[WordPress] 外掛分享： Mescio for Agents

WordPress 6.0+ PHP 8.0+ v1.7.9 上架：2026-03-05

wrappers, navigation bars and script tags that carry zero semantic value. This blog post you are reading takes 16,180 tokens in HTML and 3,150 tokens in Markdown. That is an 80% reduction.
Markdown has become the lingua franca for AI systems. Mescio for Agents lets your site speak it natively, at zero cost to your human visitors.
How it works
When an HTTP client sends a request with Accept: text/markdown, Mescio for Agents intercepts the WordPress request lifecycle before any template is rendered, converts the post content to clean Markdown, and returns it with the correct Content-Type: text/markdown header.
curl https://yoursite.com/your-post/ \
-H "Accept: text/markdown"

Features

Zero configuration — works out of the box on any singular post, page or custom post type
/llms.txt endpoint — auto-generated index of all your content in the llmstxt.org standard format, so AI agents can discover what’s on your site
/llms-full.txt endpoint — full site content in a single Markdown file, ready for RAG pipelines
WooCommerce support — product pages include price, SKU, stock status, rating, attributes and gallery; products are grouped by category in llms.txt
Hide storefront pages — Cart, Checkout, My Account, Wishlist and payment-result pages stay out of llms.txt automatically; hide any other page from the metabox or a settings ID/URL list
YAML front matter — every document includes structured metadata (title, description, URL, date, categories, tags, featured image)
Multilingual — detects language via WPML, Polylang, TranslatePress or WordPress locale; emits Content-Language and Link: rel=alternate headers
REST API endpoint — /wp-json/mescio-for-agents/v1/markdown?id= or ?url= Page builder cleanup — aggressively strips Elementor, Divi, WPBakery and Beaver Builder layout noise
Token count header — X-Markdown-Tokens tells AI pipelines how large the document is before processing
Content Signals — emits Content-Signal: ai-train=yes, search=yes, ai-input=yes
Cache-safe Markdown — permalink content negotiation is skipped when a full-page cache is detected (LiteSpeed, WP Rocket, …) so Markdown cannot replace the HTML page in cache; agents use the REST alternate instead

Optional companion: WebMCP Bridge
Mescio for Agents is the content layer (what agents can read). WebMCP Bridge — same author, also free — is the tool layer (what agents can do): search, menus, and WooCommerce cart actions, without scraping HTML.
When both plugins are active, WebMCP automatically unlocks get_markdown_content and get_llms_txt. Mescio for Agents works fully on its own; WebMCP is optional.
