Secure AI agents against prompt injection, tool abuse, and data exfiltration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AI Agent Security Protect agentic AI systems from adversarial input, unsafe tool execution, data leakage, and privilege abuse with layered security controls. These are partial design sketches, not a working security boundary. Regexes/classifiers have false positives and false negatives; prompt text cannot grant permissions. Enforce tenant identity, resource scope and approved actions in the tool service using authenticated server-side context. Input signing authenticates origin, not the safety of signed content. Bind approvals to the exact operation/arguments and recheck immediately before execution. Test failure paths and concurrency before production use. ## Prerequisites - Python 3.10+ for guardrail code examples - Docker or Podman for sandbox execution - OpenTelemetry collector for audit logging - Familiarity with your agent framework (LangChain, CrewAI, Autogen, custom) - Access to policy engine (OPA/Cedar) for permission boundaries ## Threat Model — STRIDE for AI Agents AI agents introduce a unique threat surface. Apply STRIDE specifically to agentic components: | Threat | Agent-Specific Example | Control | |--------|----------------------|---------| …

How to install
mdr add sickn33/agentic-awesome-skills/ai-agent-security@sha256:e868427d541dd1caThe line at the top of this page pins the label v2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
