SM Agent Kit

AI agents don’t browse the web the way humans do. They request structured data, negotiate content formats, and look for standardised discovery endpoints. SM Agent Kit adds all of this to any WordPress site automatically, with a clean admin UI and zero hardcoding.

Markdown negotiation

When an agent sends a request with Accept: text/markdown, your site returns the post or page as clean markdown instead of HTML, with a Content-Type: text/markdown header and x-markdown-tokens: 1. Human visitors never notice a thing.

Content signals

Adds a Content-Signal directive to your robots.txt declaring your preferences for AI training, search indexing, and agent input. Supports the ai-train, search, and ai-input fields per the emerging Content Signals standard.

Well-known endpoints

Serves four auto-generated JSON files that agent frameworks and crawlers look for:

• /.well-known/api-catalog – lists your REST API and sitemap endpoints (RFC 9727)
• /.well-known/mcp/server-card.json – declares MCP server capabilities (SEP-1649)
• /.well-known/agent-skills/index.json – lists what your site can do as an agent-callable service
• /.well-known/agentic-commerce/product-feed.json – read-only product feed for agent shopping tools, built from WooCommerce data

All four endpoints build dynamically from your WordPress data including site name, tagline, registered post types, REST API root, and product catalog with no hardcoding required. Install on multiple sites and each one generates correct, site-specific output automatically.

Agentic commerce

If WooCommerce is active, SM Agent Kit can publish a read-only feed of your published products: name, price, currency, availability, SKU, and URL. This makes your catalog discoverable to AI shopping agents without exposing any checkout or payment functionality. If WooCommerce is not installed, this section is automatically marked as not applicable.

The plugin also publishes UCP and ACP protocol manifests declaring your commerce capabilities to AI shopping agents, and a stubbed checkout endpoint that responds clearly when checkout is not available. No payment processing is implemented in this plugin. Live agent checkout requires a separate payment provider integration.

Settings UI

SM Agent Kit adds its own item to the WordPress admin sidebar. Every feature is togglable. Tooltips explain each field. A permalink reminder appears after every save so you never miss the rewrite flush.
