AI agents call unity_spriteatlas_delete to permanently remove resources in Unity MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a SpriteAtlas is a destructive operation that cannot be undone and removes data from the project. SpriteAtlas assets are project resources, and their deletion would impact any scenes or scripts that reference them. This warrants the Destructive category with high severity due to the potential for accidental data loss affecting game builds and scene dependencies.
From the tool's definition Tool name 'unity_spriteatlas_delete' and description 'Delete a SpriteAtlas asset' indicate irreversible deletion of a game asset.

PolicyLayer is an MCP gateway — it sits between your AI agents and Unity MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for unity_spriteatlas_delete:
{
"version": "1",
"default": "deny",
"hide": [
"unity_spriteatlas_delete"
]
} unity_spriteatlas_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
