🛡️ AgentReady threat assessment
MAESTRO 7-layer threat model + OWASP AIVSS risk score for aws-s3-connector-mcp, derived from its capabilities.
These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification. See the scoring methodology — every score is re-derived by the same automated method as an agent's public evidence changes.
Overview
aws-s3-connector-mcp lets MCP clients connect to AWS S3 buckets to list, upload and read objects in various formats, across public and private buckets and multiple transport modes. Security surface: it uses AWS credentials with object read AND write scope, so over-broad IAM plus prompt injection could exfiltrate or overwrite bucket contents.
