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. Uses qso-graph-auth for credential management.

Install¶

uvx eqsl-mcp            # run it; nothing to install

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 your eQSL inbox as raw ADIF, to import into your logger
`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:

# Install qso-graph-auth if you haven't
uv tool install qso-graph-auth

# A persona (your callsign and the dates it covers), then eQSL for it
qso-auth persona add --name ki7mt --callsign KI7MT --start 2020-01-01
qso-auth provider enable ki7mt eqsl
qso-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.git
cd eqsl-mcp
uv sync --group dev
uv run pytest

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.

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.

License¶

GPL-3.0-or-later

Tool Reference¶

Generated from the released server's own tool definitions.

eqsl_ag_check¶

Check if a callsign has Authenticity Guaranteed (AG) status on eQSL.

Public, no auth required. Uses a cached copy of the AG member list (refreshed every 4 hours).

Parameter	Type	Required	Default	Description
`callsign`	string	Yes		The callsign to check.

eqsl_download¶

Download your complete eQSL inbox as raw ADIF text.

Returns the .adi file content — save to disk for import into your logger. Omit 'since' to download your entire inbox history.

Parameter	Type	Required	Default	Description
`persona`	string	Yes		Persona name configured in adif-mcp.
`since`	string	No	`null`	Only records added since this date (YYYY-MM-DD). Omit for full history.
`qth_nickname`	string	No	`null`	QTH profile name (for multi-QTH callsigns).

eqsl_inbox¶

Download incoming eQSLs (confirmations others have sent you).

Parameter	Type	Required	Default	Description
`persona`	string	Yes		Persona name configured in adif-mcp.
`since`	string	No	`null`	Only records added since this date (YYYY-MM-DD). Default: last 30 days.
`confirmed_only`	boolean	No	`false`	Only return records you have confirmed back.
`unconfirmed_only`	boolean	No	`false`	Only return records you have NOT confirmed.
`qth_nickname`	string	No	`null`	QTH profile name (for multi-QTH callsigns).

eqsl_last_upload¶

Check when a persona last uploaded QSOs to eQSL.

Parameter	Type	Required	Default	Description
`persona`	string	Yes		Persona name configured in adif-mcp.

eqsl_verify¶

Check if a specific QSO exists in eQSL (public, no auth required).

Parameter	Type	Required	Default	Description
`from_call`	string	Yes		Sender's callsign.
`to_call`	string	Yes		Receiver's callsign.
`band`	string	Yes		Band (e.g., '20m').
`qso_date`	string	Yes		QSO date in YYYY-MM-DD format.
`mode`	string	No	`null`	Mode (exact match — use 'USB' not 'SSB', 'PSK31' not 'PSK').

get_version_info¶

Get eqsl-mcp service version and upstream eQSL.cc endpoint version.

Returns the running PyPI version of eqsl-mcp and the eQSL.cc endpoint contract in use. Use this to confirm fleet alignment across MCP deployments — agents can compare service_version and spec_version across servers to detect drift without going outside the MCP protocol.

No parameters.
