Description
Read-only crypto research skills that check a price, RSI and ATR against independent sources.
What our measurements say
Nota is a remote MCP server published at nota-ryo.vercel.app. It has been probed 6 times since 9/12/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 422 ms, placing it among the faster endpoints. It offers a narrow, focused set of 4 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names explicitly reflect their purpose (e.g., 'price_crosscheck' for price validation).
- Descriptions tie use cases to specific functions (e.g., 'news_verify' for claim corroboration).
Weaknesses
- Parameter names like 'reference_path' lack contextual clarity.
- No explicit error handling or constraint documentation in tool descriptions.
- Optional parameters (e.g., 'hours' in 'narrative_convergence') lack default value guidance.
narrative_convergence— Parameter 'tokens' is optional but unclear how it interacts with 'voices'.price_crosscheck— 'reference_path' parameter name is ambiguous without context.technicals_crosscheck— No mention of handling invalid symbols or missing OHLC data.

Risk: low
Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 164ms → warm 154ms (penalty 10ms)
Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
narrative_convergenceMonitor up to 20 user-selected voices (Telegram public channels, X handles) and report which tokens they mention, lexicon-scored sentiment, conviction and urgency, and whether several voices converge on one narrative.
voicesarrayrequiredtokensarrayhoursinteger
news_verifyVerify a crypto news claim: count independent sources reporting it, score corroboration, and attach the token's RYO analyze_token evidence so the story and the market read sit side by side.

price_crosscheckFetch independent USD spot prices for a symbol from CoinGecko, Coinbase and Kraken (no keys), report median and spread, and flag how far a reference price (e.g. RYO's) deviates from the exchanges.

technicals_crosscheckRecompute RSI(14), ATR(14) and 1d/7d/30d performance from CoinGecko public OHLC (Wilder smoothing, daily candles) and report how far reference values (e.g. RYO's) deviate from the independent calculation.
