List all available releases for an app
AI agents call faber_list_releases to retrieve information from Faber 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 information about available releases for a Laravel application. It performs a read-only operation that queries existing data without creating, modifying, deleting, or executing any operations. The action of listing is inherently non-destructive and has no blast radius if invoked by an AI agent.
