WHAT IT DOES

What update_server does on Coolify

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

RISK

Why update_server is rated Medium

The tool modifies existing server data, which is a Write-category operation. Severity is high because server configuration updates could affect deployment environments, application hosting, and infrastructure stability. Confidence is high given the clear intent of the 'update' verb and the infrastructure management context of the Coolify platform.

From the tool's definition Tool name 'update_server' and description 'Update an existing server by UUID' indicate modification of server configuration. This is a reversible write operation that modifies infrastructure settings.

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 Coolify, 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.

}

LIMIT THIS TOOL → Instant setup, no code required.

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