## Why github_unstar_repo is rated Medium

Unstarring a repository is a reversible write operation that modifies the user's GitHub profile state by removing a star. It does not create permanent artifacts, delete data, execute code, or have financial implications. The impact is limited to the user's own interaction metadata and is easily reversible by starring again. Severity is low due to minimal blast radius and reversibility.

From the tool's own definition: "Tool name 'github_unstar_repo' and description 'Unstar a repo' indicate modification of user state (removing a star from a repository)."

## Use case

AI agents use github_unstar_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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Github:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "github_unstar_repo": {
      "limits": [
        {

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
