Stash this in ~/.local/share/man/man1 and you're good. This is unofficial and generated by Claude. I was trying to figure out a "launch to system tray" for KDE, so it has a bit of a focus on that.

.SH TRAY BEHAVIOR
Claude Desktop includes system tray integration. Behavior is controlled by the application, not command-line flags:
.PP
.IP \(bu 2
Minimizing sends window to tray (if tray enabled in settings)
.IP \(bu 2
Closing window may minimize to tray (configurable)
.IP \(bu 2
Right-click tray icon for menu options
.IP \(bu 2
Click tray icon to restore window
.PP
.B Note:
No command-line flag exists to start minimized to tray. This must be configured in application settings or by modifying the launcher script.
.SH KDE INTEGRATION
To create a launcher that minimizes to tray on startup, modify the desktop entry:
.PP
.nf
Exec=claude-desktop %U
.fi
.PP
Or create a custom launcher script at
.I ~/bin/claude-tray
that launches and immediately minimizes the window using xdotool or wmctrl.
.SH MODEL CONTEXT PROTOCOL
MCP servers are configured in:
.PP
.I ~/.config/Claude/claude_desktop_config.json
.PP
Example configuration:
.PP
.nf
{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "/home/user/Documents"]
    }
  }
}
.fi
