Current use and fit

Most clearly implemented by Mudlet; any GMCP-capable engine can add it without another Telnet parser.

Implementation essentials

  • Negotiate GMCP first, then advertise only the Client.Media version implemented.
  • Use HTTPS, bounded downloads, stable cache identifiers, and explicit media types.

Compatibility and safety notes

  • Remote media remains an active-content boundary.
  • Do not override client media preferences.
