WHAT IT DOES

What create_private_key does on Coolify

AI agents use create_private_key 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_private_key is rated Medium

Creating SSH private keys is a reversible Write operation (keys can be deleted or rotated), but rated high severity because misuse could generate credentials that compromise infrastructure security. An AI agent creating uncontrolled private keys could enable unauthorized access to systems.

From the tool's definition Tool named 'create_private_key' with description 'Create a new SSH private key.' – this creates and stores cryptographic material.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_private_key Rate-limited

create_private_key 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.
