Polygon

You run a Polygon MCP Server to access Polygon.io market data through a local MCP endpoint. It exposes a set of tools you can call from an MCP client to get tickers, quotes, aggregates, news, and more, enabling your apps to query market data efficiently.

How to use

You connect to the Polygon MCP Server from your MCP client and call the available tools by name, supplying the necessary arguments. Use the server to check market status, fetch ticker details, retrieve real-time quotes, obtain aggregates and daily open/close prices, pull ticker news, list available tickers, and get snapshot data. Each call targets a specific tool and returns structured data that you can integrate into dashboards, alerts, or trading workflows.
