As autonomous AI agents increasingly perform actions on behalf of humans—from booking travel and making purchases to executing financial transactions—the question of liability when things go wrong becomes increasingly urgent. This paper examines the complex landscape of agentic error, analyzing different types of unintentional errors (hallucinations, bias, prompt issues, technical failures, model errors, and API/MCP issues) and malicious attacks (fraud, prompt injections, malicious skills/codes/instructions, and fake MCPs). We use a simple example scenario—a user requesting "I want to eat Italian pizza" where an AI agent misinterprets the request and purchases non-refundable air tickets to Italy and makes a reservation at a highly rated restaurant—to illustrate the complexity of liability allocation. We review existing frameworks for contract law, tort law, product liability, and agency law, which are predominantly human-centric and ill-suited for agentic AI. We examine how different entities in the agentic AI ecosystem—users, developers, deployers, tool providers, model providers, and infrastructure providers—share (or fail to share) responsibility. The paper proposes a framework for cross-jurisdictional regulatory cooperation, drawing on existing initiatives like the EU AI Act, OECD Global Partnership on AI (GPAI), and G7 Hiroshima Process. We recommend a layered liability framework that allocates responsibility based on control, foreseeability, and the ability to prevent or mitigate harm, with special provisions for cross-border transactions and international cooperation.
