    MCP Tools Reference: bigtableadmin.googleapis.com

    Tool: create_instance

    Create a new instance in the specified project. The request requires project_id, instance_id, display_name, and at least one cluster. Each cluster must specify its zone (e.g. us-central1-a). Example: { "project_id": "my-project", "instance_id": "my-instance", "display_name": "This is my instance", "clusters": [ { "zone": "us-central1-a", "serve_nodes": 3, "default_storage_type": "SSD" } ] }

    The following sample demonstrate how to use curl to invoke the create_instance MCP tool.

    Fields
    projectId

    string

    Required. The project ID (e.g., "my-project"). If not known from the context, the Agent should attempt to get the current project ID from the gcloud config by running gcloud config get-value project . If the attempt fails, prompt the user for the project ID.
    instanceId

    string

    Required. The ID to be used when referring to the new instance within its project, e.g., just myinstance rather than projects/myproject/instances/myinstance .
    displayName

    string

    Required. The descriptive name for this instance as it appears in UIs.
    clusters[]

    object ( Cluster )

    Required. Clusters to be created within the instance. At least one cluster must be specified.

    Fields
    clusterId

    string

    Optional. The ID of the cluster, e.g., just mycluster rather than projects/myproject/instances/myinstance/clusters/mycluster . The tool mapping will provide a default if this is not specified (e.g., {instance_id}-c{index} ).
    zone

    string

    Required. The zone where the cluster will be located. e.g., us-central1-a .
    serveNodesCount

    integer

    Optional. The number of nodes to serve. If not specified, the tool mapping will default to 1.
    defaultStorageType

    enum ( StorageType )

    Optional. The default storage type for the cluster, e.g., SSD, HDD. If not specified, the tool mapping will default to SSD.

    Output Schema

    This resource represents a long-running operation that is the result of a network API call.

. 
 }
    Fields
    name

    string

    The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name should be a resource name ending with operations/{unique_id} .

    metadata

    object

    Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.

    An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" } .

    done

    boolean

    If the value is false , it means the operation is still in progress. If true , the operation is completed, and either error or response is available.

    Union field result . The operation result, which can be either an error or a valid response . If done == false , neither error nor response is set. If done == true , exactly one of error or response can be set. Some services might not provide the result. result can be only one of the following:
    error

    object ( Status )

    The error result of the operation in case of failure or cancellation.

    response

    object

    The normal, successful response of the operation. If the original method returns no data on success, such as Delete , the response is google.protobuf.Empty . If the original method is standard Get / Create / Update , the response should be the resource. For other methods, the response should have the type XxxResponse , where Xxx is the original method name. For example, if the original method name is TakeSnapshot() , the inferred response type is TakeSnapshotResponse .

    An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" } .

    Any

    JSON representation 
     { 
 "typeUrl" 
 : 
 string 
 , 
 "value" 
 : 
 string 
 }
    Fields
    typeUrl

    string

    Identifies the type of the serialized Protobuf message with a URI reference consisting of a prefix ending in a slash and the fully-qualified type name.

    Example: type.googleapis.com/google.protobuf.StringValue

    This string must contain at least one / character, and the content after the last / must be the fully-qualified name of the type in canonical form, without a leading dot. Do not write a scheme on these URI references so that clients do not attempt to contact them.

    The prefix is arbitrary and Protobuf implementations are expected to simply strip off everything up to and including the last / to identify the type. type.googleapis.com/ is a common default prefix that some legacy implementations require. This prefix does not indicate the origin of the type, and URIs containing it are not expected to respond to any requests.

    All type URL strings must be legal URI references with the additional restriction (for the text format) that the content of the reference must consist only of alphanumeric characters, percent-encoded escapes, and characters in the following set (not including the outer backticks): /-.~_!$&()*+,;= . Despite our allowing percent encodings, implementations should not unescape them to prevent confusion with existing parsers. For example, type.googleapis.com%2FFoo should be rejected.

    In the original design of Any , the possibility of launching a type resolution service at these type URLs was considered but Protobuf never implemented one and considers contacting these URLs to be problematic and a potential security issue. Do not attempt to contact type URLs.
    value

    string ( bytes format)

    Holds a Protobuf serialization of the type described by type_url.

    A base64-encoded string.

    Fields
    code

    integer

    The status code, which should be an enum value of google.rpc.Code .
    message

    string

    A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.
    details[]

    object

    A list of messages that carry the error details. There is a common set of message types for APIs to use.

    An object containing fields of an arbitrary type. An additional field "@type" contains a URI identifying the type. Example: { "id": 1234, "@type": "types.example.com/standard/id" } .
