Qrz Mcp
Wraps QRZ.com's XML and Logbook APIs for ham radio callsign lookups, DXCC entity resolution, and logbook queries. Six tools cover the essentials: callsign lookup returns grid, license class, and QSL info; DXCC resolution maps callsigns to entities; logbook tools fetch QSO counts, query contacts with filters, and download full logs as ADIF. Built for the qso-graph project and uses qso-graph-auth personas for credential management. QRZ has two separate auth systems (XML subscription for lookups, API key for logbook), and the server handles both. Includes aggressive rate limiting and caching to avoid QRZ's undocumented limits and 24-hour IP bans. Useful if you're building logging tools or need callsign data in AI workflows.
