yaml_to_json

Convert a YAML string to pretty-printed JSON.

Parameters

Parameter	Type	Required	Description
input	string	Yes	YAML string to convert.

Response

Field	Type	Description
output	string	The converted pretty-printed JSON string.

Example

{
	"input": "name: Alice\nage: 30\nactive: true\n"
}

Result:

{
	"output": "{\n  \"name\": \"Alice\",\n  \"age\": 30,\n  \"active\": true\n}"
}

Errors

Each failure carries a precise code in the response. Argument-schema and server errors are JSON-RPC protocol errors; a rejected value is returned as a tool result with isError: true (so the agent can read the code and self-correct).

Code	When	Delivered as
invalid_arguments	input is missing or not a string.	protocol error (invalid_params)
invalid_yaml	The input string is not valid YAML.	tool error (isError)
internal_error	An unexpected server error.	protocol error (internal_error)

Notes

• YAML timestamps and other non-JSON types are converted to strings.
• Multi-document YAML (separated by ---) is not supported and will cause an error.
