List supported Apps and Versions.
AI agents call mittwald_app_versions to retrieve information from Mittwald MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays metadata about supported applications and their versions. It queries existing data without creating, modifying, deleting, or executing any operations. The read-only nature combined with the informational scope (supported versions are typically public or non-sensitive deployment metadata) results in low severity. An AI agent misusing this tool would have minimal harmful impact.
