What delete_service_env does on Coolify
AI agents call delete_service_env to permanently remove resources in Coolify, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why delete_service_env is rated Critical
Environment variables are configuration data that, once deleted, cannot be automatically recovered. This is an irreversible operation that modifies application configuration state. While not as severe as deleting an entire service or database, deletion of critical environment variables could break application functionality or expose secrets management issues.
From the tool's definition Tool name 'delete_service_env' explicitly indicates deletion of an environment variable. Description states 'Delete an environment variable from a service.' The word 'Delete' combined with environment variable removal indicates irreversible data destruction.
Attacks that exploit this kind of access
The rule that runs delete_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 delete_service_env, this is the rule to start with:
delete_service_env is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Coolify, apply this rule, and every delete_service_env call is checked against it from then on.
