Delete a chat session.
AI agents call delete_chat to permanently remove resources in Sure MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs a delete operation that removes a chat session without the ability to undo the action. While the severity is not critical because chat history loss has limited financial or operational impact compared to account or transaction deletion, it remains destructive in nature.
From the tool's definition Tool name 'delete_chat' and description 'Delete a chat session' indicate irreversible deletion of data.
