Describe details of a Kubernetes secret
AI agents call describe-secret to retrieve information from Kubernetes MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about Kubernetes secrets. While classified as Read (no side effects), the severity is elevated to medium because secrets in Kubernetes typically contain sensitive credentials (API keys, passwords, tokens). Unauthorized exposure of secret contents poses a confidentiality risk, though the tool itself performs no destructive or write operations.
From the tool's definition Tool name 'describe-secret' and description 'Describe details of a Kubernetes secret' indicate retrieval of secret data without modification. The verb 'describe' is a read operation.
Attacks that exploit this kind of access
Describe details of a Kubernetes secret. It is categorised as a Read tool in the Kubernetes MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kubernetes MCP Server MCP server in PolicyLayer and add a rule for describe-secret: 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 Kubernetes MCP Server. Nothing to install.
describe-secret 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-secret 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-secret. 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-secret is provided by the Kubernetes MCP Server MCP server (thekaranpargaie/kube-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
