Model Context Protocol server for CiviCRM — AuthX-first, schema-introspected, write-gated.

<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).
The author’s registry entry marks them as required.
Optional settings from the registry entry, left out of the block above:
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).
