## Quality 83/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_coin_summary (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_exchanges (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_market_overview (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,049 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 7, about 1,049 tokens to load them all
- tool set hash: f56b565af1b0a88fddeb4ad50b575dea
- badge: [![protogrid quality](https://protogrid.dev/badge/com.coinfuty/coinfuty.svg)](https://protogrid.dev/servers/com.coinfuty/coinfuty)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (7)

- `get_coins_markets`: List coins with live futures market data: price, 1h/24h/7d price change, open interest (with 24h change), current funding rate (OI-weighted, % per interval), 24h volume, 24h liquidations, 24h long/short ratio, and market cap. Sortable; filter to specific symbols with `symbols`.
- `get_coin_summary`: Full derivatives snapshot for one coin: price and market cap, open interest with 1h/4h/12h/24h change, volume, liquidations (total/long/short), long/short ratio per exchange, and current funding rate per exchange (OI-weighted aggregate included). The single best tool for “what's happening with X futures”.
- `get_exchange_breakdown`: How one coin's futures activity splits across exchanges. metric=oi returns each exchange's open interest USD with 1h/4h/12h/24h % change (window ignored); long_short returns ratio + taker buy/sell volume per exchange; liquidation returns long/short liquidation USD; volume returns traded volume USD with % changes. `total` is the coin-level aggregate.
- `get_funding_rates`: Current and accumulated funding rates for one coin on every exchange that lists it: current rate (% per settlement interval, stablecoin- and token-margined), accumulated 1d/7d/30d/1y, settlement interval hours, and next funding time. Includes the OI-weighted aggregate rate.
- `get_market_overview`: Aggregated crypto futures market snapshot: total open interest (USD, with 1h/24h % change), total liquidations (24h), Fear & Greed index, average RSI across coins, plus a 30-day daily series of open interest and liquidations. Data aggregated across major exchanges.
- `get_price_history`: Historical time series for one coin. metric=price returns OHLC candles with volume; oi returns open-interest candles (USD); funding returns OI-weighted funding-rate candles (% per interval); long_short returns ratio + taker buy/sell volume; liquidation returns long/short liquidation USD; volume returns taker buy/sell volume USD. Timestamps are UTC ISO 8601, newest N points.
- `list_exchanges`: Top cryptocurrency derivatives exchanges tracked by Coinfuty, with open interest, 24h volume, 24h liquidations, futures maker/taker fees, number of markets, and CMC rank.
