Alpaca MCP — real-time US stock market data via the Alpaca Market Data API
Alpaca MCP — real-time US stock market data via the Alpaca Market Data API. That is what the mcp mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
The server publishes 3 tools. What each one is for:
alpaca_snapshot — Real-time US stock snapshot with extended-hours coverage: latest trade price, bid/ask quote, today's OHLCV, previous close, change and change % vsalpaca_bars — Historical US stock OHLCV bars with per-bar VWAP and trade count. Timeframes 1Min/5Min/15Min/1Hour/1Day; intraday bars include pre-market andalpaca_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)Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP's toolset — alpaca_snapshot, alpaca_bars, alpaca_intraday_vwap — is a fair guide to whether it matches your workflow. It is maintained by mojibake-ai; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
