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. It runs locally over stdio via the published package.

People who work with adif, amateur radio and eqsl and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Adif MCP

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add qso-graph-adif-mcp -- uvx adif-mcp

Claude Desktop / Cursor / VS Code - add to config

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

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package adif-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.qso-graph is GitHub-verified and matches the repo owner
