WHAT IT DOES

What import_registry_spec does on Nitrostack

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

RISK

Why import_registry_spec is rated Medium

An AI agent can call import_registry_spec faster than any human can review: one bad instruction and it creates or modifies resources in Nitrostack by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs import_registry_spec safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nitrostack, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For import_registry_spec, this is the rule to start with:

import_registry_spec Rate-limited

import_registry_spec 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.
