Summary
If you're working with amateur radio logs, this gives Claude direct access to ADIF 3.1.7 validation and parsing. You get eight tools: validate records against spec, parse large log files with pagination, search the full enumeration database for bands and modes, and run geospatial calculations on Maidenhead locators for distance and beam heading. It's the foundation layer in a larger qso-graph ecosystem that includes separate MCP servers for eQSL, LoTW, QRZ, POTA, SOTA, and propagation data. Useful if you need to validate imported logs, cross-reference field definitions during development, or calculate QSO geometry without leaving your editor.

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.
Claude Desktop
Add to claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows):
{
"mcpServers": {
"adif": {
"command": "adif-mcp"
}
}
}

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 3.1.7 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 | v1.1.0 | ADIF 3.1.7 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 | v0.2.1 | Parks on the Air spots, park info, stats, schedules |
sota-mcp | v0.1.5 | Summits on the Air spots, alerts, summit info, stats |
solar-mcp | v0.2.0 | Space weather conditions, forecasts, band outlook |
wspr-mcp | v0.3.1 | WSPR beacon spots, propagation, band activity |
iota-mcp | v0.1.1 | Islands on the Air lookup, search, nearby groups |
n1mm-mcp | v0.1.3 | 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 3.1.7) 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
