TenantGuard

Open source scanner for cross-tenant AI-agent security bugs

Visit github.comAlternativestop 25% of August 2026

What it does

TenantGuard is a purpose-built CLI and MCP server for securing multi-tenant AI-agent deployments. While broad governance tools and general IaC scanners miss agent-specific isolation defects, TenantGuard goes deep. Using 16 fail-closed OPA/Rego rules mapped to real-world vulnerabilities, it instantly catches unscoped sandbox mounts, cross-tenant cron bindings, SSRF tool URLs, and exec credential leaks. It outputs in SARIF, JSON, and MCP and is licensed with Apache-2.0.

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
