WHAT IT DOES

What generate_app_manifest does on GreenNode MCP Server

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

WHY IT NEEDS A POLICY

Why generate_app_manifest needs a policy

Given the empty description and reliance on naming convention alone, confidence is reduced but the tool most likely creates or generates configuration data (Write category) rather than merely reading it. In a Kubernetes/infrastructure context, manifest generation could enable deployment of arbitrary workloads if combined with apply_yaml, representing a high severity risk if an AI agent generates malicious manifests.

From the tool's definition Tool name 'generate_app_manifest' suggests creation of application manifests. The description is empty, limiting direct confirmation, but context shows this server manages Kubernetes resources and sibling tools include 'apply_yaml' which applies manifests.
