Eqsl Mcp

eqsl-mcp

[PyPI] [MCP Registry]

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. Uses qso-graph-auth for credential management.

Install

uvx eqsl-mcp            # run it; nothing to install

Tools

Quick Start

1. Set up credentials

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

# Install qso-graph-auth if you haven'tuv tool install qso-graph-auth
# A persona (your callsign and the dates it covers), then eQSL for itqso-graph-auth persona add --name ki7mt --callsign KI7MT --start 2020-01-01qso-graph-auth provider enable ki7mt eqslqso-graph-auth creds set ki7mt eqsl      # asks for your username, then your password (hidden)

All three steps are needed: without provider enable, the server reports that the persona has no eqsl ref.

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": "uvx",      "args": ["eqsl-mcp"]    }  }}

Claude Code

Add to .claude/settings.json:

{  "mcpServers": {    "eqsl": {      "command": "uvx",      "args": ["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": "uvx",      "args": ["eqsl-mcp"]    }  }}

Cursor

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

{  "mcpServers": {    "eqsl": {      "command": "uvx",      "args": ["eqsl-mcp"]    }  }}

VS Code / GitHub Copilot

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

{  "servers": {    "eqsl": {      "command": "uvx",      "args": ["eqsl-mcp"]    }  }}

Gemini CLI

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

{  "mcpServers": {    "eqsl": {      "command": "uvx",      "args": ["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.gitcd eqsl-mcpuv sync --group devuv run pytest

Date Formats

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

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.

Known Quirks

• AG list cache: the Authenticity Guaranteed member list is cached for 4 hours (eQSL updates it about six times a day), in ~/.cache/eqsl-mcp/ag_members.txt ($XDG_CACHE_HOME if set; %LOCALAPPDATA%\eqsl-mcp\ on Windows).
• Inbox download: eQSL returns an HTML page that links to the .adi file, so the inbox is fetched in two steps. If eQSL answers with ADIF directly, that is used as is.
