More details
What is Flint AI CLI?
Flint AI CLI is a tool that scans AI agent source code for security vulnerabilities, misconfigurations, and quality issues, and evaluates agents at runtime using adversarial and functional prompts. It provides a reliability score for each agent, with findings mapped to OWASP ASVS 3.0–3.1 and scored using CVSS v4.
How does Flint AI CLI compare to alternatives?
Unlike cloud-based solutions, Flint AI CLI keeps your source code local, reducing the risk of data exposure
Compared to manual analysis and evaluation, Flint AI CLI automates the process, saving time and effort
What integrations and ecosystem support does Flint AI CLI offer?
Support for major agent frameworks, including Claude Agents SDK, LangChain, and OpenAI SDK
Integration with LLM providers, such as OpenAI, Anthropic, and Google Gemini, with support for free-tier API keys
What are the pros and limitations of Flint AI CLI?
Pros: free to use; local-first approach; framework-agnostic; automated analysis and evaluation
Limitations: requires a Python 3.13+ environment and an LLM API key; may require additional setup and configuration for some users
