Bubuku I Code

Bubuku Media Library helps content and marketing teams audit, monitor and optimize images in WordPress. Track file sizes, identify missing alt text, export reports, receive email summaries and connect AI assistants through MCP.
New in version 1.3.0: Bubuku Media Library includes an MCP Server that allows compatible AI assistants and developer tools to interact with your WordPress Media Library through a secure endpoint with role-based permissions.
You can:
<ul>
<li>Sort the Media Library by file size to easily identify large files.</li>
<li>Filter images that don’t have alternative text (alt text).</li>
<li>Use size-based filters (for example: optimal size, medium size, large size) to prioritize which images to optimize first.</li>
<li>Run a Bulk Action in the Media Library to calculate file sizes for existing uploads.</li>
<li>Export CSV reports including file size, format (MIME type), URL, alt text, image date, post title and post URL — ideal for audits or sharing with your team.</li>
<li>See a summary of your Media Library in a dashboard widget, including how many images are heavy or missing alt text.</li>
<li>Configure weekly or monthly email reports so you can monitor the optimization status of your images without logging into WordPress.</li>
<li>Connect MCP-compatible AI assistants to your Media Library using role-based permissions and configurable abilities.</li>
</ul>

<h3>AI & MCP Integration</h3>
Bubuku Media Library includes a built-in MCP Server that allows compatible AI assistants and development tools to securely interact with your WordPress Media Library.
Available MCP abilities include:
<ul>
<li>Listing media library attachments.</li>
<li>Reviewing image metadata and alt text coverage.</li>
<li>Exporting media audits to CSV.</li>
<li>Accessing media library summary metrics.</li>
<li>Triggering reports and diagnostics.</li>
<li>Managing media accessibility workflows.</li>
</ul>
Each ability can be enabled or disabled individually and restricted to a minimum WordPress role. This allows you to safely connect AI assistants like Claude Desktop, Codex, Cursor and other MCP-compatible clients to audit images, review missing alt text, generate reports and automate media management workflows, while keeping permissions under your control.
Typical use cases include:
<ul>
<li>Finding images without alt text.</li>
<li>Exporting media audits for content reviews.</li>
<li>Checking image size distribution.</li>
<li>Generating accessibility reports.</li>
<li>Integrating WordPress media workflows with AI assistants.</li>
<li>Automating repetitive media library review tasks.</li>
</ul>

<h3>Evaluate results</h3>
Recommended Tools 
– <a href="https://developer.chrome.com/docs/lighthouse/" rel="nofollow ugc">Lighthouse</a> (in Chrome DevTools) — Analyze image weight and format, as well as the use of alternative text (ALT). 
– <a href="https://www.webpagetest.org/" rel="nofollow ugc">WebPageTest</a> — Check how images affect real-world load times. 
– <a href="https://squoosh.app/" rel="nofollow ugc">Squoosh</a> — Compare visual quality and file size savings when optimizing images. 
– <a href="https://wave.webaim.org/" rel="nofollow ugc">WAVE Accessibility Tool</a> — Verify whether images are missing ALT attributes or if the alternative texts are descriptive.
Evaluation Guidelines 
– Identify images without ALT text or with excessive file size before running external tests. 
– After replacing large images or adding ALT text, repeat your evaluations to confirm improvements. 
– Evaluate both new and existing content — not only the most recent uploads. 
– Define an internal size limit (for example, 200 KB per image) and monitor it regularly. 
– Keep in mind that accessibility also affects SEO and overall user experience.

Bubuku Media Library

Una idea excelente, imprescindible en toda biblioteca de utilidades WPO para la correcta optimización de las webs.

Además, tiene aún algunas posibilidades de crecimiento como mostrar en el frontend a los usuarios conectados como admin las imágenes con un outline en caso de no tener definido el alt img:not([alt]) o quizás también leer el tamaño de las imágenes y mostrar los códigos de color según su peso, etc.

Como digo, una idea excelente, de un excelente programador.

Imprescindible en la biblioteca de utilidades WPO

A tool that helps outline big images or those that don't have the alt attribute. Very useful if you are improving a site's WPO or looking after better accessibility.

It does what it says, and it does it right.
