## Description
Increase your AI Visibility in ChatGPT, Claude, Gemini, Perplexity and other AI
search engines with 42A AI Visibility, powered by the Agentic Enablement Layer (
AEL). Monitor how your website appears in AI-generated answers, receive actionable
SEO and GEO recommendations, and enable built-in MCP support to help AI agents discover,
understand and interact with your content. Connect your free 42A account to unlock
advanced AI Visibility reports, competitor benchmarking, prompt-level analysis and
continuous optimization.
The Agentic Enablement Layer ships on activation, with zero configuration:
* **Markdown twin of every public page** – append `?format=markdown` to any URL(
or use the `.md` suffix, or send `Accept: text/markdown`) and get a clean markdown
version with YAML frontmatter. Every HTML page advertises it via `` and a `Link:` header.
* **llms.txt and llms-full.txt** – a spec-compliant llms.txt map of your key pages(
front page, navigation, recent posts, WooCommerce categories) with markdown links,
and a byte-capped llms-full.txt with full page content, served at your site root.
* **Public read-only MCP server** – a stateless Model Context Protocol (JSON-RPC
2.0, Streamable HTTP) endpoint at `/wp-json/42a/v1/mcp`, discoverable at `/.well-
known/mcp.json`, `/.well-known/mcp`, `/.well-known/mcp/server-card.json` and `/.
well-known/mcp-server` (all current draft discovery specs). Tools: `get_site_info`,`
search_content`, `get_page` (markdown), `list_recent_posts`, `list_categories`,
plus `search_products` and `get_product` when WooCommerce is active.
* **Local GEO vitals** – the Agent Layer tab in wp-admin self-tests all endpoints,
detects your sitemap and audits robots.txt against 87 known AI bots (training,
search and agentic tiers), and shows local agent-traffic counters.
* **Full GEO vitals report (optional, free account)** – connect a free 42A account
for the full ~30-check AI SEO / GEO report with per-check scores and fixes, refreshed
by 42A’s crawlers.
#### Why GEO / AI SEO matters
When someone asks an AI assistant “what’s the best X” or “does this store sell Y”,
the assistant answers from the sites it can actually read and query. Classic SEO
signals still matter, but AI search adds new ones: llms.txt, clean markdown content,
structured data, AI-crawler access in robots.txt, and machine-readable endpoints
like MCP. This plugin covers that layer for you – it’s SEO for the AI era.
#### How is this different from admin-automation MCP plugins?
Plugins like Automattic’s `wordpress-mcp` expose **authenticated admin automation**(
create posts, manage settings). 42A AEL is the opposite: a **zero-config, anonymous,
read-only public-content** MCP server – the same data any visitor sees, packaged
for agents – bundled with the whole agent layer (markdown, llms.txt, vitals). The
two can coexist; they use different routes.
#### Privacy first
The plugin makes **zero external requests** until you explicitly click “Connect
to 42A”. Agent-traffic counters are stored locally only. Telemetry reporting to
42A is opt-in and default off.
### External Services
This plugin can connect to the 42A API (`api.42a.ai`), operated by 42A. **No request
is ever made without explicit user action:**
* **Register** (`POST /api/v1/integrations/wordpress/register`) – only when you
click “Connect to 42A” or paste a pairing code. Sends: the pairing code, your
site URL, plugin version, WordPress version and the list of enabled agent-layer
capabilities.
* **Site status** (`GET /api/v1/integrations/wordpress/site`) and **Vitals** (`
GET /api/v1/integrations/wordpress/vitals`) – only while connected, when the
GEO Vitals tab loads or you click refresh. Sends: your site token.
* **Telemetry** (`POST /api/v1/integrations/wordpress/telemetry`) – only while
connected **and** after you enable the separate opt-in checkbox (default off).
Sends one daily aggregate: date, MCP request count, markdown hit count, llms.
txt hit count and per-tool call counts. Never any content, URLs or personal data.
* **Disconnect** (`POST /api/v1/integrations/wordpress/disconnect`) – when you
click Disconnect or uninstall the plugin, to revoke the site token.

## FAQ
### What is AI Visibility?
AI Visibility is how often and how prominently your website and brand appear in
AI-generated answers, in tools like ChatGPT, Claude, Gemini and Perplexity. Just
as SEO rankings measure your presence in classic search results, AI Visibility measures
whether AI assistants find, understand, mention and cite your site when users ask
relevant questions.
### What is GEO?
GEO (Generative Engine Optimization, also called AI SEO or LLM SEO) is the practice
of optimizing your site so generative AI engines can read, understand and cite it.
Classic SEO signals still matter, but GEO adds new ones: llms.txt, clean machine-
readable content, structured data, AI-crawler access in robots.txt and agent endpoints
like MCP. This plugin covers that technical layer for you and, with a free 42A account,
adds actionable GEO recommendations.
### How does MCP help AI agents?
MCP (Model Context Protocol) is an open standard that lets AI agents query a site
in a structured way instead of scraping HTML. This plugin runs a public, read-only
MCP server exposing tools like `search_content`, `get_page` and `list_recent_posts`(
plus product tools when WooCommerce is active), discoverable at `/.well-known/mcp.
json`. Agents that support MCP can find, understand and interact with your content
directly and reliably.
### Which AI search engines are supported?
The agent layer is built on open standards (markdown, llms.txt, MCP), so any AI
engine or agent can consume it – including ChatGPT, Claude, Gemini, Perplexity,
Copilot and AI crawlers such as GPTBot, ClaudeBot and PerplexityBot. The robots.
txt audit covers 87 known AI bots, and the 42A platform tracks your visibility across
the major AI assistants.
