Get the current spot price for a crypto asset from Coinbase.

Args: symbol: Base ticker, e.g. "BTC", "ETH", "SOL". A trailing "-USD" or "/USD" is tolerated and stripped.

Get OHLCV candles for a crypto asset from Coinbase.

Args: symbol: Base ticker, e.g. "BTC", "ETH", "SOL". granularity: One of "1m", "5m", "15m", "1h", "6h", "1d". limit: Number of candles to return (max 300).

Get an order book snapshot for a crypto asset from Coinbase: best bid and ask, spread in basis points, and a bid/ask volume imbalance metric computed over the top depth levels.

Args: symbol: Base ticker, e.g. "BTC", "ETH", "SOL". depth: Number of price levels per side to aggregate over (max 50). include_levels: Return the raw price/size ladder as well. Off by default because the ladder is depth pairs per side and the summary fields above answer most questions; turn it on only to walk the book or size an order against real resting liquidity.

Get the current perpetual futures funding rate for a crypto asset from Hyperliquid, along with mark price and open interest.

Args: symbol: Base ticker, e.g. "BTC", "ETH", "SOL".

Compute technical indicators (RSI-14, EMA-20/50, ATR-14, annualized realized volatility) for a crypto asset from recent Coinbase candles. All math is implemented from scratch on the standard library; see market_pulse_mcp/indicators.py.

Args: symbol: Base ticker, e.g. "BTC", "ETH", "SOL". granularity: Candle granularity: one of "1m", "5m", "15m", "1h", "6h", "1d". Determines both the indicator timeframe and the annualization factor used for realized volatility. limit: Number of candles to pull (more history gives a more stable EMA-50; at least 15 candles are required for RSI-14/ATR-14).

Compact multi-asset summary table combining price, spread, funding rate, and RSI/trend for each symbol in one call. Useful for a quick market scan without calling the individual tools per asset.

Args: symbols: List of base tickers, e.g. ["BTC", "ETH", "SOL"].

Compare Coinbase spot against the Hyperliquid perpetual for each asset: spot-perp basis in basis points, the current funding rate, and what the two together say about positioning.

Positive basis means the perp trades above spot (contango), which usually pairs with positive funding and crowded long positioning; negative basis (backwardation) with negative funding points the other way. Basis and funding disagreeing is the interesting case, so both are always reported rather than collapsed into one score.

Args: symbols: List of base tickers, e.g. ["BTC", "ETH", "SOL"]. Each must be listed on Coinbase spot and as a Hyperliquid perp; assets missing from either venue come back with an error on that row.

List which crypto assets this server can actually answer for, and on which venue. Call this before a scan rather than discovering coverage by watching individual symbols fail.

Coverage is not uniform. Coinbase quotes the spot side and Hyperliquid the perp side, and the two venues list different assets: some are spot-only (price, candles, order book, indicators work; funding does not), some are perp-only (funding works; nothing Coinbase-sourced does), and only assets on both venues support basis.

Args: venue: Which slice to return. "both" (default) is the spot-and-perp intersection, i.e. exactly the assets basis works for. "spot" is every Coinbase USD market, "perp" every Hyperliquid perp, "spot_only" and "perp_only" the two exclusive sets. search: Optional case-insensitive substring filter, e.g. "SOL". limit: Maximum symbols to return. Counts are always exact and are reported regardless of how many symbols the list itself was truncated to.
