# eqsl-mcp

MCP server for [eQSL.cc](https://www.eqsl.cc/) — download incoming eQSLs, verify QSOs, check AG status, and query upload history through any MCP-compatible AI assistant.

Part of the [qso-graph](https://qso-graph.io/) project. Uses [qso-graph-auth](https://pypi.org/project/qso-graph-auth/) for credential management.

## Install

```bash
pip install eqsl-mcp
```

## Tools

| Tool | Auth | Description |
|------|------|-------------|
| `eqsl_inbox` | Yes | Download incoming eQSLs with date/confirmation filters |
| `eqsl_verify` | No | Check if a specific QSO exists in eQSL |
| `eqsl_ag_check` | No | Check if a callsign has AG (Authenticity Guaranteed) status |
| `eqsl_download` | Yes | Download eQSL card images |
| `eqsl_last_upload` | No | When did a persona last upload to eQSL |
| `get_version_info` | No | Service version + upstream eQSL.cc endpoint version (fleet identity attestation) |

## Quick Start

### 1. Set up credentials

eqsl-mcp uses qso-graph-auth personas for credential management:

```bash
# Install qso-graph-auth if you haven't
pip install qso-graph-auth

# Create a persona and add eQSL credentials
qso-auth persona create ki7mt --callsign KI7MT
qso-auth persona provider ki7mt eqsl --username KI7MT
qso-auth persona secret ki7mt eqsl
```

### 2. Configure your MCP client

eqsl-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": {
    "eqsl": {
      "command": "eqsl-mcp"
    }
  }
}
```

#### Claude Code

Add to `.claude/settings.json`:

```json
{
  "mcpServers": {
    "eqsl": {
      "command": "eqsl-mcp"
    }
  }
}
```

#### ChatGPT Desktop

ChatGPT supports MCP via the [OpenAI Agents SDK](https://developers.openai.com/api/docs/mcp/). Add under Settings > Apps & Connectors, or configure in your agent definition:

```json
{
  "mcpServers": {
    "eqsl": {
      "command": "eqsl-mcp"
    }
  }
}
```

#### Cursor

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

```json
{
  "mcpServers": {
    "eqsl": {
      "command": "eqsl-mcp"
    }
  }
}
```

#### VS Code / GitHub Copilot

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

```json
{
  "servers": {
    "eqsl": {
      "command": "eqsl-mcp"
    }
  }
}
```

#### Gemini CLI

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

```json
{
  "mcpServers": {
    "eqsl": {
      "command": "eqsl-mcp"
    }
  }
}
```

### 3. Ask questions

> "Show me all eQSLs received this week"

> "How many unconfirmed eQSLs do I have on 20m FT8?"

> "Does W1AW have AG status on eQSL?"

> "Verify my QSO with KI7MT on 20m on March 1, 2026"

## Testing Without Credentials

The two public tools (`eqsl_verify` and `eqsl_ag_check`) work without any credentials.

For `eqsl_inbox` testing, set the mock environment variable:

```bash
EQSL_MCP_MOCK=1 eqsl-mcp
```

Or point to a local ADIF file:

```bash
EQSL_MCP_MOCK=1 EQSL_MCP_ADIF=/path/to/test.adi eqsl-mcp
```

## MCP Inspector

```bash
eqsl-mcp --transport streamable-http --port 8001
```

Then open the MCP Inspector at `http://localhost:8001`.

## Development

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

## Date Formats

eQSL uses different date formats across endpoints. eqsl-mcp normalizes everything — you always use `YYYY-MM-DD`:

| You provide | eqsl-mcp sends | Endpoint |
|-------------|----------------|----------|
| `2026-03-01` | `202603010000` | DownloadInBox (RcvdSince) |
| `2026-03-01` | `03/01/2026` | VerifyQSO (QSODate) |

## Mode Matching

eQSL requires exact mode matching. `SSB` won't match `USB`/`LSB`. `PSK` won't match `PSK31`. Use the exact mode logged by the other station.
