List or retrieve ConfigMaps and parse 5G NF configuration sections.
AI agents call tool_k8s_get_configmaps to retrieve information from Kubernetes MCP Server – 5G Core Edition without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only operations against Kubernetes ConfigMaps. While ConfigMaps may contain sensitive configuration data (credentials, API endpoints, network topology), the tool itself only retrieves and parses existing data. The severity is medium rather than low because ConfigMaps in a 5G core network likely contain security-sensitive information; unauthorized disclosure could enable further attacks.
From the tool's definition Tool description states 'List or retrieve ConfigMaps' — purely retrieval operations with no modification or deletion. The phrase 'parse 5G NF configuration sections' indicates data analysis without side effects.
Attacks that exploit this kind of access
List or retrieve ConfigMaps and parse 5G NF configuration sections. It is categorised as a Read tool in the Kubernetes MCP Server – 5G Core Edition MCP Server, which means it retrieves data without modifying state.
Register the Kubernetes MCP Server – 5G Core Edition MCP server in PolicyLayer and add a rule for tool_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 Kubernetes MCP Server – 5G Core Edition. Nothing to install.
tool_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 tool_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 tool_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.
tool_k8s_get_configmaps is provided by the Kubernetes MCP Server – 5G Core Edition MCP server (sanzco/mcp5g). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
