Js8call MCP server

<!-- mcp-name: io.github.qso-graph/js8call-mcp -->

js8call-mcp

### In development

This package is published so the name is held while the work is planned in the open.

It registers one tool, getversioninfo, and does nothing else yet. If you install

it expecting a working server, that is what you will find — which is why it says so

here, in the server's own instructions, and in the one tool it has.

PyPI does not reserve a name for a pending trusted publisher, so a name is only held

once something is actually published. Given that, a package that says what it is beats

an empty one that does not.

Read-only access to JS8Call's API: the decode stream, stations heard, message traffic and the propagation those imply. No write, no PTT, no transmit control — a permanent constraint, not a first-version limit.

Planned work, including the data sources it would use and whether each is actually available, is tracked in qso-graph-devel#48.

Part of the qso-graph project.

Questions it will answer

Not yet — these are what the finished server is for:

"Who has JS8Call heard on 40m in the last hour?"

"What message traffic has come through for my callsign?"

"Which stations are relaying, and how far away are they?"
