In a SolidWorks MCP server, read-only tools like list_features or get_mass_properties brought the server's part to the front on every call, switching away from whatever document the engineer had open. A guard snapshot taken before every call did the same. The contributor's new test failed on 14 of 15 tools before the fix (SolidWorks 2026 SP4.1). An agent that only reads still changed what the person at the desk was looking at.
