Schema Sieve MCP

A local MCP server for inspecting JSON Schema structures and planning privacy-safe test fixtures. It identifies required paths, nested constraints, unions, arrays, and sensitive fields without validating or scanning for security issues. It supports summarizing types and generating placeholder paths like <string> or <integer> while omitting actual data values.
