WebMCP Bridge

WebMCP Bridge exposes your WordPress (and WooCommerce) functionality as WebMCP tools that AI agents can discover and invoke directly in the browser.

Once installed, your site automatically becomes “agent-friendly”:

• AI agents can search posts, pages, and custom post types
• AI agents can browse products, manage the cart, apply coupons (WooCommerce)
• AI agents can read navigation menus and site metadata
• Developers can register custom tools in minutes via a simple PHP API

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

1. Install and activate the plugin
2. Enable the features you want from Settings → WebMCP Bridge
3. Your tool manifest is immediately available at /wp-json/webmcp-bridge/v1/manifest
4. AI agents (or any JavaScript code) can call your tools via REST API or the native browser WebMCP API

• search_posts — Search posts, pages, or custom post types

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:

• get_markdown_content — 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.
• get_llms_txt — Exposes the site-wide llms.txt 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.

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).
