## 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 2026-10-02.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (unsubscribe).
  - 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
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 993 tokens (~76/item across 13 items; 13 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100

## MCP tools (13)

### `get_market_structure` (~192 tokens)

SPX Market Structure

Current computed SPX dealer market structure (walls, gamma flip, net GEX, regime), recomputed ~every 10s during market hours: scored pressure-point strike ladder, implied 50%/80% forecast-band ranges, strike activity (volume/OI), and VIX term-structure context. Also the 0DTE ATM-straddle expected move and its session fence, max pain, the running session open/high/low with the prior close and gap, order-flow measurements, a top-10 net-GEX strike profile, and chain vanna/charm totals with a top-10 strike ladder. Realtime requires a funded X-API-Key (create one at https://zdte.ai/agent/credits); without a key this serves a delayed headline preview only (regime, spot, walls, gamma flip, net GEX). Data only -- not investment advice or a trade recommendation.

### `get_regime` (~37 tokens)

SPX Dealer Regime

Current SPX dealer regime label + confidence only. Realtime with an X-API-Key; without a key this serves a delayed preview.

### `get_day` (~62 tokens)

Replay a Trading Day

Per-day SPX market-structure timeline + summary for one replay date (YYYY-MM-DD). Data only -- not investment advice or a trade recommendation.

Access Options (Prices and Onboarding)

Free pricing and accountless access instructions. Start here; no website account required.

### `create_guest_key` (~42 tokens)

Free balance check for the API key in this connection's HTTP header. Never pass a key as an argument.
