RISK

Why update_server is rated Medium

This tool modifies server properties (name, comment, avatar, cloud_init configuration) reversibly without destroying data or executing arbitrary code. It falls under Write category. Severity is medium because misconfigured cloud_init or metadata changes could impact server behavior, but the changes are reversible.

From the tool's definition Tool name 'update_server' and description state it 'updates name, comment, avatar_id or cloud_init' — modifications to server metadata and configuration.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_server safely

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

update_server Rate-limited

update_server 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "update_server": {
      "limits": [
        {
          "counter": "update_server_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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