MCP server for [HamQTH.com](https://www.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](https://qso-graph.io/) project. Authenticated tools use [qso-graph-auth](https://pypi.org/project/qso-graph-auth/) for persona and credential management.

## Install

```bash
uvx hamqth-mcp            # run it; nothing to install

## Quick Start

### 1. Create a free HamQTH account

Sign up at [hamqth.com](https://www.hamqth.com/) — it's free, no subscription required.

### 2. Set up credentials

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

```bash
# 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):

```json
{
  "mcpServers": {
    "hamqth": {
      "command": "uvx",
      "args": ["hamqth-mcp"]
    }
  }
}
```

#### Claude Code

Add to `.claude/settings.json`:

```json
{
  "mcpServers": {
    "hamqth": {
      "command": "uvx",
      "args": ["hamqth-mcp"]
    }
  }
}
```

#### ChatGPT Desktop

```json
{
  "mcpServers": {
    "hamqth": {
      "command": "uvx",
      "args": ["hamqth-mcp"]
    }
  }
}
```

#### Cursor

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

```json
{
  "mcpServers": {
    "hamqth": {
      "command": "uvx",
      "args": ["hamqth-mcp"]
    }
  }
}
```

#### VS Code / GitHub Copilot

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

```json

      "args": ["hamqth-mcp"]
    }
  }
}
```

      "args": ["hamqth-mcp"]
    }
  }
}
```

Installed with pip instead? Use `"command": "hamqth-mcp"` in any config above.

### 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:

```bash
HAMQTH_MCP_MOCK=1 hamqth-mcp
```

## MCP Inspector

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

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

## Development

```bash
git clone https://github.com/qso-graph/hamqth-mcp.git
cd hamqth-mcp
uv sync --group dev
uv run pytest
```
