Metis: AI-Powered Open-Source Security Code Analyzer
▼ Summary
– Metis is an open source AI tool developed by Arm’s product security team to help engineers conduct deep security reviews on code.
– It uses LLMs with semantic reasoning to identify subtle flaws that traditional static analysis tools and manual reviews often miss.
– The tool employs retrieval augmented generation to incorporate broader codebase context for more accurate and actionable suggestions.
– Metis supports multiple programming languages through a plugin system and can connect to various vector store backends while being designed for future model provider expansion.
– It is freely available on GitHub for public use.
Metis offers a powerful, AI-driven approach to security code analysis, helping developers identify subtle vulnerabilities that traditional scanners often miss. Developed by Arm’s product security team, this open-source tool tackles the challenge of securing large or legacy codebases where conventional methods fall short.
Unlike standard linters and static analysis systems that rely on predefined signatures or pattern matching, Metis leverages large language models capable of semantic reasoning. This allows it to understand the deeper meaning and context within the code, uncovering flaws that might escape both automated tools and manual inspection. The objective is twofold: to catch elusive security issues and to significantly reduce the fatigue associated with lengthy code reviews.
A key feature of Metis is its use of retrieval augmented generation. This technique enables the tool to pull relevant context from across the entire codebase. By understanding how different parts of the code relate to each other, the model can generate more precise and actionable recommendations for developers.
The tool is built with flexibility in mind. It supports a range of programming languages, including C, C++, Python, Rust, and TypeScript, through a plugin-based system that can be extended to incorporate others. For data storage, it is compatible with various vector store backends like PostgreSQL with pgvector and ChromaDB. While it currently integrates with OpenAI as its language model provider, the architecture is designed to accommodate additional providers down the line.
Metis is freely available on GitHub for anyone to use and contribute to.
