What describe_k8s_resource does on Mcp
AI agents call describe_k8s_resource to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
name | string | — | Optional. The name of the resource. |
parent | string | Yes | Required. The parent cluster. |

Why describe_k8s_resource is rated Low
The `describe_k8s_resource` tool performs a read-only query operation to retrieve and display details about Kubernetes resources. The `kubectl describe` command it mirrors is a standard inspection utility that has no side effects—it only fetches and presents existing resource information. There is no data modification, deletion, code execution, or financial impact.
From the tool's definition Tool description states 'Shows the details of a specific Kubernetes resource' and is 'similar to running `kubectl describe`', which is a read-only inspection command that retrieves and displays resource metadata without modifying state.
Attacks that exploit this kind of access
The rule that runs describe_k8s_resource safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For describe_k8s_resource, this is the rule to start with:
describe_k8s_resource is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp, apply this rule, and every describe_k8s_resource call is checked against it from then on.
Questions about describe_k8s_resource
Shows the details of a specific Kubernetes resource. This is similar to running kubectl describe. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
describe_k8s_resource accepts 5 parameters: name, parent, namespace, resourceType, labelSelector. Required: parent, resourceType. The full parameter table on this page comes from the server's own tool schema.
Register the MCP server in PolicyLayer and add a rule for describe_k8s_resource: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp. Nothing to install.
describe_k8s_resource is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the describe_k8s_resource rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for describe_k8s_resource. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
describe_k8s_resource is provided by the MCP server (https://container.googleapis.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
