mcp-pickaxe Destructive Risk 5/5

// WHEN AI AGENTS USE THIS TOOL

AI agents may call user_delete to permanently remove or destroy resources in Mcp Pickaxe. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

// WHY ENFORCE A POLICY ON USER_DELETE

Without a policy, an AI agent could call user_delete in a loop, permanently destroying resources in Mcp Pickaxe. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

// RECOMMENDED POLICY

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.
