create-service · Koyeb MCP Server MCP: Risk & Policy

WHAT IT DOES

What create-service does on Koyeb MCP Server

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

WHY IT NEEDS A POLICY

Why create-service needs a policy

This tool creates new resources (services) within the Koyeb platform, which is a modification operation. It is not destructive (the service can be deleted), not financial, and not an arbitrary code execution—it is a structured resource creation. However, the severity is high because creating services could involve deploying code that runs in production, consuming resources, and affecting application availability.

From the tool's definition Tool name 'create-service' and description 'Create a new service inside an existing app' indicate creation of new infrastructure resources. This is a reversible write operation that modifies the application state by adding a new service component.

Verdict

create-service Rate-limited

create-service 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.
