Anthropic launches free OSS Scanner powered by Claude Mythos for open-source projects
Anthropic has launched OSS Scanner, a free opt-in vulnerability scanner powered by Claude Mythos that delivers unreviewed AI security reports to open-source and crypto maintainers.

Anthropic has launched OSS Scanner, a free opt-in vulnerability detection tool designed for critical open-source and cryptocurrency projects. The system relies on Anthropic's strongest cybersecurity models, including Claude Mythos, to scan codebases for vulnerabilities and flag potential security issues.[2][3][5][6]
Core maintainers can enroll in the program by submitting a pull request on GitHub, with PostgreSQL and OpenSSL already serving as early testers. According to Anthropic, the tool delivers AI-generated vulnerability reports directly without human review, though reports can occasionally contain errors.[1][2]
Crypto projects have also sought access to the scanner. Cointelegraph reported that Ethereum client Nethermind and Bitcoin wallet ZEUS have applied for the program. Meanwhile, Crypto Briefing noted that offering free scans could bolster Anthropic's market standing and influence AI model competition dynamics by 2026.[4][7][8]

Anthropic is now offering crypto and open-source projects access to its new AI security scanner. The opt-in service uses Anthropic’s strongest cybersecurity models, including Claude Mythos, to scan codebases for vulnerabilities and report potential security issues. AI is becoming capable of finding vulnerabilities that traditional security tools can miss. For crypto, where one overlooked bug can put billions of dollars at risk, AI-powered security could become a major part of how protocols protect themselves.
