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>Quick Start</h3>

<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.

Great WPO resource

Muy útil para gestión del día a día de las imágenes

Tus archivos de imágenes bajo control

Manage image file size, alt text and AI-powered media audits in your WordPress Media Library to improve performance, accessibility and SEO.

AI agents — tools like ChatGPT, Claude, Copilot, and the growing ecosystem of autonomous AI systems — are increasingly being pointed at websites to gather information, interact with APIs, and perform tasks on behalf of users. For a site to work well with these agents, it needs to speak the right language: publishing structured discovery files, declaring its capabilities, and responding to agent-specific requests in the right format.
KP Agent Ready handles all of that for your WordPress site. It implements the current set of agent-readiness standards and the broader AI agent ecosystem — without requiring you to manually create files, edit server configs, or touch a line of code. Everything is managed from a dedicated settings page in the WordPress admin.
<h4>What It Does</h4>
RFC 8288 Link Response Headers 
Every response your site sends will include <code>Link</code> headers pointing agents to your API catalog, agent skills index, and MCP server card. This is how agents find your discovery documents without having to guess URLs.
API Catalog — <code>/.well-known/api-catalog</code> 
Publishes a machine-readable catalog of your site’s APIs in the <code>application/linkset+json</code> format defined by RFC 9727. Each entry in the catalog can point to an OpenAPI specification, human-readable documentation, and a health/status endpoint. If you have not configured any entries yet, the plugin serves a sensible fallback automatically so the endpoint is always valid.
Agent Skills Index — <code>/.well-known/agent-skills/index.json</code> 
Publishes a skills discovery index per the Agent Skills Discovery RFC v0.2.0. This tells agents what your site can do — search your blog, browse your portfolio, submit a contact form, and so on.
Skills are built from three sources:
<ul>
<li>Blog articles — a search skill and a browse skill, toggled with a single switch</li>
<li>Custom post types — any public CPT registered on your site appears as a checkbox; tick it and it gets a browse skill pointing to its archive</li>
<li>Manual entries — define any additional skill with a name, type, description, URL, and an optional sha256 digest</li>
</ul>
MCP Server Card — <code>/.well-known/mcp/server-card.json</code> 
Publishes an MCP Server Card (SEP-1649) identifying your site to Model Context Protocol clients. Configurable name, version, description, transport endpoint, and a capability list. If you do not have an MCP server running yet, just leave the transport blank — the card is still valid and useful for discovery.
OAuth / OIDC Discovery — <code>/.well-known/openid-configuration</code> or <code>/.well-known/oauth-authorization-server</code> 
If your site exposes protected APIs that require authentication, this feature publishes the discovery metadata agents need to authenticate. Supports both OpenID Connect Discovery 1.0 and RFC 8414. Disabled by default — only enable it if you have the infrastructure in place.
OAuth Protected Resource Metadata — <code>/.well-known/oauth-protected-resource</code> 
Complements the OAuth/OIDC feature by publishing RFC 9728 Protected Resource Metadata. Disabled by default.
robots.txt Content Signals 
Appends Content Signals directives to your <code>robots.txt</code> file, declaring your preferences for how AI systems may use your content:
<ul>
<li>ai-train — whether AI companies may use your content to train models</li>
<li>search — whether search engines may index your content</li>
<li>ai-input — whether AI retrieval systems (RAG) may use your content as input</li>
</ul>
Markdown Negotiation 
When an AI agent sends a request with the <code>Accept: text/markdown</code> header, the plugin intercepts the response for singular posts and pages and returns a clean Markdown version of the content. Regular browser requests are completely unaffected.
WebMCP 
Injects a small JavaScript snippet into your page footer that calls <code>navigator.modelContext.provideContext()</code>, exposing your site’s key actions as tools to AI agents running in the browser. Built-in tools include blog search, portfolio navigation, and contact page navigation — each individually toggleable.
llms.txt and llms-full.txt 
Generates physical <code>/llms.txt</code> and <code>/llms-full.txt</code> files in your WordPress web root per the <a href="https://llmstxt.org" rel="nofollow ugc">llmstxt.org</a> specification. These files give AI systems a structured, readable index of your site’s content — who you are, what pages exist, and what your posts are about.
<pre><code>llms.txt contains your site header and a clean list of links by content type. `llms-full.txt` contains the same structure but expands each entry with an excerpt or truncated content block so AI systems can understand the content without fetching every URL.
</code></pre>
Files are regenerated automatically when posts are published, unpublished, or trashed, and whenever settings are saved. A manual Regenerate button is available in the llms.txt settings tab. If your host prevents direct file writes, the generated content is displayed in the admin as a copyable textarea so you can create the files manually.
Configurable options include a custom intro block, toggling pages and posts independently, selecting additional custom post types, setting the excerpt word limit for <code>llms-full.txt</code>, and defining optional additional links that appear under an <code>## Optional</code> section in both files.
<h4>Developer Filters</h4>
Two filters let themes and other plugins extend the plugin’s output without touching settings:
<pre><code>kp_agent_skills — add entries to the agent skills index:

add_filter( 'kp_agent_skills', function ( array $skills ): array {
 $skills[] = [
 'name' => 'my-skill',
 'type' => 'api',
 'description' => 'Does something useful.',
 'url' => 'https://yoursite.com/api/endpoint',
 ];
 return $skills;
} );

kp_webmcp_tools — add tools to the WebMCP context:

add_filter( 'kp_webmcp_tools', function ( array $tools ): array {
 // $tools is the PHP array that becomes the JS tools array
 return $tools;
} );
</code></pre>
