MCP Tools Reference: container.googleapis.com

Tool: get_k8s_resource

Gets one or more Kubernetes resources from a cluster. Resources can be filtered by type, name, namespace, and label selectors. Returns the resources in YAML format. This is similar to running kubectl get .

The following sample demonstrate how to use curl to invoke the get_k8s_resource MCP tool.

Fields
parent

string

Required. The cluster, which owns this collection of resources. Format: projects/{project}/locations/{location}/clusters/{cluster}

resourceType

string

Required. The type of resource to retrieve. Kubernetes resource/kind name in singular form, lower case. e.g. "pod", "deployment", "service".

name

string

Optional. The name of the resource to retrieve. If not specified, all resources of the given type are returned.

namespace

string

Optional. The namespace of the resource. If not specified, all namespaces are searched.

labelSelector

string

Optional. A label selector to filter resources.

fieldSelector

string

Optional. A field selector to filter resources.

customColumns

string ( FieldMask format)

Optional. The field mask to specify columns to display. Use a single "*" to get all fields. When both custom_columns and output_format are specified, output_format is ignored.

This is a comma-separated list of fully qualified names of fields. Example: "user.displayName,photo" .

outputFormat

enum ( OutputFormat )

Optional. The output format. One of: (table, wide, yaml, json). If not specified, defaults to table. When both custom_columns and output_format are specified, output_format is ignored.

FieldMask

 { 
 "paths"

Fields
paths[]

string

The set of field mask paths.

Output Schema

Response for retrieving Kubernetes resources.

 "output" 
 : 
 string 
 , 
 "errors" 
 : 
 [ 
 { 
 object (  Status 
 
) 
 } 
 ] 
 } 
Fields
output

string

The output of the command in the requested format. It may contain resources in YAML or JSON format, or a table in plain text, or errors.

errors[]

object ( Status )

Errors encountered during retrieval.

Status

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

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.
