Agentgate for WebMCP

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.

What agents can do

Agents visiting your site in a supported browser can:

• Search your published posts by keyword and receive titles, excerpts, and links.
• Look up a single post by its ID or slug to get the full text, categories, and tags.
• Retrieve a complete list of your site's categories with descriptions and post counts.

No content is modified. Agents see the same public information as any visitor.

Under the hood

A small deferred script checks whether the browser supports navigator.modelContext. 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.
