adif-mcp 1.0.3

ADIF MCP server — spec parsing, validation, and field enumeration tools

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.

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:

Category	Tool	Description
Validation	validate_adif_record	Validate a raw ADIF string against the 3.1.6 spec
Validation	parse_adif	Streaming parser for large ADIF files with pagination
Spec	read_specification_resource	Retrieve raw JSON for any spec module (band, mode, fields)
Spec	list_enumerations	List all ADIF enumerations with entry counts
Spec	search_enumerations	Search enumeration records by keyword
Geospatial	calculate_distance	Great Circle distance (km) between two Maidenhead locators
Geospatial	calculate_heading	Initial beam heading (azimuth) between two locators
System	get_version_info	Active service version and ADIF spec version

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:

Package	PyPI	What It Does
qso-graph-auth	v0.1.1	OS keyring credential management, persona CRUD
adif-mcp	v1.0.1	ADIF 3.1.6 spec tools, validation, parsing, geospatial
eqsl-mcp	v0.3.1	eQSL inbox, verification, AG status, last upload
qrz-mcp	v0.3.1	Callsign lookup, DXCC, logbook status/fetch
lotw-mcp	v0.3.1	LoTW confirmations, QSOs, DXCC credits, user activity
hamqth-mcp	v0.4.0	Callsign lookup, DXCC, bio, activity, DX spots, RBN, QSO verify
pota-mcp	v0.2.0	Parks on the Air spots, park info, stats, schedules
sota-mcp	v0.1.4	Summits on the Air spots, alerts, summit info, stats
solar-mcp	v0.2.0	Space weather conditions, forecasts, band outlook
wspr-mcp	v0.3.0	WSPR beacon spots, propagation, band activity
iota-mcp	v0.1.0	Islands on the Air lookup, search, nearby groups
n1mm-mcp	v0.1.4	N1MM Logger+ contest state via UDP
ionis-mcp	v1.2.8	HF propagation analytics (175M+ signatures)
qsp-mcp	v0.2.1	Local LLM ↔ MCP tool relay

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 3.1.6) 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
