MCP Tools Reference: dataform.googleapis.com

Tool: create_folder

Create a new Dataform folder in a given Google Cloud project and location.

Folders organize Dataform repositories into a hierarchy. Creating a folder doesn't move any repositories into it. To place a repository inside a folder, set the containing_folder parameter value when using the create_repository tool.

Don't attempt to move an existing repository into a folder using the update_repository tool. Once a repository is created, its containing_folder field can't be modified using MCP tools.

The parent parameter value must be in the format projects/{project_id}/locations/{location}.

The folder.display_name parameter value is required and specifies the folder's user-friendly name.

The following code sample shows how to use curl to call the create_folder MCP tool.

Union field _internal_metadata.

_internal_metadata can be only one of the following:
internalMetadata

string

Output only. All the metadata information that is used internally to serve the resource. For example: timestamps, flags, status fields, etc. The format of this field is a JSON string.

Union field _creator_iam_principal.

_creator_iam_principal can be only one of the following:
creatorIamPrincipal

string

Output only. The IAM principal identifier of the creator of the Folder.

Timestamp

JSON representation 
{
  "seconds": string,
  "nanos": integer
}
Fields
seconds

string (int64 format)

Represents seconds of UTC time since Unix epoch 1970-01-01T00:00:00Z. Must be between -62135596800 and 253402300799 inclusive (which corresponds to 0001-01-01T00:00:00Z to 9999-12-31T23:59:59Z).
nanos

integer

Non-negative fractions of a second at nanosecond resolution. This field is the nanosecond portion of the duration, not an alternative to seconds. Negative second values with fractions must still have non-negative nanos values that count forward in time. Must be between 0 and 999,999,999 inclusive.

Output Schema

Tool Annotations

Tool annotations are sent to MCP clients to describe the basic risk of a given tool. Most clients treat these hints as untrusted, but they can be used to decide when a confirmation prompt might be sent to a user.

Along with the title string, the following boolean hints are defined as follows:

  • readOnlyHint: If true, the tool doesn't modify its environment. Default: false.
  • destructiveHint: If true, then the tool can perform destructive actions. If false, then the tool can only perform additive actions. Default: true.
  • idempotentHint: If true, then calling the tool repeatedly with the same arguments will have no additional effect on its environment. Default: false.
  • openWorldHint: If true, then the tool can interact with an 'open world' of external entities. If false, then the tool can only interact with internal entities. For example, a web search tool would be open world, while a memory tool would not be open world.

Destructive Hint: ❌ | Idempotent Hint: ❌ | Read Only Hint: ❌ | Open World Hint: ❌
