WHAT IT DOES

What git_checkout_branch does on Ha Nexus Agent

AI agents invoke git_checkout_branch to trigger actions in Ha Nexus Agent. 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_branch is rated High

Checking out a branch changes the working state of a git repository, affecting which code/configuration is active. In a Home Assistant context, switching branches could change the active configuration or codebase, with potentially wide-reaching effects on the smart home system. This is an Execute-level action as it triggers a git operation that modifies the working tree state.

RECOMMENDED RULE

The rule that runs git_checkout_branch safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ha Nexus Agent, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For git_checkout_branch, this is the rule to start with:

git_checkout_branch Rate-limited

git_checkout_branch 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_branch": {
      "limits": [
        {
          "counter": "git_checkout_branch_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 Ha Nexus Agent, apply this rule, and every git_checkout_branch call is checked against it from then on.
