Low Risk

resources_list

List Kubernetes resources and objects in the current cluster by providing their apiVersion and kind and optionally the namespace and label selector

Part of the Kubernetes MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call resources_list to retrieve information from Kubernetes without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though resources_list only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the resources_list tool do? +

List Kubernetes resources and objects in the current cluster by providing their apiVersion and kind and optionally the namespace and label selector. It is categorised as a Read tool in the Kubernetes MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on resources_list? +

Add a rule in your Intercept YAML policy under the tools section for resources_list. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Kubernetes MCP server.

What risk level is resources_list? +

resources_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit resources_list? +

Yes. Add a rate_limit block to the resources_list rule in your Intercept 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.

How do I block resources_list completely? +

Set action: deny in the Intercept policy for resources_list. 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.

What MCP server provides resources_list? +

resources_list is provided by the Kubernetes MCP server (kubernetes-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
