eqsl-mcp

MCP server for 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 project. Depends on adif-mcp for persona and credential management.

Install

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_last_upload	No	When did a persona last upload to eQSL

Quick Start

1. Set up credentials

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

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

# Create a persona and add eQSL credentials
adif-mcp persona create ki7mt --callsign KI7MT
adif-mcp persona provider ki7mt eqsl --username KI7MT
adif-mcp 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):

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

Claude Code

Add to .claude/settings.json:

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

ChatGPT Desktop

ChatGPT supports MCP via the OpenAI Agents SDK. Add under Settings > Apps & Connectors, or configure in your agent definition:

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

Cursor

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

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

VS Code / GitHub Copilot

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

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

Gemini CLI

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

{
  "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:

EQSL_MCP_MOCK=1 eqsl-mcp

Or point to a local ADIF file:

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

MCP Inspector

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

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

Development

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.
