` 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](https://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=
`
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`
* **Correct HTTP caching** — `Vary: Accept` ensures CDNs cache HTML and Markdown
versions separately
#### Response headers
* `Content-Type: text/markdown; charset=utf-8`
* `Content-Language: it` (or detected language)
* `Vary: Accept`
* `X-Markdown-Tokens: 725`
* `Content-Signal: ai-train=yes, search=yes, ai-input=yes`
* `Link: ; rel="alternate"; hreflang="en"` (when translations available)
#### Multilingual plugin support
* **WPML** — reads language and available translations automatically
* **Polylang** — reads language and links to translated post IDs
* **TranslatePress** — reads `trp_language` post meta
* **Manual** — configure primary language and additional languages in Settings
Mescio for Agents
#### REST API
```
GET /wp-json/mescio-for-agents/v1/markdown?id=42

## FAQ
### Will this affect my site’s SEO or how Google crawls it?
No. The plugin only responds with Markdown when an HTTP client sends `Accept: text/
markdown`. Standard browsers and Googlebot never send this header, so they receive
the normal HTML page. The Markdown responses include `X-Robots-Tag: noindex` to
be safe.
### Does it work with the Gutenberg block editor?
Yes. The plugin applies WordPress’s `the_content` filter, which fully processes
Gutenberg blocks into HTML before conversion.
### Does it work with Elementor, Divi or other page builders?
Yes. The HTML cleaner aggressively strips layout wrapper elements, data attributes
and icon-only links produced by visual page builders, resulting in clean semantic
Markdown.
### Does it work without WooCommerce?
Yes. WooCommerce is completely optional. Without it, the plugin works normally for
posts and pages.
### Does it require WPML or Polylang?
No. Both are optional. Without them, Mescio for Agents detects the site language
from the WordPress locale setting. You can also configure languages manually in
Settings Mescio for Agents.
### Can I add custom post types?
Yes, either from the settings page or via the `mescio_enabled_post_types` filter:
```
add_filter( 'mescio_enabled_post_types', function( $types ) {
$types[] = 'my_cpt';
return $types;
});
```
### Is there a “powered by” link added to my site?
No. The plugin adds no frontend links, scripts or styles to your site.

## Caathetan Owahan
#### 1.6.9
* Improved: Link headers (RFC 8288) now use `wp_headers` filter instead of `send_headers`
action — more reliable with caching plugins and CDN/reverse-proxy setups
* Added: `api-catalog` Link header pointing to `/.well-known/api-catalog` (RFC
9727)
* Added: `service-doc` Link header alongside `service-desc` — covers more agent/
checker implementations
* Fixed: OpenAPI `service-desc` now uses correct media type `application/vnd.oai.
openapi+json` instead of generic `application/json`
#### 1.6.8
* New: Link headers (RFC 8288) for agent discovery — emitted on homepage, Markdown
responses, REST `/markdown` endpoint, and `llms.txt` / `llms-full.txt`
* Links advertise: `llms.txt` (`rel="describedby"`), `llms-full.txt` (`rel="describedby"`),
OpenAPI schema (`rel="service-desc"`), `agents.txt` (`rel="agent-policy"`)
* Markdown and REST responses also include a self-referencing `rel="canonical"`
Link header
* All links filterable via `mescio_link_headers` filter; feature disableable via`
mescio_link_headers_enabled` filter
#### 1.6.7
* Fix: resolved option group mismatch in Content Signals introduced in 1.6.5 —
settings now save and load correctly across all WordPress versions
* Hardened Content Signals sanitization to strictly allow only ‘yes’ or ‘no’ values
per signal key
#### 1.6.6
* Fix: Content Signals settings were not saved correctly — `register_setting()`
used wrong option group (`mescio_for_agents` instead of `mescio_settings`), causing
robots.txt and HTTP headers to always emit default values regardless of admin
configuration
#### 1.6.5
* Security: added two-layer burst protection to rate limiter — IPs sending more
than 20 req/5s are auto-blocked for 10 minutes; blocked IPs rejected with a single
transient read before any WordPress processing
* All burst thresholds filterable: `mescio_burst_limit`, `mescio_burst_window`,`
mescio_block_duration`
* REST 429 responses now include `Retry-After`, `X-RateLimit-Remaining`, `X-RateLimit-
Reset` headers
* New: Content Signals support (draft-romm-aipref-contentsignals) — site owners
can now declare AI usage preferences
* Content Signals published in `robots.txt` via `Content-Signal:` directive and
in all Markdown/REST response headers
* Default values: `ai-train=no, search=yes, ai-input=yes` (conservative — protects
owners who install without reading docs)
* Configurable from Settings Mescio for Agents with live preview
* Filterable by developers via `mescio_content_signals` filter
* Replaced hardcoded `Content-Signal: ai-train=yes` header with dynamic value from
settings
#### 1.6.3
* Fix: shortcode builder tags (WPBakery, WoodMart, ecc.) rimossi anche dagli excerpt
nel llms.txt index
* Fix: llms.txt ora serve titoli, excerpt e permalink nella lingua corretta su
siti multilingua (WPML/Polylang)
* Fix: llms-full.txt ora serve il contenuto completo dei post nella lingua corretta(
WPML/Polylang)
#### 1.6.1
* Fixed 404 on multilingual sites using WPML or Polylang: `llms.txt` and `llms-
full.txt` now resolve correctly under language-prefixed URLs (e.g. `/it/llms.
