<p>The MCP Servers plugin enables WordPress to expose “abilities” – standardized functions that AI agents (such as Claude, Mistral, or ChatGPT) can invoke.</p>
<p>These abilities allow plugins and themes to describe their functionalities and required parameters in a structured way, facilitating seamless interaction with AI agents via the MCP (Model Context Protocol).</p>
<h4>Use Cases</h4>
<ul>
<li>A newsletter plugin can expose abilities to manage subscribers or newsletters.</li>
<li>A form manager can provide abilities to handle forms or process submissions.</li>
<li>No limits: Any functionality can be exposed and utilized by AI agents.</li>
</ul>
<h4>Creating a server</h4>
<p>Go to the “Servers” page and add a server. By default, a new MCP server does not expose any abilities. You can:</p>
<ul>
<li>Select one or more ability categories.</li>
<li>Choose individual abilities to expose.</li>
</ul>
<h4>Best Practices</h4>
<ul>
<li>Avoid exposing all abilities: This can overwhelm AI agents and lead to overlapping functionalities.</li>
<li>Limit abilities to those necessary for your current workflow.</li>
<li>Create multiple MCP servers to enable only the tools required for specific tasks on the agent side.</li>
</ul>
<h4>Connecting to a server</h4>
<p>AI agents can connect to your MCP server(s) in several ways. The simplest method is:</p>
<ul>
<li>Create an administrator user named “mcp”.</li>
<li>Generate an application password for this user in the WordPress dashboard.</li>
<li>Use Basic Authentication with the mcp username and the application password to set up the connection from the AI agent.</li>
</ul>
<h4>Note on Authentication</h4>
<p>Not all AI agents support Basic Authentication. For example, Claude requires OAuth2.</p>
<p>To enable OAuth2, install a compatible plugin (e.g., WP OAuth Server).</p>

</ul>
<p>The AI Experiments plugin contains the “Ability explorer” a very useful tool.</p>
<h4>Tech details</h4>
<p>The plugin uses the WP MCP Adapter library or the MCP Adapter plugin (if installed), with priority given to the latter.</p>
<p>Once the Adapter plugin is officially available, it will be added as a dependency, and the PHP library will be removed.</p>
<h4>Warning</h4>
<p>Abilities are registered an implemented by plugins and themes: check carefully what they do before exposing!</p>
<p>And be aware that permission checks are up to the single ability.</p>

<p><strong>All Sources Images</strong> helps WordPress users search Pixabay and Unsplash images, download Pixabay photos or Unsplash photos, and turn them into a featured image, inline content image, or bulk image workflow without leaving the editor.</p>
<p>If your goal is to find a fast WordPress Pixabay plugin or an Unsplash plugin, this plugin is built for that use case: search Pixabay from the Media Library, browse Unsplash inside Gutenberg or Elementor, and assign a featured image automatically when you publish.</p>
<p>Beyond Pixabay and Unsplash, the plugin also supports Pexels, Openverse, Flickr, GIPHY, YouTube thumbnails, and AI image generation with DALL·E, Stability AI, Gemini, Replicate, and Cloudflare Workers AI.</p>
<h4>Main Features</h4>
<ul>
<li>Search Pixabay, Unsplash, Pexels, Flickr, Openverse, GIPHY, and more stock photo providers</li>
<li>Generate images using supported AI providers when Pixabay or Unsplash are not enough for a specific post</li>
<li>Set images as featured images</li>
<li>Set a featured image automatically on publish or in bulk workflows</li>
<li>Insert Pixabay, Unsplash, or AI images inside post content</li>
<li>Bulk-generate featured images for multiple posts</li>
<li>Gutenberg block for manual Pixabay and Unsplash image search and insertion</li>
<li>Elementor widget for Pixabay and Unsplash image search and insertion</li>
<li>Automatic featured image generation on post publish (optional)</li>
<li>Keyword extraction from title, content, tags, and categories</li>
<li>Logging for troubleshooting</li>
<li>REST API support</li>
<li>WordPress Abilities API support for MCP-compatible clients (WordPress 6.9+)</li>
</ul>

