InsightSentry

MCP server and CLI for the InsightSentry financial data API.

Gives AI assistants direct access to real-time and historical market data for equities, futures, options, crypto, forex, and more — plus comprehensive documentation resources for building applications with the InsightSentry API and WebSocket feeds. Also usable as a standalone CLI for scripting and terminal workflows.

Install

npm install -g @insightsentry/mcp

This gives you two commands:

Command	Purpose
