Mescio for Agents

Mescio for Agents makes your WordPress site AI-ready by silently serving posts, pages and WooCommerce products as clean, structured Markdown to any AI agent or LLM pipeline that requests it — using the standard HTTP Accept: text/markdown content negotiation header.

Human visitors using a browser are completely unaffected. Mescio for Agents only activates when an AI agent or crawler explicitly asks for Markdown.

Why Markdown?

Feeding raw HTML to an AI is expensive and noisy. A heading like ## About Us costs ~3 tokens in Markdown vs 12–15 tokens as HTML — before accounting for <div> 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
• 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=<post_id> or ?url=<permalink>
• 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

• Correct HTTP caching — Vary: Accept ensures CDNs cache HTML and Markdown versions separately
