webmap_remove_layer
AI agents call webmap_remove_layer to permanently remove resources in ArcGIS MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The name indicates removal of a layer from a web map, which is typically a destructive, hard-to-reverse operation. No description is provided to clarify reversibility, but 'remove' in GIS contexts generally means permanent deletion rather than a soft toggle. Severity is high given the blast radius of losing configured layers in a shared web map in ArcGIS Online/Enterprise.
From the tool's definition Tool name 'webmap_remove_layer' — 'remove' strongly implies irreversible deletion of a layer from a web map.
