The MCP Servers plugin enables WordPress to expose “abilities” – standardized functions that AI agents (such as Claude, Mistral, or ChatGPT) can invoke.
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).
<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>
Go to the “Servers” page and add a server. By default, a new MCP server does not expose any abilities. You can:
<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>
AI agents can connect to your MCP server(s) in several ways. The simplest method is:
<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>
Not all AI agents support Basic Authentication. For example, Claude requires OAuth2.
To enable OAuth2, install a compatible plugin (e.g., WP OAuth Server).

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

Mescio

WebMCP Bridge exposes your WordPress (and WooCommerce) functionality as <a href="https://github.com/webmcp/webmcp-spec" rel="nofollow ugc">WebMCP</a> tools that AI agents can discover and invoke directly in the browser.
Once installed, your site automatically becomes “agent-friendly”:
<ul>
<li>AI agents can search posts, pages, and custom post types</li>
<li>AI agents can browse products, manage the cart, apply coupons (WooCommerce)</li>
<li>AI agents can read navigation menus and site metadata</li>
<li>Developers can register custom tools in minutes via a simple PHP API</li>
</ul>
What is WebMCP?
WebMCP is a new browser-native protocol (currently in Chrome Early Preview) that lets web apps expose their functionality as structured “tools” that AI agents can invoke — without needing to screenshot or parse HTML. Think of your website as an MCP server running entirely client-side.
How it works
<ol>
<li>Install and activate the plugin</li>
<li>Enable the features you want from Settings → WebMCP Bridge</li>
<li>Your tool manifest is immediately available at <code>/wp-json/webmcp-bridge/v1/manifest</code></li>
<li>AI agents (or any JavaScript code) can call your tools via REST API or the native browser WebMCP API</li>
</ol>
Included tools
Core:
<ul>
<li><code>search_posts</code> — Search posts, pages, or custom post types</li>
<li><code>get_post</code> — Retrieve a single post by ID or slug</li>
<li><code>get_menu</code> — Return navigation menu items</li>
<li><code>get_categories</code> — List taxonomy terms</li>
<li><code>get_site_info</code> — Site name, description, URL, language</li>
<li><code>submit_contact_form</code> — Contact Form 7 integration</li>
</ul>
WooCommerce (requires WooCommerce plugin):
<ul>
<li><code>woo_search_products</code> — Search by keyword, category, price range</li>
<li><code>woo_get_product</code> — Full product details including attributes</li>
<li><code>woo_add_to_cart</code> — Add a product to the cart</li>
<li><code>woo_get_cart</code> — Current cart contents and totals</li>
<li><code>woo_remove_from_cart</code> — Remove an item by cart key</li>
<li><code>woo_apply_coupon</code> — Apply a coupon code</li>
<li><code>woo_get_checkout_fields</code> — Return checkout field schema</li>
<li><code>woo_get_product_categories</code> — List all product categories</li>
</ul>
Even more powerful with Mescio for Agents
WebMCP Bridge integrates automatically with the Mescio for Agents plugin. When both plugins are active, two additional tools are unlocked:
<ul>
<li><code>get_markdown_content</code> — Returns any post or page as clean Markdown, the format AI models consume most efficiently. Instead of raw HTML, agents receive structured, token-optimized content ready for reasoning and summarization.</li>
<li><code>get_llms_txt</code> — Exposes the site-wide <code>llms.txt</code> context document (index or full variant), giving agents an instant, structured overview of what the site is about, who it is for, and what content is available — before they even start searching.</li>
</ul>
Together, the two plugins turn your WordPress site into a fully AI-native content source: WebMCP Bridge handles the tool layer (what agents can do), while Mescio for Agents handles the content layer (what agents can read and understand).
Privacy
This plugin does not collect, store, or transmit any user data to external servers. All tool execution happens locally within your WordPress installation. No telemetry, no phone-home, no external API calls.

WebMCP Bridge

Make your WordPress site natively AI-agent friendly via the WebMCP protocol — no backend server required.
