Duplicacy MCP
This server bridges Duplicacy backup monitoring into your LLM by reading metrics from a Prometheus exporter. You get four resources (status, progress, health) and four tools (get_backup_status, get_backup_history, list_snapshots, get_prune_status) for querying backup state without touching the filesystem directly. It speaks JSON-RPC over HTTP or stdio, runs as a tiny Go binary, and ships with Docker Compose configs. If you're already running duplicacy-exporter and want Claude to answer questions about backup health, snapshot counts, or prune operations without writing custom scripts, this is the connector. Supports local installs via npm or direct Go builds.
