Evidra – a fail-closed MCP guardrail for AI infrastructure ops
by vitass·Mar 3, 2026·1 point·1 comment
AI Analysis
●●●BangerSolve My ProblemWizardry
Fail-closed guardrail for AI agent infrastructure access—kills unsafe ops before they ship.
Strengths
- •Fail-closed default (deny unless explicitly safe) is the correct stance for production access
- •SHA-256 hash-chained evidence log makes tampering detectable and auditable
- •OPA policy engine sidesteps natural language brittleness of pure LLM safety measures
Weaknesses
- •Early project (6 stars, 0 issues public)—real-world deployment feedback lacking
- •Requires structured tool invocation; won't protect against shell injection or unstructured agent output
