get_technical_indicators
AI agents call get_technical_indicators to retrieve information from A Share without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves technical indicators (technical analysis data) for A-shares, which is a read-only data query operation. It has no capability to modify, execute operations, delete data, or conduct financial transactions. The blast radius of misuse is minimal—an AI agent could only retrieve unwanted financial data, not cause harm.
From the tool's definition Tool name contains 'get_' prefix indicating retrieval operation. Server description states it provides 'data query' functionality including 'technical indicators' with 'no side effects' implied by query-only context.
