AI agents call get_configmap to retrieve information from K8s without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries Kubernetes ConfigMap resources. It performs no side effects, creates no resources, executes no code, deletes nothing, and involves no financial operations. It is a pure data retrieval operation against existing Kubernetes state, making it a Read category tool with low severity.
From the tool's definition Tool name 'get_configmap' and description 'Get a ConfigMap's metadata and data contents' indicate retrieval without modification. The verb 'Get' and action of retrieving metadata and data are characteristic of read-only operations.
Attacks that exploit this kind of access
Get a ConfigMap's metadata and data contents. It is categorised as a Read tool in the K8s MCP Server, which means it retrieves data without modifying state.
Register the K8s MCP server in PolicyLayer and add a rule for get_configmap: 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. Nothing to install.
get_configmap 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 get_configmap 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 get_configmap. 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.
get_configmap is provided by the K8s MCP server (jingyanjiang/k8s-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
