Odel charges nothing per call. The publisher may charge for its own service.

Runs locally over stdio

This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).

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://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

bash

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:
