Cyntrisec Cli Overview

The cyntrisec/cyntrisec-cli MCP server exposes locally stored AWS security analysis to AI clients, including scan summaries and discovered attack paths. Its underlying CLI historically assumes an AWS role, reads infrastructure through AWS APIs, normalizes assets and relationships, and builds a capability graph. Graph searches identify paths from internet-facing resources to sensitive targets, while cut and cost analysis supports remediation prioritization. Reach for it when you need read-only AWS relationship analysis and agent-accessible security findings, but treat it as historical software and review all generated remediation guidance.

Primary Use Cases for Cyntrisec Cli:

Scan AWS infrastructure through an assumed role
Review discovered attack paths from internet-facing resources
Prioritize remediation cuts by security impact and estimated cost
Identify unused capabilities that increase blast radius
