Documentation
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. It also provides persona management and keyring-backed credential storage used by the qso-graph family of MCP servers.
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 foundation package -- ADIF spec tools, persona management, and credential storage. Service integrations are separate MCP servers that depend on adif-mcp for identity and auth:
| Package | PyPI | What It Does |
|---|---|---|
adif-mcp | v0.9.6 | ADIF 3.1.6 spec tools + persona/credential management |
lotw-mcp | v0.2.0 | LoTW confirmations, QSOs, DXCC credits, user activity |
eqsl-mcp | v0.2.0 | eQSL inbox, verification, AG status, last upload |
qrz-mcp | v0.2.1 | Callsign lookup, DXCC, logbook status/fetch |
hamqth-mcp | v0.2.0 | Callsign lookup, DXCC, bio, activity, DX spots, RBN |
pota-mcp | v0.1.1 | Parks on the Air spots, park info, stats, schedules |
sota-mcp | v0.1.1 | Summits on the Air spots, alerts, summit info, stats |
solar-mcp | v0.1.1 | Space weather conditions, forecasts, band outlook |
wspr-mcp | v0.1.1 | WSPR beacon spots, propagation, band activity |
iota-mcp | v0.1.0 | Islands on the Air lookup, search, nearby groups |
Authenticated servers use adif-mcp 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 engineADIF-MCP-LOTW-- LoTW serverADIF-MCP-EQSL-- eQSL serverADIF-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 operationAPP_ADIF-MCP-EQSL_TIME-- timestamp of eQSL merge
