AI agents use enable_backups to create or update resources in Linode MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Linode MCP Server environment.
This tool modifies instance configuration by enabling a backup feature. It is reversible (backups can be disabled), creates/modifies data retention settings, and does not delete, execute arbitrary code, or move money. It falls under Write category.
From the tool's definition Tool name 'enable_backups' and description 'Enable backups for a Linode instance' indicate creation or modification of backup configuration for a compute instance.
Documented attack patterns abuse exactly the kind of access enable_backups gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Linode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for enable_backups:
{
"version": "1",
"default": "deny",
"tools": {
"enable_backups": {
"limits": [
{
"counter": "enable_backups_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}enable_backups 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.
Free to start. No card required.
Enable backups for a Linode instance. It is categorised as a Write tool in the Linode MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Linode MCP Server MCP server in PolicyLayer and add a rule for enable_backups: 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 Linode MCP Server. Nothing to install.
enable_backups is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the enable_backups 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.
Set action: deny in the PolicyLayer policy for enable_backups. 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.
enable_backups is provided by the Linode MCP Server MCP server (takashito/linode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Linode MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
