List Kubernetes deployments in a namespace
AI agents call list-deployments 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 performs no side effects—it only retrieves and lists existing Kubernetes deployment objects. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal; an agent listing deployments gains visibility into cluster state but cannot alter infrastructure or resources. This is a standard informational query operation.
From the tool's definition Tool name 'list-deployments' and description 'List Kubernetes deployments in a namespace' indicate a read-only operation that queries and retrieves deployment information without modifying state.
Attacks that exploit this kind of access
List Kubernetes deployments in a namespace. 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 list-deployments: 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.
list-deployments 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 list-deployments 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 list-deployments. 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.
list-deployments 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.
