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\" }) |\n| `alpaca_bars` | 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\" }) |\n| `alpaca_intraday_vwap` | 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\" }) |\n\n## Quick Start\n\nAdd to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):\n\n```json\n{\n  \"mcpServers\": {\n    \"alpaca\": {\n      \"url\": \"https://gateway.pipeworx.io/alpaca/mcp\"\n    }\n  }\n}\n```\n\n### What this endpoint actually serves\n\n`tools/list` at `https://gateway.pipeworx.io/alpaca/mcp` returns the tools in the table\nabove **plus the shared Pipeworx meta-tools** — `ask_pipeworx`,\n`discover_tools`, `search_within`, `remember`/`recall` and the rest of the\ngateway-wide set. So the tool count you see is larger than this table: a\nsingle-pack endpoint currently lists roughly 30 shared tools alongside the\npack's own. The connection's `initialize` response states its exact scope, and\nis the authoritative answer for a given day.\n\nThis is deliberate, not multiplexing by accident. The meta-tools are what let a\nscoped connection answer a question this pack does not cover — via\n`ask_pipeworx`, which routes across the whole catalog — without you adding a\nsecond MCP server. There is currently no way to mount a pack endpoint without\nthem; if the extra schemas cost you more context than the routing is worth,\nconnect to the full gateway once rather than to several pack endpoints.\n\nOr connect to the full Pipeworx gateway to get every pack's tools listed\ndirectly, instead of just this one's:\n\n```json\n{\n  \"mcpServers\": {\n    \"pipeworx\": {\n      \"url\": \"https://gateway.pipeworx.io/mcp\"\n    }\n  }\n}\n```\n\nBoth URLs reach the same gateway and the same 1476+ data sources. The\nonly difference is which pack's tools are listed **directly**; `ask_pipeworx`\nreaches all of them from either one.\n\n## Using with ask_pipeworx\n\nInstead of calling tools directly, you can ask questions in plain English —\nthis works on the pack endpoint above as well as on the full gateway:\n\n```\nask_pipeworx({ question: \"your question about Alpaca data\" })\n```\n\nThe gateway picks the right tool and fills the arguments automatically.\n\n## More\n\n- [Docs and guides](https://pipeworx.io/docs)\n- [pipeworx.io](https://pipeworx.io)\n\n## License\n\nMIT\n",
