Parse yaml
Pass the content and direction ("yaml-to-json" or "json-to-yaml"). This engine uses the yaml package (30M+ weekly downloads) which is more robust than js-yaml and passes the official YAML test suite. Converts YAML to JSON and vice versa. Supports YAML 1.1/1.2 with comment preservation. Essential for Kubernetes, GitHub Actions, Docker Compose, and Ansible configs

Preview access · not provider authentication
The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of yaml, so you can see the experience inside your AI.
It does not authenticate your account with yaml. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ
Questions yaml owners ask.
- 01
Why is YAML dangerous for AI agents?
YAML is whitespace-sensitive. A single misplaced indent changes the entire structure silently. no error, just wrong behavior. AI models frequently hallucinate incorrect indentation, lose anchor references, and add trailing spaces. This engine validates against the real spec.
- 02
Does it handle YAML anchors and merge keys?
Yes. Full support for anchors (&default), aliases (*default), and merge keys (<<). the features that trip up every other parser and every AI model.
- 03
Can it parse multi-document YAML files?
Yes. Files separated by --- markers are fully supported. Each document is parsed independently and returned as a separate JSON object.