txt`, `/en/llms-full.txt`)
* Added `parse_request` early intercept (priority 1) as fallback for language plugins
that rewrite REQUEST_URI before WordPress rewrite rules run
* Added rewrite rule variant matching `/xx/llms.txt` and `/xx-XX/llms.txt` patterns
#### 1.6.0
* Added rate limiting: per-IP request throttling on all endpoints via WordPress
transients
* `llms-full.txt` limited to 10 req/60s, REST search to 20, other REST to 30, default
to 60
* Returns 429 Too Many Requests with `Retry-After` header when limit exceeded
* Respects Cloudflare, nginx and standard `X-Forwarded-For` proxy headers
* Added sensitive meta key filter: fields containing `password`, `token`, `email`,`
phone`, `iban` and similar patterns are never exposed in Markdown front matter
* Both rate limiting and sensitive key filter are filterable by developers
#### 1.5.0
* Added automatic custom fields support in Markdown front matter
* If ACF is active, uses `get_fields()` with label-keyed, typed values; nested
groups and repeaters flattened to dot notation (e.g. `group.field`)
* Without ACF, exposes plain post meta — skipping internal keys (`_` prefix), serialized
data, JSON blobs and known plugin internals
* Added `mescio_custom_meta` filter for developer overrides
#### 1.4.0
* Added `/agents.txt` endpoint following IETF draft-srijal-agents-policy-00
* SHA-256 hash computed automatically from directive content
* Configurable directives (path, ALLOW/DISALLOW, optional params) via admin settings
* Live preview of generated file with hash in settings page
* Default directives: `/ ALLOW`, `/wp-admin DISALLOW`, `/wp-login.php DISALLOW`
* Added `/agents.txt` link in Quick Links table
#### 1.3.0
* Refactored monolith into modular architecture (6 separate class files)
* Added REST endpoint `/wp-json/mescio-for-agents/v1/context` — site metadata +
llms.txt in JSON for MCP servers
* Added REST endpoint `/wp-json/mescio-for-agents/v1/search` — full-text search
with Markdown output
* Added REST endpoint `/wp-json/mescio-for-agents/v1/page` — page by slug or ID
* Added REST endpoint `/wp-json/mescio-for-agents/v1/openapi` — OpenAPI 3.1 schema
* Added `llms-full.txt` pagination via `?limit=N&offset=N` with `X-LLMS-Next` header
* Improved caching: real `Last-Modified` from content timestamp, `ETag` from body
hash, full 304 support
* Fixed excess blank lines in Markdown output from Elementor and other page builders
* Expanded admin API Examples panel with 8 tabs and copy buttons
#### 1.2.0
* Added `/llms.txt` endpoint — auto-generated site index in the llmstxt.org standard
format
* Added `/llms-full.txt` endpoint — full site content in a single Markdown file
for RAG pipelines
* Products in `llms.txt` grouped by WooCommerce category with price and stock status
* Added `mescio_llms_txt_posts_limit`, `mescio_llms_txt_products_limit`, `mescio_llms_full_txt_limit`
filters
* Added flush rewrite rules on plugin activation/deactivation
* Added `/llms.txt` and `/llms-full.txt` clickable links in the settings test panel
