duplicacy-mcp
MCP server for administering Duplicacy backups through the duplicacy-web API (the same internal HTTP API the web UI uses). Lets AI clients inspect storages, repositories, schedules and jobs, and create or delete them.
Built with the official Python MCP SDK 2.x (MCPServer, stdio transport).

Notes
- The duplicacy-web API is unauthenticated unless an administration token is set in the web UI. Keep the server on a trusted network.
- Storage passwords are the repository encryption keys — callers must supply them when creating a storage and store them somewhere safe (e.g. Infisical).
