Tool: `get_k8s_version`

Retrieves Kubernetes client and server versions for a given cluster. This is similar to running kubectl version .

The following sample demonstrate how to use curl to invoke the get_k8s_version MCP tool.

Curl Request
curl --location 'https://container.googleapis.com/mcp' \ --header 'content-type: application/json' \ --header 'accept: application/json, text/event-stream' \ --data '{ "method": "tools/call", "params": { "name": "get_k8s_version", "arguments": { // provide these details according to the tool' s MCP specification } } , "jsonrpc" : "2.0" , "id" : 1 } '

Input Schema

KubeVersionRequest is the request message for retrieving Kubernetes server versions.

GetK8SVersionRequest

JSON representation
{ "parent" : string }

Fields

Fields
`parent`	`string` Required. The cluster to get version information from, in the format `projects//locations//clusters/*` .

parent

string

Required. The cluster to get version information from, in the format projects/*/locations/*/clusters/* .

Output Schema

KubeVersionResponse is the response message for retrieving Kubernetes server version.

GetK8SVersionResponse

JSON representation
{ "serverVersion" : string , "errors" : [ { object ( `Status` ) } ] }

Fields

Fields
`serverVersion`	`string` The server version.
`errors[]`	`object ( Status )` Errors encountered during version retrieval.

serverVersion

string

The server version.

errors[]

object ( Status )

Errors encountered during version retrieval.

Status

JSON representation
{ "code" : integer , "message" : string , "details" : [ { "@type" : string , field1 : ... , ... } ] }

Fields

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" }` .

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" } .

Any

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

Fields

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.

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.

value

string ( bytes format)

Holds a Protobuf serialization of the type described by type_url.

A base64-encoded string.
