JSON Schema Strict Validator Connector for AI agents.

Q: Can I use this to check for breaking changes in my API?

Yes, by using the evaluatecompatibility tool, you can compare an old schema against a new one to identify removed required fields or properties that might break your integration.

Q: How do I validate environment variables?

You can use the verifyintegrity tool. Pass a string of key-value pairs (like PORT=8080) and an array of constraints to ensure each key matches its expected type.

Before you connect

Questions about JSON Schema Strict Validator.

The practical details behind the request, access and result.

What does 'strict mode' mean in this validator?

Strict mode means that if a schema does not explicitly define additionalProperties, the validator treats it as false. Any property found in the JSON instance that is not declared in the schema will trigger an error.

Can I use this to check for breaking changes in my API?

Yes, by using the evaluate_compatibility capability, you can compare an old schema against a new one to identify removed required fields or properties that might break your integration.

How do I validate environment variables?

You can use the verify_integrity capability. Pass a string of key-value pairs (like PORT=8080) and an array of constraints to ensure each key matches its expected type.
