Overview

Description from the maker (original English)

ADIF 3.1.7 spec engine for amateur radio logs: validation, parsing, enumerations, geospatial.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "adif": {
      "command": "uvx",
      "args": [
        "adif-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add adif -- uvx adif-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "adif": {
      "command": "uvx",
      "args": [
        "adif-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "adif": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "adif-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Adif MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.1.1) reached the registry 9 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

adif-mcp

MCP server for the ADIF 3.1.7 specification: validate and parse ADIF records, search the spec's fields, enumerations and data types, and compute distance and heading between Maidenhead locators, through any MCP-compatible AI assistant.

Part of the qso-graph project. No authentication required — the ADIF specification is bundled, so it works offline.

Install

uvx adif-mcp            # run it; nothing to install

What is ADIF?

ADIF (Amateur Data Interchange Format) is the standard file format amateur radio logging programs use to exchange QSO records. adif-mcp is the specification package of qso-graph: it validates, parses and searches ADIF so an assistant can work with logs safely and accurately. Credentials are handled separately by qso-graph-auth, and each logging service has its own MCP server (see qso-graph.io).

Quick Start

No credentials needed — just install and configure your MCP client.

Configure your MCP client

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

Claude Desktop

Add to claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows):

{

"mcpServers": { "adif": { "command": "uvx", "args": ["adif-mcp"] } } }

Claude Code

Add to .claude/settings.json:

{

"mcpServers": { "adif": { "command": "uvx", "args": ["adif-mcp"] } } }

ChatGPT Desktop

Configure via Settings > Apps & Connectors, or in your agent definition:

{

"mcpServers": { "adif": { "command": "uvx", "args": ["adif-mcp"] } } }

Cursor

Add to .cursor/mcp.json (project-level) or ~/.cursor/mcp.json (global):

{

"mcpServers": { "adif": { "command": "uvx", "args": ["adif-mcp"] } } }

VS Code / GitHub Copilot

Add to .vscode/mcp.json in your workspace:

{

"servers": { "adif": { "command": "uvx", "args": ["adif-mcp"] } } }

Gemini CLI

Add to ~/.gemini/settings.json (global) or .gemini/settings.json (project):

{

"mcpServers": { "adif": { "command": "uvx", "args": ["adif-mcp"] } } }

Ask questions

"Is this ADIF record valid? KI7MT 20260928 20m SSB "

"What values does the ADIF MODE enumeration allow for digital modes?"

"Parse my log file and show me the first 50 QSOs."

"How far is it from DN13 to JN48, and what heading should I point the beam?"

What the validator checks

adif-mcp ships ADIF 3.1.7 as ADIF publishes it: 186 fields, 25 enumerations and 28 data types. validate_adif_record checks each field against its ADIF data type and, for enumerated fields, against the enumeration:

  • Enumeration values match regardless of case, so LoTW's BAND=15M is accepted as 15m.
  • Import-only values (42 of the Mode enumeration's 91 entries, for example) give a warning, not an error: ADIF allows them on import but not in new records.
  • Compound values such as CREDIT_SUBMITTED (a list of Credit or Credit:Medium entries) are checked entry by entry.
  • SUBMODE must be a valid Submode; one that belongs to a different MODE gives a warning. FT4, for example, is MODE=MFSK with SUBMODE=FT4.
  • Structured types are checked against the grammar ADIF states for them: grid squares (2, 4, 6 or 8 characters, any case) and their extensions and lists (VUCC needs two or four, each four or six characters), Location (XDDD MM.MMM), Boolean (Y or N), and IOTA, WWFF, POTA and SOTA references. What the grammar allows but cannot be right, such as a latitude over 90 degrees or N/S on a longitude, is a warning, never an error.

The server also publishes the MCP resource adif://system/version: the service version and the ADIF specification version it serves.

The ADIF specification files are not ours. The package includes ADIF's published files for two versions, the previous and the current (3.1.6 and 3.1.7 today), unmodified: every file in ADIF's resource zip except its test material, in every format ADIF publishes (JSON, XML with all.xml and the XSD, CSV, TSV, XLSX, ODS), with a MANIFEST.json of their SHA-256s per version, from the ADIF Developers Group. They are ADIF's work, and our licence doesn't cover them. The only files in that folder that are ours are the derived Country enumeration and each version's MANIFEST.json. See NOTICE.
