create_backup

Create a backup of files/directories with optional compression

How to control create_backup ↓

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

Medium Risk

This tool creates new backup data (reversible write operation). It does not execute arbitrary commands, delete data, move money, or modify existing files—it only creates copies. The severity is medium because backups could consume significant disk space or be created with sensitive data exposure, but the operation itself is non-destructive and can be undone by removing the backup.

From the tool's definition Tool name 'create_backup' and description 'Create a backup of files/directories with optional compression' indicate data creation and storage operations without permanent deletion or reversal constraints.

Documented attack patterns abuse exactly the kind of access create_backup gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Windows, and nothing reaches the server without passing your rules. This is the rule we recommend for create_backup:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_backup": {
      "limits": [
        {
          "counter": "create_backup_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_backup 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.

  1. Create a free account and register Mcp Windows — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the create_backup tool do? +

Create a backup of files/directories with optional compression. It is categorised as a Write tool in the Mcp Windows MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_backup? +

Register the Mcp Windows MCP server in PolicyLayer and add a rule for create_backup: 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 Mcp Windows. Nothing to install.

What risk level is create_backup? +

create_backup is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_backup? +

Yes. Add a rate_limit block to the create_backup 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 create_backup completely? +

Set action: deny in the PolicyLayer policy for create_backup. 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 create_backup? +

create_backup is provided by the Mcp Windows MCP server (mukul975/mcp-windows-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Mcp Windows tool call.
