yaml_to_toml

Convert a YAML string to TOML format.

Parameters

Parameter	Type	Required	Description
input	string	Yes	YAML string to convert. The top-level value must be a mapping; null values and mixed-type sequences are not allowed.

Response

Field	Type	Description
output	string	The converted TOML string.

Example

{
	"input": "name: Alice\nport: 8080\ndb:\n  host: localhost\n"
}

Result:

{
	"output": "name = \"Alice\"\nport = 8080\n\n[db]\nhost = \"localhost\"\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)
conversion_failed	The YAML is valid but cannot be represented as TOML (e.g. the top-level value is not a mapping, or it contains null or mixed-type sequences).	tool error (isError)
internal_error	An unexpected server error.	protocol error (internal_error)

Notes

• TOML does not support null values. Use yaml_to_json if the YAML may contain nulls.
• Arrays must be homogeneous; mixed-type sequences are not allowed.
• The top-level YAML value must be a mapping; sequences and scalars at the top level are rejected.
