WHAT IT DOES

What vagrant does on Docker

AI agents invoke vagrant to trigger actions in Docker. 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 vagrant is rated High

This tool can start (up), stop (halt), and destroy Vagrant VMs. While 'destroy' is listed, the tool is primarily an execution/management interface for VMs. Destroy is included, making this at minimum Execute and potentially Destructive. Since the tool bundles both operational and destructive actions, the most severe applicable category is Destructive — 'destroy' irreversibly removes a VM and its associated state.

RECOMMENDED RULE

The rule that runs vagrant safely

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

vagrant Rate-limited

vagrant 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": {
    "vagrant": {
      "limits": [
        {
          "counter": "vagrant_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 Docker, apply this rule, and every vagrant call is checked against it from then on.

FAQ

Questions about vagrant

What does the vagrant tool do? +

Manages Vagrant VMs: status, global-status, up, halt, destroy. It is categorised as a Execute tool in the Docker MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on vagrant? +

Register the Docker MCP server in PolicyLayer and add a rule for vagrant: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Docker. Nothing to install.

What risk level is vagrant? +

vagrant is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit vagrant? +

Yes. Add a rate_limit block to the vagrant rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block vagrant completely? +

Set action: deny in the PolicyLayer policy for vagrant. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides vagrant? +

vagrant is provided by the Docker MCP server (@paretools/docker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
