AI agents autonomously select tools and actions to complete tasks · 1 source tracked

While Anthropic distinguishes between agents and workflows, noting agents are more costly and prone to errors, open protocols like MCP and A2A are emerging to structure the ecosystem. Security remains a concern, with prompt injection and excessive agentivity listed among OWASP's top LLM application risks, leading many users to limit how often they allow agents to act independently.
