Try the live demo Sentinel AI is a lightweight, zero-dependency safety layer that protects your LLM applications from prompt injection, PII leaks, harmful content, hallucinations, and toxic outputs — with sub-millisecond latency. Why Sentinel AI? - Fast : 0.05ms average scan latency. No GPU required. No API calls. - Comprehensive : 11 built-in scanners covering the OWASP LLM Top 10. - Zero heavy dependencies : Core library needs only regex . No PyTorch, no transformers. - Drop-in integrations : Works with Claude, OpenAI, LangChain, LlamaIndex, and any LLM. - Production-ready : Auth, rate limiting, webhooks, OpenTelemetry, streaming protection. - Complementary to model-based security : Use as a deterministic first-pass filter alongside AI-powered tools like Claude Code Security. Catches known attack patterns instantly so the model can focus on harder security questions. Architecture Installation Claude Code Plugin (recommended) Then use /sentinel-ai:scan , /sentinel-ai:check-pii , and /sentinel-ai:check-safety commands directly in Claude Code. The plugin also includes an auto-invoked safety-scanning skill and 4 MCP tools. Python Package Or install directly from GitHub: With optional integrations: JavaScript / TypeScript Standalone scanning in Node.js, Deno, Bun, and browsers — zero runtime dependencies. The JS SDK includes CodeScanner (OWASP Top 10), DependencyScanner (supply chain attacks), PromptHardener , CanaryT","default_branch":null,"files":null,"tree":[],"storefront":"/r/MaxwellCalkin","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/MaxwellCalkin/sentinel-ai/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
