WHAT IT DOES

What list does on Github

AI agents call list to retrieve information from Github 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 is rated Low

This tool queries and retrieves information about Go packages/modules in a structured format. It performs no write, delete, execute, or financial operations. The action is purely informational and read-only, making it a Read category tool with low severity.

From the tool's definition Tool description states it 'Lists Go packages or modules and returns structured information.' The verb 'lists' indicates data retrieval without modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list safely

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

list Allowed

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": {
    "list": {}
  }
}

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

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