WHAT IT DOES

What get_elements_in_region does on KiCAD-MCP-Server

AI agents call get_elements_in_region to retrieve information from KiCAD-MCP-Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_elements_in_region is rated Low

This tool queries and retrieves schematic elements within a bounded area. It has no side effects, does not create, modify, delete, or execute operations. It is a straightforward data retrieval function, fitting the Read category with low severity since misuse would only expose information already accessible to an agent with schematic access.

From the tool's definition Tool description states 'List all symbols, wires, and labels within a rectangular region' — a pure retrieval operation with no modification capability. The phrase 'before modifying it' indicates it is intended for inspection, not action.
