WHAT IT DOES

What git_checkout does on GitHub

AI agents invoke git_checkout to trigger actions in GitHub. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why git_checkout is rated High

Git checkout switches branches or restores working tree files, which is an operation that triggers external git operations and can alter repository state. The description is minimal/uninformative, but the tool name clearly references a git operation that changes the working tree or branch context. This could affect code being built/deployed, making it high severity if misused by an AI agent.

From the tool's definition Tool name 'git_checkout' and description 'Git checkout'

RECOMMENDED RULE

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

git_checkout Rate-limited

git_checkout stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "git_checkout": {
      "limits": [
        {
          "counter": "git_checkout_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

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