Alpaca MCP — real-time US stock market data via the Alpaca Market Data API
Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.
Tool | Description |
| Real-time US stock snapshot with extended-hours coverage: latest trade price, bid/ask quote, today's OHLCV, previous close, change and change % vs previous close, plus the latest minute bar with its VWAP — during pre-market and after-hours the minute bar IS the live extended-hours price. Answers "pre-market price of OKTA", "overnight change %", "after-hours volume and high/low". Multiple symbols comma-separated (max 20). BYOK Alpaca (free account), real-time IEX feed. Example: alpaca_snapshot({ symbols: "OKTA,AAPL", _apiKey: "key_id:secret_key" }) |
| Historical US stock OHLCV bars with per-bar VWAP and trade count. Timeframes 1Min/5Min/15Min/1Hour/1Day; intraday bars include pre-market and after-hours sessions on the IEX feed. Each bar: {t, o, h, l, c, v, vwap, trades}. Use start/end ISO timestamps or a lookback shorthand like "2h", "5d". Multiple symbols comma-separated (max 20). BYOK Alpaca (free account). Example: alpaca_bars({ symbols: "AAPL", timeframe: "5Min", lookback: "1d", _apiKey: "key_id:secret_key" }) |
| Current session VWAP for US stocks — is the price above or below VWAP right now? Fetches today's 1-minute bars from 04:00 ET (pre-market included), computes the cumulative volume-weighted average price, and compares it to the latest trade. Returns current_price, session_vwap, above_vwap, and session volume per symbol. Answers "current VWAP for BLK, AAPL, RHI, CTAS — above or below?" in one call. Multiple symbols comma-separated (max 20). BYOK Alpaca (free account), real-time IEX feed. Example: alpaca_intraday_vwap({ symbols: "BLK,AAPL,RHI,CTAS", _apiKey: "key_id:secret_key" }) |
