About this plugin
ModelGain Multilingual Abilities makes multilingual content audits available as four read-only WordPress abilities. It works with an existing Polylang installation and does not translate text, publish content, modify language assignments or change translation relationships.
- modelgain-multilingual/list-languages: list configured language slugs and the default language.
- modelgain-multilingual/find-missing-translations: find articles in a selected source language without a linked target-language translation.
- modelgain-multilingual/audit-language-coverage: report linked, unpublished, absent, inaccessible and invalid translation counts for a bounded page of source articles.
- modelgain-multilingual/check-translation-links: check public Polylang translation maps for verifiable structural inconsistencies.
All content operations specify the source language and Polylang-enabled post type. The maximum source page size is 100. Results contain IDs, status and URLs, never article bodies or the contents of translations.
Pagination and scope: limit and offset refer to source-language posts scanned, not the number of missing translations returned. A page of source posts may contain zero missing translations while has_more is true. Iterate using next_offset until has_more is false.
Coverage counters are page-level, not unqualified site-wide totals. Results may change when editors modify content between pages.
The initial version is read-only and does not implement any AI model integration, machine translation service, chatbot, background scan or standalone MCP server. The official WordPress MCP Adapter can optionally transport abilities after a site owner enables external exposure.
Access and permissions
External REST/MCP visibility is disabled on a clean installation. Local WordPress abilities are available when Polylang and the WordPress Abilities API are active.
Only authenticated administrators with manage_options may execute the operations. Posts are inspected only when the current user can edit the post. Enabling the external REST interface does not grant those permissions to anonymous visitors.
To enable REST discovery, navigate to Tools > Multilingual Abilities, enable External REST exposure, and save settings. External clients must use WordPress-supported authentication and an authorized identity. Leave external exposure disabled if no integration needs it.
Polylang remains responsible for all language and translation data. This plugin does not contact third-party services or collect telemetry. The plugin stores only its optional REST exposure preference; uninstalling it removes that preference without deleting translations.
Requirements
- WordPress 6.9 or later and PHP 7.4 or later.
- An active Polylang installation with configured languages.
- A supported Polylang-translated post type (for example, posts or pages if enabled).
The plugin does not require Polylang Pro or an external AI subscription. It is an independent integration and is not affiliated with Polylang.
