WHAT IT DOES

What get_wire_connections does on KiCAD-MCP-Server

AI agents call get_wire_connections 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.
