list_k8s_resources
AI agents call list_k8s_resources to retrieve information from AWS IoT SiteWise MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries Kubernetes resource information, which is a read operation with no side effects. However, confidence is moderate (0.75) rather than high because the description is empty, leaving some ambiguity about what specific resources are returned and whether sensitive data (e.g., secrets, credentials) might be exposed.
From the tool's definition Tool name 'list_k8s_resources' indicates it retrieves/queries Kubernetes resources without modifying them. The '_list_' prefix is characteristic of read-only operations that enumerate or fetch data.
Attacks that exploit this kind of access
list_k8s_resources. It is categorised as a Read tool in the AWS IoT SiteWise MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS IoT SiteWise MCP Server MCP server in PolicyLayer and add a rule for list_k8s_resources: 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 AWS IoT SiteWise MCP Server. Nothing to install.
list_k8s_resources 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_k8s_resources 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_k8s_resources. 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_k8s_resources is provided by the AWS IoT SiteWise MCP Server MCP server (awslabs.aws-iot-sitewise-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
