AI agents call smartsheet_delete to permanently remove resources in Smartsheet MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Row deletion from a Smartsheet is a destructive operation that cannot be undone and results in permanent data loss. This places it in the Destructive category, which is more severe than Write. High severity is appropriate given that an AI agent with misuse could permanently delete critical rows from shared collaboration documents, affecting multiple users and potentially causing significant business impact.
From the tool's definition Tool name 'smartsheet_delete' and description 'Delete rows from a Smartsheet' explicitly perform row deletion, which is irreversible data destruction.
Documented attack patterns abuse exactly the kind of access smartsheet_delete gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Smartsheet MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for smartsheet_delete:
{
"version": "1",
"default": "deny",
"hide": [
"smartsheet_delete"
]
}smartsheet_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
