Json To Typescript

Data REST API MCP

Generate TypeScript interfaces or type aliases from a JSON sample. Nested objects become named declarations (or inline object types), arrays infer element unions, and identical shapes are declared once.

This page documents the HTTP endpoint POST /api/tools/json-to-typescript/execute. See the MCP reference →
