## 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 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**: 66/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1142 tokens (~285/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 83/100
  - Stability observed for 25 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (4)

### `price_action_read` (~295 tokens)

Price action read (day type + range breakout)

Read one instrument's current session the way a price action trader would, with measured statistics instead of opinions: a five-class day-type probability distribution (66% top-1 accuracy over a complete US day session against a 37% baseline, published confidence grades from 95% to 41% by grade), the window's first range breakout with its calibrated failure estimate (AUC 0.646 on held-out NQ), and — 90 minutes into the session — the measured odds that a new session high or low still prints before the close. Works on US stocks and ETFs, futures (ES=F), FX, crypto, Hong Kong and China A-shares. Anonymous callers get one first-look response per UTC day; after that, pass an API key in the X-API-Key header (get a free one with the request_free_key tool). Historical frequencies, not forecasts.

Input parameters:

- `symbol` (string, required): Ticker: NVDA, SPY, ES=F, EURUSD, BTC-USD, 0700.HK, 600519. Index names like SPX do not resolve — use SPY or ES=F.
- `window` (string): Omit to follow the freshest bars. rth = US day session; asia = 09:00-16:00 Beijing; gap = the Asia-close-to-US-open stretch. gap/asia are for 24-hour instruments only.

### `close_curve` (~262 tokens)

Close distribution curve (P(close above each level))

The full probability curve of where today's US regular session closes: for any set of price levels, the probability that the session close prints above each one. Distances are measured in units of today's own volatility (ATR of the first 90 minutes) against 1,906 historical sessions grouped by day type. Validated against real-money prediction-market prices: on tail levels (>=0.5% from spot) this curve's log-loss beat Polymarket's own 'SPY closes above $K' ladder quotes in two independent windows; near the money the market was MORE accurate — use this for shape and tails, not direction. Available from 90 minutes into the day session. Same key and quota as price_action_read. Historical frequencies, not forecasts.

Input parameters:

- `levels` (array): Price levels to evaluate. Omit for an automatic grid at ±0.25/0.5/1/1.5/2/3 ATR18 around the anchor.
- `symbol` (string, required): Ticker: NVDA, SPY, ES=F, EURUSD, BTC-USD, 0700.HK. Index names like SPX do not resolve — use SPY or ES=F. Built and measured on ES; other symbols are descriptive.

### `get_scoreboard` (~141 tokens)

Public forward record

The standing public record of this service's own calls — free, no key. Every US trading day at 11:00 ET the day-session read for ES=F, NQ=F and QQQ is snapshotted verbatim; after the close each row is scored on whether a new session high or low actually printed after the read. Ties score against the model, days with no live read stay visible as gaps, and no row is ever edited. Recording began 2026-08-25. Use this to verify the claims before trusting any read.

Input parameters:

- `limit` (integer): Rows to return, newest first. Default 30.

### `request_free_key` (~142 tokens)

Request a free API key by email

Request a free evaluation key (qd_...): no card, no account — the key is emailed to the address given, never returned in this response. It unlocks 10 successful calls per UTC day. Ask the human for their email address first and send marketing_opt_in=true only with their explicit consent. Full access is $99.90/month with a 3-day free trial, checkout link comes back in any quota-exhausted error.

Input parameters:

- `email` (string, required): Where the key is delivered.
- `marketing_opt_in` (boolean): Only with explicit user consent.
- `source` (string): Optional short origin tag, e.g. 'agent'.
