Permanently delete a form along with all its submissions and any attached file drops. This cannot be undone. This tool is flagged destructive (annotations.destructiveHint): MCP clients request user approval before executing it, and fail the call with 'No approval received' — without contacting this server — if approval is denied or unavailable (e.g. headless sessions). Nothing is deleted in that case; approve the client's permission prompt, or allowlist this tool in the client's permissions for unattended use.
