 Additionally, AI agents that have access to tools can implement business logic procedures and/or authentication and authorization mechanisms that sometimes can be bypassed if the defined workflow is not followed. This test aims to assess whether it is possible to induce the agent to directly invoke one or more tools chosen by the attacker, using parameters provided by the attacker, with the goal of bypassing any authentication and/or authorization mechanisms implemented within the agent but not replicated in the tools, or to exploit potential application vulnerabilities in the tools used by the agent (e.g. SQL Injection).
 
-### Tools
+#### Tools
 In the context of AI agents, tools are functions that the agent can use to interact with external system and services and to perform tasks beyond its abilities. The LLM models underlying AI agents are engines capable of understanding natural language and generating reasoning. Thanks to tools, the capabilities of these systems increase significantly, as the LLM model has the ability to put its reasoning into practice and perform actions to solve a specific problem. 
 
 Initially, tools were static set of functions coded for a specific AI agent. Then new protocols have beeen developed, like the Model Context Protocol (MCP), where the tool integration is standardized and decoupled from the specific LLM application.
 
 Regardless of the type of tool, tools significantly expand the capabilities of LLMs, but they also **increase the attack surface**. When analyzing an AI Agent that has access to tools, it is important to assess the security of those tools. They may present both **traditional application vulnerabilities** (e.g., SQL Injection) and issues specific to Generative AI applications, usually caused by **insecure design**.
 
-### Design considerations for AI agents and tools
+#### Design considerations for AI agents and tools
 At present, prompt injection issues can be mitigated but not completely prevented in systems based on LLMs. Moreover, LLMs can exhibit non-deterministic behavior because of the temperature parameter. These facts can make implementing security controls very challenging and should be taken into account when designing an LLM-based system. Security controls, whenever possible, should be implemented outside of the agent’s control, specially authentication and authorization ones. 
 
 Taking authorization controls as an example, the design of an external tool used by an AI agent to retrieve user data should internally implement all authentication and authorization checks in a non-agentic manner, returning to the agent only the data belonging to the user who is currently using it. An incorrect way to implement this is to rely on information coming from the AI agent to select the data, since a prompt-injection attack could bypass any controls implemented.
