ToolFuzz is an open-source framework designed to automatically generate diverse fuzzing scenarios that probe the tool-calling logic of AI agents. By injecting malformed inputs and varying tool invocation sequences, it identifies edge cases and failure modes. Developers can customize fuzzing strategies, track coverage metrics, and visualize results in real time, enabling efficient debugging and reliability improvement of agent-driven applications.

What is ToolFuzz?
ToolFuzz provides a comprehensive fuzz testing framework specifically tailored for tool-using AI agents. It systematically generates randomized tool invocation sequences, malformed API inputs, and unexpected parameter combinations to stress-test the agent’s tool-calling modules. Users can define custom fuzz strategies using a modular plugin interface, integrate third-party tools or APIs, and adjust mutation rules to target specific failure modes. The framework collects execution traces, measures code coverage for each component, and highlights unhandled exceptions or logic flaws. With built-in result aggregation and reporting, ToolFuzz accelerates the identification of edge cases, regression issues, and security vulnerabilities, ultimately strengthening the robustness and reliability of AI-driven workflows.
