The InsightSentry tool gives developers a terminal workflow and gives AI agents direct access through MCP. Install once, then use the same API coverage from your shell, editor, or agent client.
Terminal mode
Run quotes, screeners, options, calendar, and history tools from scripts or a shell.
Agent mode
Connect the same package to MCP clients so AI agents can query market data directly.
