Data conversion and parsing

JSON Schema validator for AI agents

Checks JSON against a schema and lists the errors.

utilities.json_schema_validator

What it does

Checks JSON against a schema and lists the errors. It is one of the Data conversion and parsing tools in the Ahura Utilities catalogue: a ready-made MCP tool that an agent calls with a typed input and gets a structured result back, with no library to install and no sandbox to start.

How agents use it

Agents use json schema validator to verify structured output from another agent. Because it is a plain tool call, it slots into a single agent turn or a step in an Ahura Workflow, and large inputs and outputs are passed by reference using a store:// address from Ahura Store.
