This one needs environment variables set before it will start: CIVICRM_BASE_URL (Base URL of the CiviCRM install, e.g. https://crm.example.org. No trailing slash.), CIVICRM_API_KEY (API key of the contact the server authenticates as. Keep it on a dedicated 'MCP Bot' contact with minimum permissions.), CIVICRM_CMS (CMS host: drupal, wordpress, standalone, or backdrop.), CIVICRM_SITE_KEY (Optional — only needed if the site enables the AuthX site-key guard.), CIVICRM_AUTH_MODE (authx (default, recommended) or legacy for pre-5.36 installs.), CIVICRM_ALLOW_WRITES (Set to 'true' to enable create / update / save / submit actions. Off by default.), CIVICRM_ALLOW_DELETES (Set to 'true' to enable delete / replace actions. Off by default.). The author declared them in the registry entry; get the values from the project itself.
