WHAT IT DOES

What list-package does on Npm

AI agents call list-package 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 list-package is rated Low

The tool performs a read-only operation (dotnet list package) that enumerates installed packages and their versions. There are no modifications to the project state, no code execution, and no irreversible actions. The output is informational only, making this a straightforward Read category risk.

From the tool's definition Tool description states it 'returns structured NuGet package listings per project and framework' — a query operation that retrieves package metadata without modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list-package 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 list-package, this is the rule to start with:

list-package Allowed

list-package 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": {
    "list-package": {}
  }
}

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 list-package call is checked against it from then on.
