codesafer

codesafer is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from goldmembrane/cleaner-code. Its token cost is not measured, scanned A, original, MIT.

A local scanner for code produced by AI that checks for hidden Unicode characters, Trojan Source attacks, and supply-chain threats. Trojan Source attacks use misleading text direction or characters to make code appear different from what it does.

In plain words
What is it for?
Use it to inspect AI-generated code before accepting or running it.
Why use it?
It helps reveal security risks that may be invisible during a normal code review, including deceptive source text and potentially unsafe dependencies.

Security

Grade A, and why

codesafer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
