adif-mcp

Core Model Context Protocol (MCP) server for Amateur Radio Logging, built on the ADIF 3.1.7 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 3.1.7 specification (fields, enumerations, data types), and provides geospatial utilities for Maidenhead locators.

Quick Start

pip install adif-mcp

Configure Your MCP Client

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

Tools

adif-mcp exposes 8 tools via the Model Context Protocol:

Architecture

adif-mcp is the ADIF specification package -- validation, parsing, and geospatial tools. Credential management is handled by qso-graph-auth. Service integrations are separate MCP servers:

Authenticated servers use qso-graph-auth for persona lookup and keyring-backed credentials. Operators install only the servers they need. Each server is independently versioned with no unnecessary dependencies.

Compliance & Provenance

adif-mcp follows the ADIF Specification (currently 3.1.7) and uses registered Program IDs to identify all exports:

• ADIF-MCP -- Core engine

• ADIF-MCP-LOTW -- LoTW server

• ADIF-MCP-EQSL -- eQSL server

• ADIF-MCP-QRZ -- QRZ server

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 server operation

• APP_ADIF-MCP-EQSL_TIME -- timestamp of eQSL merge
