Delete a collection and all its documents
AI agents call delete_collection to permanently remove resources in MCP MAGMA Handbook Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a collection and its entire contents without possibility of recovery (typical of handbook/database deletion operations). The blast radius is high if an agent mistakenly deletes a collection containing important documentation or indexed resources.
From the tool's definition Tool name is 'delete_collection' with description 'Delete a collection and all its documents' — explicit use of 'delete' and 'all its documents' indicates irreversible removal of data.
