Common questions

Is Lotw 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 (0.6.2) reached the registry 9 days ago.

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?

lotw-mcp

MCP server for ARRL Logbook of The World (LoTW) — query confirmations, uploaded QSOs, DXCC credits, and user activity through any MCP-compatible AI assistant.

Part of the qso-graph project. Read-only — uploads require TQSL digital signatures and are out of scope.

Install

uvx lotw-mcp            # run it; nothing to install

Tools

Tool	Auth	Description
`lotw_confirmations`	Yes	Query confirmed QSLs with band/mode/call/date filters
`lotw_qsos`	Yes	Query all uploaded QSOs (confirmed and unconfirmed)
`lotw_dxcc_credits`	Yes	DXCC award credits from LoTW confirmations
`lotw_download`	Yes	Download QSOs as ADIF file
`lotw_user_activity`	No	Check if a callsign uses LoTW and when they last uploaded
`get_version_info`	No	Service version + upstream LoTW schema version (fleet identity attestation)

Quick Start

1. Set up credentials

lotw-mcp uses qso-graph-auth personas for credential management:

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

uv tool install qso-graph-auth

A persona (your callsign and the dates it covers), then LoTW for it

qso-graph-auth persona add --name ki7mt --callsign KI7MT --start 2020-01-01 qso-graph-auth provider enable ki7mt lotw qso-graph-auth creds set ki7mt lotw # asks for your username, then your password (hidden)

All three steps are needed: without provider enable, the server reports that the persona has no lotw ref.

Note: The LoTW login is usually your callsign but not always. Pre-Sept 2019 accounts may require lowercase passwords. Avoid special characters in passwords.

2. Configure your MCP client

Claude Desktop

Add to claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows):
