CodeSafer FAQs

Question 1

Is CodeSafer privacy-focused and does it upload my code?

Accepted Answer

Yes, CodeSafer is designed to be local-first. It runs entirely on your machine as a Model Context Protocol (MCP) server, ensuring that no code is ever uploaded to external servers, maintaining your privacy and data security.

Question 2

What specific types of security threats can CodeSafer detect?

Accepted Answer

CodeSafer identifies a wide range of threats including over 30 invisible Unicode variants, BiDi/Trojan Source (CVE-2021-42574), homoglyphs (CVE-2021-42694), Glassworm steganography, rules file backdoors in AI config files, typosquatting in dependencies, and obfuscated malicious code patterns.

Question 3

What is CodeSafer and what problem does it solve?

Accepted Answer

CodeSafer is an AI code security scanner designed to detect hidden threats in AI-generated code that traditional linters or human reviewers often miss. It protects against sophisticated attacks like invisible Unicode, Trojan Source, and supply chain vulnerabilities.

Question 4

Which AI coding assistants are compatible with CodeSafer?

Accepted Answer

CodeSafer integrates seamlessly with MCP-compatible AI clients such as Claude Code, Cursor, VS Code + Copilot, and Cline, allowing you to scan code and receive findings directly within your development environment.

Question 5

How does CodeSafer analyze code for threats?

Accepted Answer

It employs a hybrid detection approach: 8 deterministic static analysis scanners target known attack categories, while a CodeBERT deep learning model provides advanced AI analysis to classify code chunks, catching novel or obfuscated patterns with confidence scores.
