THE RISK

Low Risk

Why stream_info needs a policy

The tool retrieves or queries information about a stream without creating, modifying, deleting, or executing operations. This is a passive data retrieval action with minimal blast radius if misused by an AI agent—at most, an attacker could enumerate stream details to gather reconnaissance information.

From the tool's definition Tool name 'stream_info' and description 'Get information about stream' indicate a retrieval operation with no modification or execution of external commands.

Documented attack patterns abuse exactly the kind of access stream_info gives an agent:

POLICY

How to control stream_info

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon EKS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for stream_info:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "stream_info": {}
  }
}

stream_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Amazon EKS MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about stream_info

What does the stream_info tool do? +

Get information about stream. It is categorised as a Read tool in the Amazon EKS MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on stream_info? +

Register the Amazon EKS MCP Server MCP server in PolicyLayer and add a rule for stream_info: 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 Amazon EKS MCP Server. Nothing to install.

What risk level is stream_info? +

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

Can I rate-limit stream_info? +

Yes. Add a rate_limit block to the stream_info 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 stream_info completely? +

Set action: deny in the PolicyLayer policy for stream_info. 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 stream_info? +

stream_info is provided by the Amazon EKS MCP Server MCP server (awslabs.eks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Amazon EKS MCP Server tool call.

Start from Amazon EKS MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
