## 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 2026-10-23.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - 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**: 76/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 839 tokens (~167/item across 5 items; 4 tools + 1 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**: 90/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 67% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **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 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).
  - Supports UI / widget rendering.

Get stock or ETF performance and risk

Use this when the user asks how a single US stock or ETF has performed or how risky it is: YTD, 1-year and 5-year annualized returns, max drawdown, Sharpe, Sortino, beta and alpha, with a 1Y/5Y chart. End-of-day data for US large and mid caps, major foreign stocks and US ETFs. Not for intraday quotes, news, earnings, fundamentals or price targets.

- `security` (object)
- `url` (string)

### `compare_securities` (~125 tokens)

Compare stocks or ETFs

Use this when the user wants to compare 2 to 5 US stocks or ETFs side by side (e.g. "VOO vs QQQ", "SCHD or VYM?"): returns, drawdown, Sharpe, beta and how correlated they are, with an overlaid 1Y/5Y chart. End-of-day data for US large and mid caps, major foreign stocks and US ETFs. Not for intraday quotes or recommendations on what to buy.

Input parameters:

- `securities` (array)
- `url` (string|null): Redstone compare page (pairs only)

### `backtest_portfolio` (~133 tokens)

Backtest a stock and ETF portfolio

Use this when the user describes a portfolio of US stocks and ETFs with weights (e.g. "60% VTI, 40% BND", "equal parts AAPL, MSFT, NVDA") and wants to know how it would have done or how risky it is: returns over YTD, 1 year and 5 years (rebalanced quarterly), max drawdown, Sharpe, beta vs SPY and the correlation between holdings, charted against SPY. 2 to 20 holdings. Not for live brokerage accounts, trading or allocation advice.

Input parameters:

- `positions` (array, required)

Output parameters:

- `asOf` (string|null): Market date (YYYY-MM-DD) of the latest close behind every number
- `benchmark`: SPY, for comparison

### `screen_securities` (~286 tokens)

Screen stocks and ETFs by performance and risk

Use this when the user wants a ranked list of US stocks or ETFs by a performance or risk metric, optionally within a sector or ETF category (e.g. "lowest volatility dividend ETFs", "highest Sharpe tech stocks this year", "energy stocks with the smallest drawdown"). Covers about 1,100 US-listed stocks and about 480 US ETFs, end-of-day. Not for fundamentals (P/E, revenue), news or buy recommendations.

Input parameters:

- `filters` (array): Optional bounds in each metric's own units, e.g. {metric: 'beta1y', max: 1}. maxDrawdown1yPct is negative, so a drawdown smaller than 20% is {metric: 'maxDrawdown1yPct', min: -20}
