<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>

<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>
