Security Report
Excellent security posture. This is a local-first Unicode analysis tool with no network calls, no authentication requirements, and well-scoped permissions. Code is clean, input validation is present via Zod schemas, and the server appropriately warns users that its heuristic analysis is not a complete security implementation. No security vulnerabilities detected. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.

unicode-security-mcp
A local-first MCP server for catching Unicode tricks before they become confusing bug reports or security incidents.
Tools
analyze_text: detect confusable characters, invisible controls, mixed scripts, and a heuristic risk level.compare_identifiers: compare two names through a small confusable skeleton.get_skeleton: normalize one identifier for local comparison.
The server never sends input to a network service. It is a review aid, not a complete Unicode Security Mechanisms implementation. The bundled mappings are intentionally conservative and should not replace platform IDNA, normalization, font, or language-specific security review.
Run
npm install
npm run build
node dist/index.js
