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
- Install and activate the plugin
- Enable the features you want from Settings → WebMCP Bridge
- Your tool manifest is immediately available at
/wp-json/webmcp-bridge/v1/manifest - AI agents (or any JavaScript code) can call your tools via REST API or the native browser WebMCP API
Included tools
Core:
search_posts— Search posts, pages, or custom post typesget_post— Retrieve a single post by ID or slugget_menu— Return navigation menu itemsget_categories— List taxonomy termsget_site_info— Site name, description, URL, languagesubmit_contact_form— Contact Form 7 integration
WooCommerce (requires WooCommerce plugin):
woo_search_products— Search by keyword, category, price rangewoo_get_product— Full product details including attributeswoo_add_to_cart— Add a product to the cartwoo_get_cart— Current cart contents and totalswoo_remove_from_cart— Remove an item by cart keywoo_apply_coupon— Apply a coupon codewoo_get_checkout_fields— Return checkout field schemawoo_get_product_categories— List all product categories
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-widellms.txtcontext 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).
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.
No. The REST API endpoints work in every browser and environment. The native WebMCP browser registration is only available in Chrome Early Preview (experimental), but the fallback JavaScript API (window.webmcpBridgeTools) and REST endpoints work everywhere.
Yes. Read-only tools (search, get post, etc.) are publicly accessible by default, matching WordPress’s own REST API behaviour. Write-action tools (add to cart, apply coupon, submit form) require a valid WordPress nonce. You can customise which tools require authentication via the webmcp_bridge_protected_tools filter.
Yes. WooCommerce tools are automatically registered when WooCommerce is active and the WooCommerce option is enabled in settings.
When Mescio for Agents is active alongside WebMCP Bridge, two extra tools become available in the manifest: get_markdown_content (AI-optimized content format) and get_llms_txt (site-wide context document). These are detected automatically — no configuration needed.
Absolutely. Use the PHP API:
add_action( 'plugins_loaded', function() {
if ( ! class_exists( 'WebMCP_Bridge_Tool_Registry' ) ) return;
$registry = WebMCP_Bridge_Tool_Registry::instance();
$registry->register( 'my_tool', [
'description' => 'Does something useful.',
'group' => 'custom',
'inputSchema' => [ 'type' => 'object', 'properties' => [] ],
'callback' => function( $params ) { return [ 'ok' => true ]; },
] );
} );

You can also find it on the Settings → WebMCP Bridge page with a one-click copy button.
No. WebMCP Bridge does not collect, store, or send any data to external servers. See the Privacy section above.
