Common questions

Is Qrz 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 (0.6.3) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

qrz-mcp

MCP server for QRZ.com — callsign lookups, DXCC entity resolution, and logbook queries through any MCP-compatible AI assistant.

Part of the qso-graph project. Uses qso-graph-auth for credential management.

Install

uvx qrz-mcp            # run it; nothing to install

Tools

Tool	API	Auth	Description
`qrz_lookup`	XML	Session key	Callsign lookup (name, grid, DXCC, license class, QSL info, image)
`qrz_dxcc`	XML	Session key	DXCC entity resolution from callsign or entity code
`qrz_logbook_status`	Logbook	API key	Logbook stats (QSO count, DXCC total, date range)
`qrz_logbook_fetch`	Logbook	API key	Query QSOs with filters and transparent pagination
`qrz_download`	Logbook	API key	Download full logbook as ADIF
`get_version_info`	—	None	Service version + upstream QRZ API version (fleet identity attestation)

Quick Start

1. Set up credentials

qrz-mcp uses qso-graph-auth personas for credential management. QRZ has two separate auth mechanisms, exposed as two providers — set up whichever you need:

Provider	Tools	Credentials
`qrz`	`qrz_lookup`, `qrz_dxcc`	username + password
`qrz_logbook`	`qrz_logbook_status`, `qrz_logbook_fetch`, `qrz_download`	username + API key

# Install qso-graph-auth if you haven't

uv tool install qso-graph-auth

Create a persona (--start is required)

qso-graph-auth persona add --name ki7mt --callsign KI7MT --start 2018-01-01

XML API (qrz_lookup, qrz_dxcc)

qso-graph-auth provider enable ki7mt qrz qso-graph-auth creds set ki7mt qrz # asks for your username, then your password (hidden)

Logbook API (qrz_logbook_status, qrz_logbook_fetch, qrz_download)

qso-graph-auth provider enable ki7mt qrz_logbook qso-graph-auth creds set ki7mt qrz_logbook # asks for your username, then your API key

Verify

qso-graph-auth creds doctor

Pass the persona name (ki7mt above) as the persona argument on every tool call.

Omit --password / --api-key to be prompted instead — passing secrets as CLI arguments leaves them in your shell history.

XML API (callsign lookup, DXCC) requires a QRZ XML Subscription ($35.95/yr). Free tier returns name and address only.

Logbook API requires an API key from QRZ Settings > API.

2. Configure your MCP client

qrz-mcp works with any MCP-compatible client. Add the server config and restart — tools appear automatically.
