MCP Tools Reference: bigtableadmin.googleapis.com

Tool: list_instances

List information about instances in a project. The request requires the 'parent' field to be set in the format 'projects/{project}'. Example: { "parent": "projects/my-project" }

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

Curl Request 
                  
curl --location 'https://bigtableadmin.googleapis.com/mcp' \
--header 'content-type: application/json' \
--header 'accept: application/json, text/event-stream' \
--data '{
  "method": "tools/call",
  "params": {
    "name": "list_instances",
    "arguments": {
      // provide these details according to the tool's MCP specification
    }
  },
  "jsonrpc": "2.0",
  "id": 1
}'

ListInstancesRequest

JSON representation 
{
  "parent": string,
  "pageToken": string
}
Fields
parent

string

Required. The unique name of the project for which a list of instances is requested. Values are of the form projects/{project}.

ListInstancesResponse

JSON representation 
{
  "instances": [
    {
      object (Instance)
    }
  ],
  "failedLocations": [
    string
  ],
  "nextPageToken": string
}
Fields
instances[]

object (Instance)

The list of requested instances.
failedLocations[]

string

Locations from which Instance information could not be retrieved, due to an outage or some other transient condition. Instances whose Clusters are all in one of the failed locations may be missing from instances, and Instances with at least one Cluster in a failed location may only have partial information returned. Values are of the form projects/<project>/locations/<zone_id>
nextPageToken
(deprecated)

string

DEPRECATED: This field is unused and ignored.

  // Union field _satisfies_pzs can be only one of the following:

  // Union field _satisfies_pzi can be only one of the following:
  "satisfiesPzi": boolean
  // End of list of possible types for union field _satisfies_pzi.
}
Fields
name

string

The unique name of the instance. Values are of the form projects/{project}/instances/[a-z][a-z0-9\\-]+[a-z0-9].
displayName

string

Required. The descriptive name for this instance as it appears in UIs. Can be changed at any time, but should be kept globally unique to avoid confusion.
state

enum (State)

Output only. The current state of the instance.
type

enum (Type)

The type of the instance. Defaults to PRODUCTION.
labels

map (key: string, value: string)

Labels are a flexible and lightweight mechanism for organizing cloud resources into groups that reflect a customer's organizational needs and deployment strategies. They can be used to filter resources and aggregate metrics.

  • Label keys must be between 1 and 63 characters long and must conform to the regular expression: [\p{Ll}\p{Lo}][\p{Ll}\p{Lo}\p{N}_-]{0,62}.
  • Label values must be between 0 and 63 characters long and must conform to the regular expression: [\p{Ll}\p{Lo}\p{N}_-]{0,63}.
  • No more than 64 labels can be associated with a given resource.
  • Keys and values must both be under 128 bytes.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
createTime

string (Timestamp format)

Output only. A commit timestamp representing when this Instance was created. For instances created before this field was added (August 2021), this value is seconds: 0, nanos: 1.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
tags

map (key: string, value: string)

Optional. Input only. Immutable. Tag keys/values directly bound to this resource. For example: - "123/environment": "production", - "123/costCenter": "marketing"

Tags and Labels (above) are both used to bind metadata to resources, with different use-cases. See https://cloud.google.com/resource-manager/docs/tags/tags-overview for an in-depth overview on the difference between tags and labels.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

Union field _satisfies_pzs.

_satisfies_pzs can be only one of the following:
satisfiesPzs

boolean

Output only. Reserved for future use.

Union field _satisfies_pzi.

_satisfies_pzi can be only one of the following:
satisfiesPzi

boolean

Output only. Reserved for future use.

Timestamp

JSON representation 
{
  "seconds": string,

}
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.
