Summary

Connects your AI assistant to HamQTH.com's amateur radio database for callsign lookups, DX cluster spots, and Reverse Beacon Network data. You get eight tools covering operator info (name, grid, DXCC, QSL preferences), biographies, recent activity, live propagation data filtered by band or mode, and QSO verification through the SAVP protocol. Most tools require a free HamQTH account managed through the qso-graph persona system, but DXCC resolution and some queries work unauthenticated. Built for ham radio operators who want to query callsigns, track DX activity, or verify contacts without leaving their editor or chat interface.

hamqth-mcp

MCP server for HamQTH.com — callsign lookup, DX cluster spots, Reverse Beacon Network, DXCC resolution, and more through any MCP-compatible AI assistant.

Part of the qso-graph project. Authenticated tools use qso-graph-auth for persona and credential management.

Install

pip install hamqth-mcp

Tools

ToolAuthDescription
hamqth_lookupYesCallsign lookup (name, grid, DXCC, coordinates, QSL preferences)
hamqth_dxccNoResolve DXCC entity from callsign or ADIF code
hamqth_bioYesFetch operator biography
hamqth_activityYesRecent DX cluster, RBN, and logbook activity
hamqth_dx_spotsNoLive DX cluster spots — filter by band and/or callsign
hamqth_rbnNoReverse Beacon Network decodes — filter by band, mode, continent, callsign
hamqth_verify_qsoNoVerify a QSO via HamQTH SAVP protocol
get_version_infoNoService version + upstream HamQTH API version (fleet identity attestation)

Quick Start

1. Create a free HamQTH account

Sign up at hamqth.com — it's free, no subscription required.

2. Set up credentials

hamqth-mcp uses adif-mcp personas for credential management:

# Install adif-mcp if you haven't
pip install adif-mcp

# Create a persona and add HamQTH credentials
adif-mcp persona create ki7mt --callsign KI7MT
adif-mcp persona provider ki7mt hamqth --username KI7MT
adif-mcp persona secret ki7mt hamqth

3. Configure your MCP client

hamqth-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": {
    "hamqth": {
      "command": "hamqth-mcp"
    }
  }
}
Claude Code

Add to .claude/settings.json:

{
  "mcpServers": {
    "hamqth": {
      "command": "hamqth-mcp"
    }
  }
}
ChatGPT Desktop
{
  "mcpServers": {
    "hamqth": {
      "command": "hamqth-mcp"
    }
  }
}
Cursor

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

{
  "mcpServers": {
    "hamqth": {
      "command": "hamqth-mcp"
    }
  }
}
VS Code / GitHub Copilot

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

{
  "servers": {
    "hamqth": {
      "command": "hamqth-mcp"
    }
  }
}
Gemini CLI

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

{
  "mcpServers": {
    "hamqth": {
      "command": "hamqth-mcp"
    }
  }
}

4. Ask questions

"Look up the callsign OK2CQR"

"What DXCC entity is VP8PJ?"

"Show me the biography for OK2CQR"

"What's the recent activity for KI7MT?"

"Show me DX spots for 3Y0K"

"What RBN decodes are there for 3Y0K on CW?"

"Show me 20m DX spots"

"Verify my QSO with OK2CQR on 20m on March 5"

Testing Without Credentials

The DXCC tool (hamqth_dxcc) works without any credentials — it uses a public endpoint.

For testing all tools without a HamQTH account:

HAMQTH_MCP_MOCK=1 hamqth-mcp

MCP Inspector

hamqth-mcp --transport streamable-http --port 8005

Then open the MCP Inspector at http://localhost:8005.

Development

git clone https://github.com/qso-graph/hamqth-mcp.git
cd hamqth-mcp
pip install -e .
