List ConfigMaps in a namespace
AI agents call k8s_list_configmaps 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 enumerates ConfigMaps, which are configuration data objects in Kubernetes. It performs no side effects, creates no resources, and does not execute code or trigger operations. It is a straightforward read/query operation with minimal risk.
From the tool's definition Tool name contains 'list' and description states 'List ConfigMaps in a namespace' — a query operation that retrieves ConfigMap metadata without modifying or deleting resources.
Attacks that exploit this kind of access
List ConfigMaps 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 k8s_list_configmaps: 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.
k8s_list_configmaps 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 k8s_list_configmaps 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 k8s_list_configmaps. 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.
k8s_list_configmaps is provided by the Kubernetes MCP Server MCP server (mjrestivo16/mcp-kubernetes). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
