create_service · Packmate MCP: Risk & Policy

WHAT IT DOES

What create_service does on Packmate

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

WHY IT NEEDS A POLICY

Why create_service needs a policy

This tool creates new data reversibly within the system. While it modifies the state of the Packmate application, it does not irreversibly delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read). It is most appropriately classified as Write.

From the tool's definition Tool name 'create_service' and description 'Create a new service' indicate creation of new data/entities in the Packmate system. The context of a CTF network traffic analyzer suggests this creates service definitions or configurations.

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.
