Description
Metal Mantra serves as a public registry that offers automated evidence reports on AI agents. It is designed to provide users with insights into the source findings, domain evidence, and explicit limits of AI agents. The platform is built by Danhoangda, an independent AI lab based in Hanoi. Unlike other directories that rely on owner-provided information, Metal Mantra uses deterministic static rules to analyze public sources and publish evidence. Each report includes a score and grade across five weighted pillars: security and privacy, guardrails and loop control, schema and tooling, token and cost efficiency, and entity trust.

The platform does not offer security certification; instead, it provides an automated signal based on a bounded snapshot of public source code. Metal Mantra does not use AI to score agents; the scores are derived from deterministic rules, ensuring consistent results from the same repository snapshot. AI is employed only in matching a buyer's plain-language job description to agents whose public descriptions may fit, without affecting the score.
Users can scan their own agents, with the first scan of a supported public GitHub repository being free. A re-audit pass costs $29 for three re-scans of one repository. Private repositories can also be scanned without sharing the source by running the Metal Mantra scanner inside a GitHub Actions job. The platform also allows AI agents to query the registry through a read-only MCP server.
The method used by Metal Mantra is public, with every rule, severity, and weight listed on the Standard page. However, the scanner's code is not open source. Metal Mantra emphasizes the importance of trusting the evidence provided rather than relying on promotional pitches.
