get-contexts · Kubernetes MCP Server MCP: Risk & Policy

WHAT IT DOES

What get-contexts does on Kubernetes MCP Server

AI agents call get-contexts to retrieve information from Kubernetes MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why get-contexts needs a policy

This tool queries and returns existing Kubernetes context configuration data. It performs a passive read operation (list) with no capacity to modify, delete, or execute operations. While it reveals cluster topology information that could inform reconnaissance, the tool itself has no blast radius when invoked by an AI agent—it cannot cause harm, only return data.

From the tool's definition Tool name 'get-contexts' and description 'List all kubectl contexts' indicate retrieval of cluster context information with no modification or side effects.

Questions about get-contexts

What does the get-contexts tool do? +

List all kubectl contexts. It is categorised as a Read tool in the Kubernetes MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get-contexts? +

Register the Kubernetes MCP Server MCP server in PolicyLayer and add a rule for get-contexts: 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. Nothing to install.

What risk level is get-contexts? +

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

Can I rate-limit get-contexts? +

Yes. Add a rate_limit block to the get-contexts 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.

How do I block get-contexts completely? +

Set action: deny in the PolicyLayer policy for get-contexts. 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 get-contexts? +

get-contexts is provided by the Kubernetes MCP Server MCP server (thekaranpargaie/kube-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
