(2) The target codebase enforces strict TypeScript and raw JSON.parse is insufficient. (3) You want Auto-JSDoc typedef blocks and z.brand() phantom types generated in a single deterministic call. DO NOT USE WHEN: the source is a TypeScript type definition — use ts-to-zod for that path. Do not use when the input is already a JSON Schema document. OVER ALTERNATIVES: prefer this over quicktype (larger dependency, no branded types) and zod-from-json (no JSDoc, no strict mode toggle).","mcpDescription":"Converts a JSON object or string into a typed Zod schema. USE WHEN: you need a runtime-safe schema from untrusted JSON, want Auto-JSDoc typedefs generated automatically, or need branded ID types for phantom-type safety. INPUT: JSON value plus a schemaName and strategy flags. OUTPUT: Zod schema source code, imports, optional JSDoc block, and inferred TypeScript types.

It provides runtime safety and static type inference via z.infer<>."},{"question":"What are branded types?","answer":"Branded types (z.brand()) add a phantom type tag to a string, making it impossible to accidentally assign a plain string where a UserId is expected — even though they're the same runtime value."},{"question":"Which date strategy should I choose?","answer":"\"string\" keeps dates as validated ISO strings. \"coerce\" parses them into JavaScript Date objects. \"pipe\" validates the string format first, then coerces — the safest option for untrusted input."},{"question":"Does this work with nested JSON?","answer":"Yes. Nested objects generate nested z.object() calls at any depth. Arrays generate z.array() using the first element's type as the item schema."},{"question":"Can I use this tool via the MCP API?","answer":"Yes. The tool is registered on the obfus.link MCP server at https://obfus.link/mcp. Call it from any MCP-compatible agent with a Shared Payment Token.
