 * Plugin Name:       AdMindra MCP – AI Connector for ChatGPT & Claude
 * Plugin URI:        https://admindra.com/wordpress-plugin/#admindra-mcp
 * Description:       Let ChatGPT or Claude check, explain and edit the content of your site over MCP with OAuth. Content edits only when you switch them on; nothing else is changed.
 * Version:           1.2.1
 * Requires at least: 6.9
 * Requires PHP:      8.0
 * Author:            Viktor Grahn, 3on Reklambyrå &amp; Webbyrå AB (AdMindra)
 * Author URI:        https://admindra.com
 * License:           GPL-2.0-or-later

 * ---------------------------------------------------------------------
 * EXTERNAL SERVICES — disclosed here and in readme.txt.
 *
 * This plugin sends nothing to AdMindra. It is a read-only server for an AI
 * client the site's administrator chooses (ChatGPT by OpenAI, or Claude by
 * Anthropic). It contacts that provider only while the administrator
 * connects it: the OAuth client metadata document is fetched from
 * chatgpt.com or claude.ai. After the administrator approves the consent
 * screen, the connected client receives the results of the tools it calls.
 * The "updates" tool uses WordPress's own update check at api.wordpress.org.
 * Each service, with what is sent and when, is listed under
 * "External services" in readme.txt.
 *
 * ---------------------------------------------------------------------
 * NO REMOTE ADMINISTRATION SINCE 1.1.0.
 *
 * 1.0.0 could also replace plugin and theme files and run updates when an
 * administrator switched that on. The plugin directory treats that as
 * remote administration of the site, so it left this plugin: no ability,
 * no switch, no updater here. What remains changes content only — posts,
 * pages, the title and tagline — behind its own switch, with revisions.
 * The file and update abilities are an add-on from admindra.com
 * (AdMindra MCP Maintenance), which hooks its panel into the settings
 * screen through the admindra_mcp_addon_panel action.
 *
 * ---------------------------------------------------------------------
 * MCP ADAPTER IS ASKED FOR, NOT REQUIRED BY HEADER, SINCE 1.1.1.
 *
 * With a Requires Plugins header naming mcp-adapter, WordPress refused to activate the
 * uploaded zip and showed a bare error page, which looked as if the plugin
 * broke the site. Now it always activates and offers the step itself
 * (includes/class-admindra-mcp-setup.php), through WordPress's own install
 * screen. Without MCP Adapter the tools are registered but not served.
 *
 * ---------------------------------------------------------------------
 * THIS PLUGIN WAS "AdMindra WP MCP" (folder admindra-wp-mcp) up to 0.11.0.
 *
 * The plugin directory refuses "wp" anywhere in a plugin's name or slug, so
 * it was renamed before submission. Options keep their admindra_mcp_
 * prefix, so settings carry over. The class
 * names are new on purpose: if both folders are installed, neither can
 * redeclare the other's classes, and this one stays idle until the old one
 * is deactivated (see the guard below).
 *
 * @package AdMindra_MCP
