adif-mcp 0.6.2

ADIF MCP core engine with plugin support (LoTW, eQSL, QRZ, Clublog)

adif-mcp

Core Model Context Protocol (MCP) server for Amateur Radio Logging, built on the ADIF 3.1.6 specification.

Overview

adif-mcp gives AI agents safe, typed access to Amateur Radio logging data. It validates and parses ADIF records, searches the full ADIF 3.1.6 specification (fields, enumerations, data types), and provides geospatial utilities for Maidenhead locators. A plugin system supports service integrations for LoTW, eQSL, QRZ, and Club Log.

Quick Start

pip install adif-mcp

Spec	read_specification_resource	Retrieve raw JSON for any spec module (band, mode, fields)
Spec	search_enumerations	Search administrative subdivision records

System	get_version_info	Active service version and ADIF spec version

ADIF-MCP Engines

This package defines the ADIF MCP core engine, with plugins for:

• LoTW (adif-mcp-lotw) -- ARRL Logbook of The World: confirmations, awards tracking, uploads
• eQSL (adif-mcp-eqsl) -- eQSL.cc: electronic QSL confirmations and awards
• QRZ (adif-mcp-qrz) -- QRZ.com: callsign lookup and logbook integration
• Club Log (adif-mcp-clublog) -- Club Log: DXCC matching, OQRS, expedition logs

MCP doesn't replace LoTW, eQSL, Club Log, QRZ, or any award/logging program. Instead, it gives operators visibility and accessibility into their award progress, across sponsors, without needing to export, filter, or code.

Compliance & Provenance

adif-mcp follows the ADIF Specification (currently 3.1.6) and uses registered Program IDs to identify all exports:

• ADIF-MCP -- Core engine
• ADIF-MCP-LOTW -- LoTW plugin
• ADIF-MCP-EQSL -- eQSL plugin
• ADIF-MCP-QRZ -- QRZ plugin
• ADIF-MCP-CLUBLOG -- Club Log plugin

The project uses APP_ fields for provenance when augmenting records:

• APP_ADIF-MCP_OP -- operation performed (normalize, validate, merge)
• APP_ADIF-MCP-LOTW_ACTION -- LoTW plugin operation
• APP_ADIF-MCP-EQSL_TIME -- timestamp of eQSL merge

See the Program ID & APP_ Field Policy for full details.
