Security Report
This MCP server implements a focused, read-only schema comparison tool with strong security controls. Path traversal protections are properly implemented, file size limits prevent DoS, and no sensitive data is exposed. Minor code quality issues (broad error handling, lack of input sanitization on string lengths) and missing request logging are present but do not materially affect security. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.

schema-compatibility-mcp
Schema Compatibility compares bounded JSON type fingerprints. It highlights broad type-count changes without exposing property names, values, or schema text. It is not semantic schema compatibility validation.
Quick start
npm install
npm test
npm start
Use compare_schema_shapes with two JSON files inside SCHEMA_COMPATIBILITY_ROOT.
Limits
This is a shape signal, not semantic schema validation. The response contains aggregate type counts only.
