descriptive statistics about how comparable past sessions resolved — not a forecast of today and not a recommendation. Check session_is_live before calling the read 'today', and check bars: fewer than 18 (90 minutes) means the distribution is provisional.

Input parameters:

- `session` (string): Omit for the US day session, the only window these numbers were measured on. 'asia' (09:00-16:00 Beijing) is accepted for 24-hour instruments only and is explicitly unvalidated — the pre-registered t…
- `symbol` (string, required): Ticker. US stocks and ETFs as-is (NVDA, SPY). US futures with =F (ES=F, GC=F). Hong Kong as digits.HK (3690.HK). China A-shares as 6 digits (600519). Crypto as PAIR-USD (BTC-USD). Spot FX with no sla…

### `quantdata_weis_wave` (~344 tokens)

Volume-price wave structure

Weis Wave volume-price structure: price grouped into waves with volume summed per wave, plus which of five classical volume-price events have fired. Each event carries the win rate measured for it on sixteen years of S&P 500 futures data, including the two that came out REVERSED against the tradition. Answers 'is there volume behind this move'. Quote the measured reference numbers rather than the folklore. Needs real exchange volume: spot FX has none — use CME currency futures (6E=F) instead. Use session='full' to match the published reference-rate window, or the default 'rth' for a regular-session-only read.

Input parameters:

- `session` (string): Omit for the US regular session. Use 'full' when comparing returned Weis events with the published reference win rates: those rates were measured on the whole bar stream, including pre/post-market. '…
- `symbol` (string, required): Ticker. US stocks and ETFs as-is (NVDA, SPY). US futures with =F (ES=F, GC=F). Hong Kong as digits.HK (3690.HK). China A-shares as 6 digits (600519). Crypto as PAIR-USD (BTC-USD). Spot FX with no sla…

### `quantdata_max_pain` (~223 tokens)

Options max pain by expiration

Options max pain per expiration, computed from open interest alone: the strike at which option buyers lose the most in aggregate if the underlying settled there. Pure arithmetic — no pricing model, no volatility assumption, so anyone with the same chain gets the same number. Also returns put/call ratio and the heaviest call and put open-interest strikes. Returns every expiration inside 45 days rather than picking one, because the figure is per-expiration and the near- and far-dated values routinely disagree. US listed stocks and ETFs only: cash-settled index options (SPX, NDX, RUT, VIX) return an error — use SPY, QQQ, IWM. Open interest settles overnight, so this describes the prior session's positioning; report as_of and spot_date alongside the number.

Input parameters:

- `distribution` (boolean): Include the full open-interest distribution by strike. Large; only request it when the user wants strike detail.
- `symbol` (string, required): US listed stock or ETF ticker, e.g. NVDA or SPY.

### `quantdata_gamma` (~257 tokens)

Estimated dealer gamma exposure

Estimated dealer gamma exposure (GEX) for a US listed stock or ETF: net and gross GEX, the zero gamma (flip) level and the heaviest strikes. Unlike max pain this is a Black-Scholes ESTIMATE — zero rate, zero dividend, implied volatility solved from end-of-day quotes, and the convention that dealers are long every call and short every put. Keep that framing when reporting it. A null flip is not an error: check flip_status — 'no_sign_change_within_10pct' means net gamma keeps one sign across the whole traded range, which is a state worth reporting. US listed stocks and ETFs only, with a liquid chain: cash-settled index options (SPX, NDX, RUT, VIX) return an error — use SPY, QQQ, IWM instead. Reads the prior session's settled open interest and cannot update intraday whatever the clock says, so report as_of and spot_date with the number.

Input parameters:

- `by_strike` (boolean): Include the strike-level gamma profile. Large; only request it when the user wants strike detail.
- `symbol` (string, required): US listed stock or ETF ticker, e.g. NVDA or SPY.
