WHAT IT DOES

What list_label does on GitHub

AI agents call list_label 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_label is rated Low

This tool retrieves and enumerates existing labels from a GitHub repository. It does not create, modify, delete, or execute any operations; it only queries and returns information. This is a straightforward Read operation with minimal risk if misused by an AI agent.

From the tool's definition Tool name is 'list_label' and description states 'List labels from a repository' — this is a data retrieval operation with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_label 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_label, this is the rule to start with:

list_label Allowed

list_label 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_label": {}
  }
}

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_label call is checked against it from then on.
