GenPark JSON Schema Contract Validator

A local, zero-dependency JSON Schema subset validator that lets an assistant check structured outputs against a contract.

What you can do

• Validate JSON documents against a supported subset of JSON Schema.
• Check that LLM-generated structured output conforms to an expected contract.
• Report conformance results so the assistant can correct or reject malformed data.
• No tool list is published, so exact operations are not documented.

When to use it

Useful when an assistant produces structured JSON that must match a schema, and you want a local check before the data is accepted or passed downstream.

Requirements

Runs as a local process on the user's machine, distributed as an MCPB package for desktop clients. No authentication, environment variables or headers are declared.
