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.

AgentGate

Agentgate for WebMCP is a zero-configuration plugin that makes your published content available to AI agents through the WebMCP browser standard. Activate it on any HTTPS-enabled WordPress 6.9 site and three read-only tools become available instantly.
<h4>What agents can do</h4>
Agents visiting your site in a supported browser can:
<ul>
<li>Search your published posts by keyword and receive titles, excerpts, and links.</li>
<li>Look up a single post by its ID or slug to get the full text, categories, and tags.</li>
<li>Retrieve a complete list of your site’s categories with descriptions and post counts.</li>
</ul>
No content is modified. Agents see the same public information as any visitor.
<h4>Under the hood</h4>
A small deferred script checks whether the browser supports <code>navigator.modelContext</code>. If it does, the plugin fetches the available tool definitions from a local REST endpoint and registers them. Each tool invocation is processed server-side, sanitized, and returned as structured JSON. Results are cached in the browser for 24 hours to keep requests low.
Unsupported browsers simply ignore the script — nothing breaks, nothing logs.
