mcp-prtg

MCP Server for PRTG Network Monitor (read-only).

Allows Claude to query sensors, devices, groups, channels, historical data, and system status from your PRTG instance via the classic PRTG HTTP API (v1). Supports self-signed SSL certificates.

Note: This server uses the classic PRTG API (/api/table.json, /api/historicdata.json, etc.), which is available in all PRTG versions. PRTG also offers a newer REST API v2 (available since v21.4.73 on port 1616) that is not yet supported by this server.

Authentication

This server authenticates using username + passhash. API tokens and plaintext passwords are not supported.

Getting your passhash

Open this URL in your browser (replace with your PRTG server, user, and password):

https://prtg.example.com/api/getpasshash.htm?username=myuser&password=mypassword
