JSONBuddy Data Validator
@Clemens Uhlenhut
This project provides an MCP-compatible interface for the JSONBuddy Core API, enabling JSON validation against schemas via a secure HTTP-based service. The server exposes two endpoints (`/validator/validate` and `/validator/validate-simple`) for flexible schema validation scenarios. MCP clients and AI agents can integrate this API using the included `mcp.json` definition and standard API key authentication.
Overview
JSONBuddy Core API
The JSONBuddy Core API provides server-side validation of JSON data against JSON Schema definitions. Currently, it offers two endpoints:
- Simple validation for quick checks with plain JSON strings.
- Advanced validation supporting structured input.
This MCP Server enables AI agents, workflows, and automation tools to ensure the correctness of JSON data in real-time. The service is fast, secure, and requires an API key for authenticated use.
