How do I install Duplicacy?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Duplicacy need an API key?

The publisher lists these environment variables: DUPLICACY_EXPORTER_URL.

What transport does Duplicacy use?

Duplicacy runs locally over stdio.

Remote URL or a command on your machine? How the two installs differ

Run on PlugMCP

Host a copy with our keys and logs.

A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.

Reads the metrics of duplicacy-exporter and serves them over MCP.
Resources duplicacy://status, duplicacy://progress and duplicacy://health for read-only browsing.
Tools get_backup_status, get_backup_history, list_snapshots and get_prune_status.
One JSON-RPC endpoint (/mcp) over HTTP, or stdio through npx duplicacy-mcp.
Listens on 127.0.0.1:8080 by default. Put a reverse proxy with authentication in front before exposing it.
Ships as Go binaries for several platforms (GoReleaser), a Docker image and an npm wrapper.

Quick start

docker run -d -p 127.0.0.1:8080:8080 -e DUPLICACY_EXPORTER_URL=http://duplicacy-exporter:9750 drumsergio/duplicacy-mcp:v0.1.0

That serves http://127.0.0.1:8080/mcp. For a client that starts the server itself over stdio, use the npm package in an mcpServers block:

{
  "mcpServers": {
    "duplicacy": {
      "command": "npx",
      "args": ["-y", "duplicacy-mcp"],
      "env": { "DUPLICACY_EXPORTER_URL": "http://localhost:9750" }
    }
  }
}

Compose, a global npm install and a local build are in Getting started.
