What stockSplit does on Itick
AI agents call stockSplit to retrieve information from Itick without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why stockSplit is rated Low
This tool queries historical stock split and adjustment factor data from the market data API. It performs a read-only operation to fetch adjustment factors used in financial calculations, similar to sibling tools (batch_quotes, single_kline, etc.) which are all Read category. No data is created, modified, deleted, or financial transactions are executed—only market reference data is retrieved.
From the tool's definition Tool name 'stockSplit' and description indicate it retrieves 'adjustment factors list' (拆股/复权等调整因子列表) via GET /stock/split endpoint. GET requests retrieve data without modifying it.
Attacks that exploit this kind of access

stockSplit is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
