Summary
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.

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.
- Resources
duplicacy://status,duplicacy://progressandduplicacy://healthfor read-only browsing. - Tools
get_backup_status,get_backup_history,list_snapshotsandget_prune_status. - One JSON-RPC endpoint (
/mcp) over HTTP, or stdio throughnpx duplicacy-mcp. - Listens on
127.0.0.1:8080by 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.
