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. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability63
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1540 tokens (~385/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability check failed: schema churn in the 14 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 0 additions. See how to fix → Fail
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

compute_indicators Calculate indicators from your own candles ~405
Calculates indicators from prices the user gives. Use it when the user gives their own prices and wants indicators calculated, such as "calculate ATR and stochastic from these candles". Best for any asset the user has prices for: stocks, crypto, commodities or a spreadsheet column, and for atr, stochastic and vwap. Input tips: pass prices (2 to 250 candles, oldest first, each with a numeric close and optionally time, open, high, low and volume) and indicators from sma, ema, rsi, macd, bollinger, atr, stochastic and vwap; optionally periods and series_length. atr and stochastic need high and low on every candle, and vwap needs high, low and volume. Returns the latest value and a short series for each indicator, with the settings used. Makes no outside request and keeps nothing. Not for: fetching prices, forecasts, or buy or sell advice. Informational only, not financial advice; gives no signals.
| Name | Type | Req | Description |
|---|---|---|---|
| indicators | array | yes | Indicators to calculate, such as ["rsi", "macd"]: sma, ema, rsi, macd (12, 26, 9), bollinger (2 standard deviations), atr, stochastic (%K and %D) and vwap (cumulative over the given candles) |
| periods | object | – | Lookback length per indicator, in candles, such as {"sma": 50}. Any left out use the default shown. Whole numbers from 2 to 100. |
| prices | array | yes | Candles, oldest first, 2 to 250, such as [{"time": "2026-09-01", "high": 10.6, "low": 9.7, "close": 10.2}]. Prices are plain numbers in any one unit. |

get_feedback_reply Read maintainer reply to feedback ~70

get_indicators Calculate indicators for a currency pair (ECB) ~473
Calculates indicators for a currency pair. Use it when the user names a currency pair and wants indicators, such as "RSI and MACD for EUR/USD" or "50-day SMA for USD/JPY on the weekly chart". Best for the 30 ECB currencies; it reads the European Central Bank's daily euro reference rates, one closing rate a day. Input tips: pass symbol as two ISO currency codes (for example EUR/USD), interval 1d (default) or 1w, and indicators from sma, ema, rsi, macd and bollinger; optionally periods and series_length. Returns the latest value and a short series for each indicator, with the source and the date of the last rate. Not for: stocks, crypto, forecasts, or buy or sell advice. For atr, stochastic, vwap or any non-currency asset, use compute_indicators with the user's own candles. Informational only, not financial advice; gives no signals.
