Lists ConfigMaps in a namespace
AI agents call k8s.get_configmaps to retrieve information from K8s Mcp Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries Kubernetes ConfigMaps (configuration data) without modifying, deleting, or executing anything. It is a straightforward data retrieval operation consistent with the server's stated read-only purpose. The blast radius of misuse is minimal—an attacker gains visibility into application configuration but cannot alter systems or access secrets beyond what the tool exposes.
From the tool's definition Tool name 'get_configmaps' and description 'Lists ConfigMaps in a namespace' indicate a read-only retrieval operation. Server is explicitly described as 'read-only' and enables developers to 'inspect' and 'view' without write/delete capabilities.
Attacks that exploit this kind of access
Lists ConfigMaps in a namespace. It is categorised as a Read tool in the K8s Mcp Assistant MCP Server, which means it retrieves data without modifying state.
Register the K8s Mcp Assistant MCP server in PolicyLayer and add a rule for k8s.get_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 K8s Mcp Assistant. Nothing to install.
k8s.get_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.get_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.get_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.get_configmaps is provided by the K8s Mcp Assistant MCP server (nicolasmosquerar/k8s-mcp-assistant). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
