Inspector Chrome Extension

The Inspector Chrome Extension tool parses and analyzes a Chrome extension’s manifest.json and related scripts to generate a structured risk assessment. It identifies permission scopes, host_permissions exposure, MV3 compatibility, and potential privacy implications. The tool aggregates findings into a risk_score and categorized findings, enabling developers, security engineers, and product owners to understand where an extension may be over-privileged or non-compliant. It conceptually maps each permission to its likely impact and suggests mitigations such as permission minimization and scope narrowing. Core features include manifest parsing, permission mapping, privacy impact estimation, and exportable reports. Use cases include pre-release reviews, security audits of published extensions, and policy compliance checks in teams that manage browser extensions. A unique value proposition is the combination of manifest-level analysis with a structured risk model and exportable documentation suitable for compliance artifacts. The tool is designed for speed, operating on a package or manifest input, and it provides actionable recommendations in addition to a quantitative risk score. Outputs support downstream processes like threat modeling, code reviews, and governance documentation. Users benefit from standardized risk metrics and repeatable assessments across multiple extensions, reducing time to secure shipping and improving overall extension quality.
