ARRL Logbook of The World MCP server. QSO query, QSL status, DXCC credit tracking.
針對 ARRL Logbook of The World 的唯讀 MCP 伺服器，讓助理查詢 QSO、QSL 確認、DXCC 積分與呼號活躍情形。
Desktop only，透過 STDIO。 STDIO 服務會啟動本機處理程序，因此需要 SourceWeft 桌面主機。

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.
lotw-mcp uses qso-graph-auth personas for credential management:
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.
Add to claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows):
Add to .claude/settings.json:
Add to .cursor/mcp.json (project-level) or ~/.cursor/mcp.json (global):
Add to .vscode/mcp.json in your workspace:
Add to ~/.gemini/settings.json (global) or .gemini/settings.json (project):
"How many LoTW confirmations did I get this month?"
"Show me all unconfirmed 20m FT8 QSOs uploaded to LoTW in the last 90 days"
"What DXCC credits do I have on 40m CW?"
"Does JA1ABC use LoTW? When did they last upload?"
lotw_user_activity works without any credentials. It uses the public LoTW user activity CSV, cached locally for 7 days.
Set the mock environment variable:
LoTW can be slow (30-60s for large queries). lotw-mcp uses 120s timeouts. Use date filters (since, start_date) to limit result sets.

Get Version Info
Get lotw-mcp service version and upstream LoTW schema version. Returns the running PyPI version of lotw-mcp and the ARRL LoTW ADIF/CSV export schema in use. Use this to confirm fleet alignment across MCP deployments — agents can compare service_version and spec_version across servers to detect drift without going outside the MCP protocol.
無需輸入參數。
Lotw Confirmations
Query confirmed QSL records from LoTW.
