WHAT IT DOES

What list_tags does on GitHub

AI agents call list_tags 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_tags is rated Low

This tool retrieves existing tags from a GitHub repository with no side effects. It performs a simple enumeration of existing data, which is the definition of a Read category tool. Low severity because listing tags has no blast radius—an AI cannot misuse this to cause harm.

From the tool's definition Tool name 'list_tags' and description 'List tags' indicate a query operation that retrieves tag information without modification. 'List' is a classic Read operation pattern.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_tags 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_tags, this is the rule to start with:

list_tags Allowed

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

policy.json

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

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_tags call is checked against it from then on.
