Description, as the server wrote it: ```untrusted-server-text Get daily net ETF flow history for a single crypto asset over the last 30 days. Returns a time series of net USD millions per day (positive = inflow, negative = outflow). Figures are asset-level totals; the per-fund breakdown (IBIT, FBTC, ETHA and others) is returned by get_fund_flows. ``` ### `get_cefi_index` - The name "get_cefi_index" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Returns the composite CEFI (Crypto ETF Flow Index): a 0–100 index of money moving through US spot crypto ETFs on all 16 tracked assets. Net flows of all funds are added up in dollars, and three components are scored against the past year: flow (today's net flow, smoothed, 40%), trend (net flow over 20 trading days, 30%) and breadth (share of funds with inflows, 30%). 50 = zero net flow; a typical inflow day scores about 69, a typical outflow day about 31. Each component is on the same 0–100 scale. Zones: 0–20 extreme fear, 20–40 fear, 40–60 neutral, 60–80 greed, 80–100 extreme greed. ``` ### `get_flows_summary` - The name "get_flows_summary" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get the latest-day net ETF inflow/outflow (USD millions) for every tracked crypto asset: BTC (Bitcoin), ETH (Ethereum), SOL (Solana), XRP, HYP (Hyperliquid), DOGE (Dogecoin), LINK (Chainlink), AVAX (Avalanche), HBAR (Hedera), LTC (Litecoin), BNB, DOT (Polkadot), SUI, NEAR, TRX (TRON) and ZEC (Zcash). Positive = inflow, negative = outflow. Flows are published one business day in arrears, so `referenceIsToday` is normally false: the figures belong to `referenceDate`, the last trading day published, not to the current date. On Mondays the freshest data is Friday's. `totalUsdM` is the sum across all assets. Figures are asset-level totals; the per-fund breakdown (IBIT, FBTC, ETHA and others) is returned by get_fund_flows, net assets by get_funds. ``` ### `get_fund_flows` - The name "get_fund_flows" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get daily net flows of every spot ETF on one crypto asset, fund by fund (IBIT, FBTC, ETHA, …), over the last 30 days. Each trading day lists the funds trading that day with ticker, issuer and net USD millions (positive = inflow, negative = outflow), plus `totalUsdM` for the day. `netFlowUsdM` is null when there is no figure for the fund that day, usually because it has not reported yet; 0 means no creations or redemptions. Flows are published one business day in arrears. ``` ### `get_funds` - The name "get_funds" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get the US spot crypto ETFs that have started trading, for one asset or all 16: ticker, name, issuer, exchange, listing date, sponsor fee (percent per year), current net assets (`netAssetsUsdM`, USD millions) and coins held, plus the total net assets of each asset. Net assets are a current snapshot, not a history. `netAssetsBasis` is reported (published by the issuer for `netAssetsDate`), repriced (the latest published figure moved to that day by the NAV change of other funds) or estimated (coins times price, for issuers without daily holdings). `coinsHeld` is null for issuers that do not publish holdings in coins. ``` ### `get_prices` - The name "get_prices" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get current spot prices (USD) and 24-hour percentage change for all 16 tracked crypto assets: BTC, ETH, SOL, XRP, HYP, DOGE, LINK, AVAX, HBAR, LTC, BNB, DOT, SUI, NEAR, TRX, ZEC. Prices are sourced from major exchanges and refreshed frequently. ``` ### `get_weekly_analytics` - The name "get_weekly_analytics" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get 7-day aggregated ETF flow analytics for all tracked assets. Returns total net flow, the number of trading days in the window, average flow per trading day, and count of positive vs negative days per asset. Weekends are excluded. A compact momentum summary without the full daily series. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `cryptoetf`: ```json { "permissions": { "allow": [ "mcp__cryptoetf__get_flows_summary", "mcp__cryptoetf__get_asset_flows", "mcp__cryptoetf__get_fund_flows", "mcp__cryptoetf__get_funds", "mcp__cryptoetf__get_cefi_index", "mcp__cryptoetf__get_prices", "mcp__cryptoetf__get_weekly_analytics" ], "ask": [], "deny": [] } } ```
