WHAT IT DOES

What stats does on Npm

AI agents call stats to retrieve information from Npm without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why stats is rated Low

This tool only retrieves and reports system metrics about container resources. It performs a passive read-only query with no side effects, no code execution, no data modification, and no destructive operations. The low severity reflects minimal risk even if misused by an agent—gathering resource metrics does not compromise system integrity or enable harmful actions.

From the tool's definition Tool returns resource usage statistics (CPU, memory, network/block I/O, PIDs) as structured data with no modification or execution capability.

RECOMMENDED RULE

The rule that runs stats safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Npm, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For stats, this is the rule to start with:

stats Allowed

stats is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Npm, apply this rule, and every stats call is checked against it from then on.

FAQ

Questions about stats

What does the stats tool do? +

Returns a snapshot of container resource usage (CPU, memory, network/block I/O, PIDs) as structured data. It is categorised as a Read tool in the Npm MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on stats? +

Register the Npm MCP server in PolicyLayer and add a rule for stats: 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 Npm. Nothing to install.

What risk level is stats? +

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

Can I rate-limit stats? +

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

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

stats is provided by the Npm MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
