Markdown Content Negotiator for LLMs is a performance-optimized WordPress plugin designed to serve your website’s content in a format that AI agents and LLMs (Large Language Models) love: Clean Markdown.
Using standard HTTP Content Negotiation, the plugin detects when a request is made with the <code>Accept: text/markdown</code> header. Instead of serving the standard HTML theme, it returns a Markdown version of the post or page, complete with YAML Frontmatter, token estimation headers, and customizable content signals.
To ensure maximum performance and minimal server load, Markdown versions are pre-generated and cached using WP-Cron.
<h4>Key Features</h4>
<ul>
<li>Content Negotiation: Automatically switches to Markdown output when requested via the <code>Accept: text/markdown</code> header.</li>
<li>YAML Frontmatter: Includes metadata like Title, Date, Author, and Categories in a structured format.</li>
<li>Performance Tracking: Provides an <code>X-Markdown-Tokens</code> header using standard LLM token heuristics.</li>
<li>AI Metadata: Includes <code>X-Content-Signal</code> headers to help agents understand the nature of the document.</li>
<li>Background Caching: Uses WP-Cron to pre-calculate Markdown strings, ensuring zero latency during requests.</li>
<li>Admin Settings: Choose which post types to enable and configure global AI content signals.</li>
</ul>

Markdown for Agents and Statistics converts your WordPress content to Markdown and serves it 
to AI agents and language model tools that request it via HTTP content negotiation 
(<code>Accept: text/markdown</code>).
The Chancery Lane Project is a charity that helps organisations reduce emissions using the power of legal documents and processes. We’ve published this plugin as we believe that making content more legible for AI Agents makes a meaningful difference to their energy usage – not only by reducing the amount of tokens required (by up to 90% over HTML) to consume the content, but also minimising the server resources required to render, process and display pages at source.
How it works:
<ol>
<li>Posts and taxonomy archive pages are converted to Markdown and saved as static 
files on disk inside <code>wp-content/uploads/</code>.</li>
<li>When a visitor (or AI agent) requests a page with <code>Accept: text/markdown</code> in 
the HTTP headers, WordPress serves the pre-generated <code>.md</code> file directly — 
no page render required.</li>
<li>A <code><link rel="alternate" type="text/markdown"></code> tag is added to each page’s 
 so agents can discover Markdown versions automatically.</li>
</ol>
Features:
<ul>
<li>Content negotiation (<code>Accept: text/markdown</code>, <code>?output_format=md</code>, or known AI User-Agents)</li>
<li>Taxonomy archive support — category, tag, and custom taxonomy term pages served as Markdown post listings</li>
<li>Automatic Markdown generation on post save; taxonomy archives auto-update when any post in the term changes</li>
<li>AJAX bulk generation with live progress counter — no page timeouts on large sites</li>
<li>Per-post-type field configuration — choose which meta/ACF fields go in frontmatter or body</li>
<li>ACF support with dot notation for nested group fields (e.g. <code>group.subfield</code>)</li>
<li>Content fields option — use ACF fields as the body content instead of post_content</li>
<li>Manifest generation with content hashes and change tracking per post type</li>
<li>Incremental export — only re-export changed documents (<code>--incremental</code>)</li>
<li>Delta file (<code>changes.json</code>) for RAG system sync</li>
<li>Access statistics — logs AI agent requests with a dedicated stats admin page</li>
<li>Optional frontmatter fields — hierarchy (parent/ancestors/children IDs), author display name, root-relative featured image paths</li>
<li>Topics section — appends a <code>## Topics</code> section with linked taxonomy terms to the Markdown body</li>
<li>Export preview — preview generated Markdown inline in the post editor without writing to disk</li>
<li>WP-CLI commands: <code>generate</code>, <code>generate-taxonomies</code>, <code>prune-stats</code>, <code>status</code>, <code>delete</code></li>
<li>Fully unit-tested</li>
</ul>
