WHAT IT DOES

What create_service_env does on Coolify

AI agents use create_service_env 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 create_service_env is rated Medium

This tool creates new environment variables, which are reversible configuration changes. It modifies service configuration state but does not execute arbitrary code, delete data, or move money. The severity is medium because misconfigured environment variables could expose secrets or cause service misconfigurations if an AI agent sets inappropriate values, but the change can be undone by deletion or update.

From the tool's definition Tool name 'create_service_env' and description 'Create an environment variable for a service' indicate the tool creates (writes) configuration data for a service.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_service_env 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 create_service_env, this is the rule to start with:

create_service_env Rate-limited

create_service_env 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.

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