Summary
Connects Claude to Polygon.io's financial data APIs for stocks, options, and crypto. You get ticker search, OHLC aggregate bars, daily open/high/low/close with after-hours data, and news feeds. It's hosted through Pipeworx's gateway, which means you can either use this server standalone or tap into their broader collection of 250+ data sources. The ask_pipeworx tool lets you query in plain English instead of calling specific endpoints. Reach for this when you need real market data in your AI workflows without writing your own Polygon.io integration.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
