From 0ac9bbb373e14981609015ce5e14676a5afd1d31 Mon Sep 17 00:00:00 2001 From: Clayton Collie Date: Thu, 26 Mar 2026 11:41:44 +0100 Subject: [PATCH 1/3] (fix): Set PHPRC environment variable for WP-CLI execution WP-CLI commands executed through the MCP server fail on sites that use PHP extensions loaded via php.ini (e.g., memcache for object caching). The root cause is that PHPRC was not set in the child process environment, so PHP fell back to its compiled-in default ini path which lacks the site-specific extension configuration. Add findPhpIniDir() to resolve the site's php.ini directory from Local's run path, wire it through SiteConfig, and set PHPRC in buildWpCliEnv().
