Common questions

Is Duplicacy MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 10 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js, Docker on your computer.

What can I use instead?

Duplicacy MCP

A tiny bridge that reads Duplicacy backup metrics from a Prometheus exporter and exposes them as an MCP server, enabling LLMs to monitor backup status, progress, and health.

Features

Reads the metrics of duplicacy-exporter and serves them over MCP.
One call answers "are my backups OK?": get_backup_overview gives every backup a verdict (ok, running, stale, never, failed) with a reason.
Speaks MCP 2026-07-28 (server/discover, stateless requests) and every earlier revision down to 2024-11-05 (the initialize handshake) from the same binary, over stdio and Streamable HTTP. Clients that still use the old handshake keep working.
Read-only by design: every tool and resource only reads the exporter, so there is no read-only flag to set. Every tool carries readOnlyHint, a title, an output schema and structured results.
HTTP listens on 127.0.0.1:8080 by default. On any other address it refuses to start without a bearer token, rejects cross-origin browser requests and caps request bodies.
Ships as Go binaries for several platforms (GoReleaser), a Docker image and an npm wrapper.

Tools and resources

Tool	What it answers
`get_backup_overview`	Health of every backup in one call: verdict, reason, age of the last success. `max_age_hours` (default 26) sets when a backup is stale.
`list_snapshots`	Every snapshot ID, storage target and machine, for use as filter values.
`get_backup_status`	State and last-run details of one snapshot, per storage target and machine.
`get_backup_history`	The last completed run of one snapshot. The exporter keeps only the last run.
`get_prune_status`	Whether a prune is running and when the last one succeeded, per storage target.
`get_storage_usage`	Storage size and chunks, and revisions per snapshot, from the exporter's storage poller.

Resources: duplicacy://status, duplicacy://progress and duplicacy://health. Parameters and output fields are on Usage.

Install

The npm package runs the server over stdio; set DUPLICACY_EXPORTER_URL to your exporter.

Claude Code

claude mcp add --transport stdio --env DUPLICACY_EXPORTER_URL=http://localhost:9750 duplicacy -- npx -y duplicacy-mcp

Claude Desktop (claude_desktop_config.json) and Cursor (~/.cursor/mcp.json)

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

VS Code (.vscode/mcp.json)

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

Codex (~/.codex/config.toml)

[mcp_servers.duplicacy]

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

npm 12, pnpm and Bun skip install scripts, so the wrapper downloads and verifies the binary on first start. Versions up to 0.1.2 relied on the install script alone; with npm 12 run them as npx -y --allow-scripts=duplicacy-mcp duplicacy-mcp.

Docker (Streamable HTTP)

export MCP_AUTH_TOKEN=$(openssl rand -hex 32)

docker run -d -p 127.0.0.1:8080:8080 -e MCP_AUTH_TOKEN \ -e DUPLICACY_EXPORTER_URL=http://duplicacy-exporter:9750 drumsergio/duplicacy-mcp:v0.2.0 claude mcp add --transport http duplicacy http://127.0.0.1:8080/mcp --header "Authorization: Bearer $MCP_AUTH_TOKEN"

The image listens on 0.0.0.0:8080 inside the container, so it will not start without MCP_AUTH_TOKEN (or MCP_ALLOW_UNAUTHENTICATED=true behind a reverse proxy that authenticates). Compose, a global npm install and a local build are in Getting started; every variable is in Configuration.
