WHAT IT DOES

What pip-list does on Build

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

RISK

Why pip-list is rated Low

This tool performs a read-only operation that queries the Python package environment and returns data. It has no side effects—it does not install, modify, or remove packages. It simply retrieves and structures existing information about installed dependencies. This is a low-severity informational tool suitable for inventory or dependency auditing.

From the tool's definition Tool name 'pip-list' and description 'Runs pip list and returns a structured list of installed packages' indicate it retrieves package information without modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pip-list safely

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

pip-list Allowed

pip-list 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": {
    "pip-list": {}
  }
}

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

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