create_application · Coolify MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_application does on Coolify MCP Server

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

WHY IT NEEDS A POLICY

Why create_application needs a policy

This tool creates new application resources, which is a Write operation (reversible modification of data/state). Severity is high because creating applications could involve provisioning compute resources, establishing network configurations, and triggering deployments—misuse could exhaust resources, create security vulnerabilities, or introduce malicious services into the infrastructure.

From the tool's definition Tool name 'create_application' and description 'Create a new application' indicate data creation. In the context of Coolify managing 'applications, databases, and servers through...deploying services,' this creates new application instances on infrastructure.

Verdict

create_application Rate-limited

create_application 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.
