The same manual is built into the add‑on: the control panel shows it under Developer → Add‑ons → MCP Server For EE → Manual, and the release zip carries it at its root as DOCUMENTATION.md. The add‑on's overview is at multimediality.com/add-ons/mcp-server-for-ee, its license at /license and its full change history at /changelog.

Requirements

  • ExpressionEngine 7.2 or newer.
  • PHP 8.2+ with the openssl and fileinfo extensions (both standard on typical EE hosts; json is bundled into PHP core). The installer refuses to proceed if a required extension is missing.
  • A non‑empty encryption_key in your EE config (system/user/config/config.php). EE sets one on install; if yours is blank the add‑on refuses to create or rotate signing keys and tells you so in the control panel — it never falls back to a guessable key.
  • ExpressionEngine Pro is required only if you want members with multi‑factor authentication (MFA) to sign in — MFA support uses EE Pro's own machinery. Everything else works on standard EE.
  • Composer is not needed to install. The release zip ships with all dependencies bundled.

What’s new in 1.3.3

Changed

  • License terms. Support, Updates & Warranty in LICENSE again offers best-effort email support at [email protected] beside the updates a current license includes. The same terms as the website's license page and the other Multimediality add-ons.
  • Changelog format. CHANGELOG.md groups every release under Added, Changed, Removed, Fixed and Security, with Upgrading notes where a release needs a step; the release notes themselves are unchanged.
