WHAT IT DOES

What git_list_repositories does on GitHub

AI agents call git_list_repositories 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 git_list_repositories is rated Low

This tool performs a query operation to enumerate or retrieve repository metadata. It has no side effects—it neither modifies, deletes, nor executes any code. The blast radius of misuse is minimal, as an AI agent could at worst enumerate repositories to which it has access, without causing damage.

From the tool's definition Tool name 'git_list_repositories' and description 'Git list repositories' indicate data retrieval without modification. The verb 'list' is a read operation that queries and returns repository information.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

git_list_repositories Allowed

git_list_repositories 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": {
    "git_list_repositories": {}
  }
}

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 git_list_repositories call is checked against it from then on.