<h4>Supported Image Sources</h4>
<p><strong>AI Generation</strong><br />
* OpenAI (DALL·E)<br />
* Stability AI<br />
* Google Gemini<br />
* Replicate<br />
* Cloudflare Workers AI</p>
<p><strong>Stock / Search Sources</strong><br />
* Pixabay<br />
* Unsplash<br />
* Pexels<br />
* Flickr<br />
* Openverse<br />
* GIPHY<br />
* YouTube thumbnails</p>
<h4>How It Works</h4>
<p>The plugin can work in two ways depending on the source:</p>
<ol>
<li>
<p><strong>Direct API mode</strong><br />
You add your own API keys for supported providers and the plugin connects directly to those services.</p>
</li>
<li>
<p><strong>Developer proxy mode (optional, for some stock sources)</strong><br />
Some stock image searches can work without your own API key through an optional developer-operated proxy service. In that case, the search keywords are sent to the developer proxy, which forwards the request to the relevant image provider and returns the results.</p>
</li>
</ol>
<p>AI image generation services generally require your own API keys.</p>
<h4>Why publishers use it for featured images</h4>
<p>Many site owners search for a WordPress Pixabay plugin or a WordPress Unsplash plugin because their main goal is simple: find a relevant featured image fast. This plugin makes Pixabay and Unsplash part of the normal WordPress editorial workflow, so editors can search, compare, download, and assign a featured image without jumping between browser tabs.</p>
<p>The same setup can also automate featured image generation on publish, bulk generation for archives, and AI fallback when a Pixabay or Unsplash result is not the best match. That combination is useful for blogs, news sites, affiliate sites, magazines, and content teams publishing at scale.</p>
<h4>Typical Use Cases</h4>
<ul>
<li>Automatically find a featured image from Pixabay or Unsplash for a blog post</li>
<li>Insert a Pixabay or Unsplash image after a selected paragraph</li>
<li>Search Pixabay and Unsplash directly from the Media Library</li>
<li>Use the Gutenberg block to manually insert Pixabay or Unsplash images in content</li>
<li>Use the Elementor widget to search and display Pixabay or Unsplash images</li>
<li>Bulk-process many posts with Pixabay, Unsplash, or AI fallback</li>
</ul>
<h4>AI Agent Integration</h4>
<p>With WordPress 6.9+, AI agents can interact with this plugin through the WordPress Abilities API and MCP-compatible tools.</p>
<p>Available abilities include:</p>
<ul>
<li><code>allsi/search-image</code></li>
<li><code>allsi/set-featured-image</code></li>
<li><code>allsi/auto-generate-for-post</code></li>
<li><code>allsi/insert-image-in-content</code></li>
<li><code>allsi/generate-ai-image</code></li>
</ul>
<p>This allows compatible assistants to help find, generate, and assign images to posts.</p>
<h3>Usage</h3>
<p>There are several ways to use the plugin:</p>
<h4>1. Media Library</h4>
<ol>
<li>Go to <strong>Media > Add New</strong> or open a media picker</li>
<li>Open the <strong>All Sources Images</strong> tab</li>
<li>Search for images</li>
<li>Download the selected image into your Media Library</li>
</ol>
<h4>2. Gutenberg Block</h4>
<ol>
<li>In the Block Editor, add the <strong>ASI Images</strong> block</li>
<li>Search images from supported sources</li>
<li>Select and insert the image into the post</li>
</ol>
<h4>3. Elementor Widget</h4>
<ol>
<li>In Elementor, add the <strong>ASI Image</strong> widget</li>
<li>Open the image explorer</li>
<li>Search and select an image source</li>
<li>Insert the image into the page</li>
</ol>
<h4>4. Post Image Generation</h4>
<ol>
<li>Open a post or page</li>
<li>Use the image generation tools from the plugin interface</li>
<li>Generate or retrieve an image</li>
<li>Set it as featured image or insert it into content</li>
</ol>
<h4>5. Bulk Generation</h4>
<ol>
<li>Go to the bulk generation interface</li>
<li>Select one or more posts</li>
<li>Run the generation process</li>
<li>The plugin processes the configured image blocks for each selected post</li>
</ol>
<h3>Configuration</h3>
<p>Configuration depends on the providers you want to use.</p>
<h4>Stock image sources</h4>
<p>Pixabay and Unsplash, along with some other stock image providers, can work either:</p>
<ul>
<li>through the optional developer proxy, or</li>
<li>through your own API keys, where supported</li>
</ul>
<p>Using your own API keys for Pixabay, Unsplash, and other supported sources may provide direct connections and provider-specific rate limits.</p>
<h4>AI image generation sources</h4>
<p>AI services generally require your own API keys.</p>
<p>To configure providers:</p>
<ol>
<li>Go to <strong>All Sources Images</strong></li>
<li>Open the <strong>Image Banks</strong> tab</li>
<li>Add your API keys for the providers you want to use</li>
<li>Save the settings</li>
</ol>
<h3>External Services</h3>
<p>This plugin connects to external third-party services to search, retrieve, or generate images.</p>
<p>Depending on the provider and feature used, the plugin may send search keywords, prompts, post titles, selected text, or video URLs.</p>
<h4>Important</h4>
<ul>
<li>The plugin can connect either directly to third-party providers or, for some supported stock sources, through an optional developer-operated proxy service.</li>
<li>The optional proxy is used only for supported stock-source requests.</li>
<li>AI image generation services generally require your own API keys.</li>
<li>Please review the terms and privacy policies of each external service before use.</li>
</ul>
<h3>Plugin Developer Service</h3>
<h4>All Sources Images Proxy (optional)</h4>
<p>For some supported stock image sources, the plugin can use an optional proxy service operated by the plugin developer.</p>
<p>When this proxy path is used:</p>
<ul>
<li>search keywords are sent to the developer proxy</li>
<li>the developer proxy forwards the request to the relevant image provider</li>
<li>the proxy returns the search results to your site</li>
</ul>
<p>This proxy exists only to perform the remote request to the external provider on behalf of the site.</p>
