## 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**: 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**: 85/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2103 tokens (~105/item across 20 items; 9 tools + 11 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 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.
  - 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 9 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 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.

### `narrative_convergence` (~145 tokens)

Narrative Convergence

Monitor up to 20 user-selected voices (Telegram public channels, Bluesky and X handles) and report which tokens they mention, lexicon-scored sentiment per token, conviction and urgency, and whether the voices converge: at least two voices carry a non-zero net sentiment on the token and every one of them has the same sign.

Input parameters:

News Verify

Verify a crypto news claim: count independent domains reporting it (four outlets' RSS headlines plus Tavily or Venice web search), count those whose headline leans the opposite way, and attach the token's RYO analyze_token evidence so the story and the market read sit side by side.

Technicals Crosscheck

Recompute RSI(14) and ATR(14) (Wilder smoothing) from 200 closed UTC-day candles (OKX, else Binance, else CoinGecko 4h OHLC aggregated to days) plus 1d/7d/30d performance, and report how far reference values (e.g. RYO's) deviate from the independent calculation.

Input parameters:

### `positioning_check` (~277 tokens)

Positioning Check

Decide, field by field, whether RYO's deep_analysis derivatives block can be cited as evidence about this token (identical values across other tokens, sign conflicts with OKX coin-terms open interest), and report OKX perp positioning: premium over spot on OKX and Hyperliquid, 24 h open-interest change in coins, long/short account ratio and its 100-hour percentile, and for BTC/ETH Deribit's DVOL implied 7-day move as a check on stop distance.

Input parameters:

- `atr_stop_pct` (number): Stop distance in % of price (e.g. RYO's 1.5 x atr_14_pct), checked against the DVOL implied 7-day move
- `peer_derivatives` (array): Same-day RYO derivatives blocks for other symbols: [{symbol, funding_rate_bps, open_interest_change_24h_pct}]; taken from the day's scorecard locks when omitted
- `reference_derivatives` (object): RYO deep_analysis data.derivatives for this symbol; fetched from RYO when omitted and a RYO key is set
- `ryo_btc_funding_bps` (number): Latest BTC funding from RYO monitor_market_sentiment_shift (evidence.funding.latest_bps)
- `symbol` (string, required): Token symbol, e.g. SOL

### `move_base_rate` (~215 tokens)

Move Base Rate

Empirical probability that a token moves k ATRs (up or down, touched or closed beyond) within h days, counted from ~400 days of OKX daily candles on days in the same ATR tercile as today, with a time-split holdout. Pass RYO's atr_14_pct to measure the distance in RYO's ATR; k=0 with event=close gives the plain 'higher after h days' rate.

Input parameters:

- `as_of` (string): YYYY-MM-DD: use only candles closed before this day (scoring a past call)
- `atr_14_pct` (number): RYO's ATR(14) as % of price (analyze_token or deep_analysis)
- `direction` (string): Default up
- `event` (string): Default touch
- `horizon_days` (integer): 1 to 14 (default 3)
- `k` (number): Distance in ATRs (default 1)
- `symbol` (string, required): Token symbol, e.g. SOL

Output parameters:

- `as_of`
- `availability` (object)
- `data` (object)
- `data_mode` (string)
- `request` (object)
- `schema_version`
- `status` (string)
- `summary`
- `tool` (string)
- `trace_id`
- `warnings` (array)

### `verdict_track_record` (~120 tokens)

Verdict Track Record

How RYO's own deep_analysis plans have fared: locked daily for 25 majors and settled on OKX hourly candles (stop or +1R target first, 24 h or 72 h). Returns counts by verdict and by confluence state, plans whose verdict leans against their own direction, and the latest locked verdict. Omit the symbol for all tokens.

Input parameters:

- `horizon_hours` (integer): 24 (default) or 72
- `symbol` (string): Token symbol, e.g. SOL; omit for every token

Output parameters:

- `as_of`
- `availability` (object)
- `data` (object)
- `data_mode` (string)
- `request` (object)
- `schema_version`
- `status` (string)
- `summary`
- `tool` (string)
- `trace_id`
- `warnings` (array)

### `liquidity_check` (~107 tokens)

Liquidity Check

Macro liquidity from DefiLlama (no key): 7-day and 30-day change of the total USD stablecoin supply, and of DeFi TVL on the token's own chain (ETH, SOL, BNB, AVAX and other L1/L2 tokens). Each leg reports its own as_of and availability; a token without a chain of its own gets no TVL rather than a borrowed one.

Input parameters:

- `symbol` (string, required): Token symbol, e.g. SOL

Output parameters:

- `as_of`
- `availability` (object)
- `data` (object)
- `data_mode` (string)

- `trace_id`
- `warnings` (array)

### `crowd_odds` (~155 tokens)

Crowd Odds

Prediction-market implied probability that a token trades higher than now at a horizon: the Polymarket 'above $K on <date>' ladder (Kalshi's KX<coin>D ladder as fallback) expiring within a day of now + horizon, liquid strikes only, made monotone and interpolated at spot. BTC, ETH, SOL, XRP (and DOGE on Kalshi); null when no market.

Input parameters:

- `horizon_days` (integer): 1 to 14 (default 7)
- `spot` (number): Price to read the ladder at (default: Binance spot, which is what Polymarket's crypto ladders resolve on)
- `symbol` (string, required): Token symbol, e.g. BTC

Output parameters:

- `as_of`
- `availability` (object)
- `data` (object)
- `data_mode` (string)
- `request` (object)
- `schema_version`
- `status` (string)
- `summary`
- `tool` (string)
- `trace_id`
- `warnings` (array)

## Common questions

### What is the Nota MCP server?

Nota is an MCP server listed in the public MCP registry as io.github.PugarHuda/nota. Read-only crypto research skills that check a price, RSI and ATR against independent sources. This page covers its hosted endpoint (https://nota-ryo.vercel.app/mcp).

### Is the Nota MCP server safe to use?

Nota scores 80 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Nota MCP server expose?

Nota exposes 9 tools: narrative_convergence, news_verify, price_crosscheck, technicals_crosscheck, positioning_check, and 4 more. Their descriptions and schemas cost roughly 1,443 tokens of context every time the server is loaded.

### Does the Nota MCP server require authentication?

No. We connected to Nota without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Nota MCP server still maintained?

Nota is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
