WHAT IT DOES

What github_star_repo does on Github

AI agents use github_star_repo to create or update resources in Github, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Github environment.

RISK

Why github_star_repo is rated Medium

Starring a repository is a reversible write action that modifies the user's starred list on GitHub. It creates a social/bookmarking association but does not delete data, execute code, or involve financial transactions. It can be undone by unstarring. Blast radius is minimal — it only affects the authenticated user's public profile visibility.

RECOMMENDED RULE

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

github_star_repo Rate-limited

github_star_repo stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "github_star_repo": {
      "limits": [
        {
          "counter": "github_star_repo_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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