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.

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