### Do I need a 42A account?
No. The entire agent layer (markdown, llms.txt, MCP server, local checks) works
forever without an account. A free 42A account adds the full GEO vitals report and
the AI Visibility dashboard: mentions, sentiment, share of voice, competitor benchmarking
and prompt-level analysis.
### Does it work with ChatGPT?
Yes. The markdown layer, llms.txt and the MCP server make your content easy for
ChatGPT and OpenAI’s crawlers (GPTBot, OAI-SearchBot) to read and cite, and the
robots.txt audit verifies they are not blocked. With a connected 42A account you
can also monitor how ChatGPT mentions your brand.
### Does it support Claude?
Yes. Claude and Anthropic’s crawlers (ClaudeBot) can consume your markdown pages,
llms.txt and the MCP server, and Claude is one of the assistants tracked in the
42A AI Visibility dashboard.
### Does it support Gemini?
Yes. Gemini and Google’s AI crawlers (Google-Extended) can read the same agent layer,
and Gemini is tracked in the 42A AI Visibility dashboard.
### Does it improve AI rankings?
No plugin can guarantee placement in AI answers. What this plugin does is remove
the technical barriers that keep AI engines from reading your site at all (missing
llms.txt, HTML-only content, blocked or unguided crawlers, no agent endpoints) and,
with a 42A account, give you concrete, prioritized recommendations. Sites that are
easy for AI to read, understand and verify are far more likely to be cited.
### Is it compatible with any WordPress theme?
Yes. The plugin works at the request layer: markdown, llms.txt and MCP responses
are served before theme rendering even starts, and nothing in your theme’s HTML
output is modified. It is compatible with classic themes, block themes and page
builders alike.
### What if my site already has an llms.txt?
The plugin checks first and never overrides content your site already provides.
If an llms.txt, llms-full.txt or MCP discovery document already exists – as a real
file on your server or served by another plugin – 42A AI Visibility detects it and
leaves it untouched, generating only the pieces your site is missing. The Agent
Layer checks show which files are generated by the plugin and which existing ones
are being respected. If you remove the existing file later, the plugin starts serving
its own version automatically.
### Does the plugin slow down my site?
No. Markdown documents are generated lazily, cached in transients and invalidated
on save. The markdown/llms.txt/MCP paths short-circuit before theme rendering; normal
HTML rendering is untouched.
### Can other plugins add MCP tools?
Yes – use the `ael42a_mcp_tools` filter. Tools flagged `requires_auth` are rejected
until an authenticated transport ships in a future version.
### Does it work with WooCommerce?
Yes. Product pages get a structured details section (price, currency, SKU, stock,
categories) in their markdown, llms.txt includes product categories, and the MCP
server gains `search_products` / `get_product` tools.
### What about multisite?
v1 supports per-site activation only. Network-wide activation is not officially
supported yet.

## Changelog
#### 1.1.0
* Security: the “Connect to 42A” return flow is now gated by a single-use state
token minted when you start the flow, protecting against cross-site request forgery.
* Lengthened the plugin’s internal name prefixes (`ael42a_` / `AEL42A`) to comply
with WordPress.org naming guidelines. If your site was connected, reconnect it
from the Account tab after updating.
#### 1.0.9
* Corrected the Contributors list to the plugin owner’s WordPress.org username.
No functional changes.
#### 1.0.8
* The plugin now detects content your site already provides before generating its
own. If an llms.txt, llms-full.txt or MCP discovery document already exists (
a real file on the server or one served by another plugin), 42A AI Visibility
respects it and does not override it. Detection runs on activation, daily and
whenever you re-run the Agent Layer checks; the checks report which files are
respected. Developers can force generation per artifact via the `ael42a_respect_existing`
filter.
#### 1.0.7
* Plugin renamed to “42A AI Visibility – Agentic Enablement Layer (AEL)” with a
refreshed description and tags. No functional changes.
* Expanded FAQ covering AI Visibility, GEO, MCP, supported AI search engines and
theme compatibility.
#### 1.0.6
* Plugin slug renamed from `42a-ael` to `ael-42a` (folder, main file, text domain
and internal prefixes) to comply with WordPress.org naming rules – prefixes may
not start with a digit. Functionality is unchanged.
* If you are upgrading from 1.0.5 or earlier: deactivate and delete the old “42A
AEL” plugin, install this version fresh, then reconnect your 42A account from
the Account tab (settings and tokens do not carry over across the slug change).
#### 1.0.5
* New Account tab: all connection management in one place – connect / manual pairing,
organization, brand, who connected the site and when, domain-verification status,
refresh and disconnect.
* The plugin now detects when a site is disconnected from the 42A platform and
clears its local connection automatically (on the next data fetch and via a daily
sync).
#### 1.0.4
* New AI Visibility tab: a read-only snapshot of your 42A brand dashboard – visibility
score, total mentions, sentiment, share of voice, mention coverage, trend charts
and your analysis projects.
* The Agent Layer tab now shows your live AI-visibility metrics in the sidebar
once connected.
* The connect teaser now previews the same dashboard stats.
* The 42A logo is now the wp-admin menu icon, and plugin copy uses plain typography
throughout.
#### 1.0.3
* API error notices now include the HTTP status code, so failures are diagnosable
at a glance.
#### 1.0.2
* Redesigned wp-admin UI in the 42A brand: light design-system theme with the 42A
logo, lime accents and brand colors (all assets bundled locally).
* Fix “Missing Bearer token” errors on hosts that strip the Authorization header
from outgoing requests – the site token is now also sent as an X-42a-Site-Token
header.
* Connected sites are now always tracked under your organization’s main brand (
no brand picker in the connect flow).
* Organization name and domain-verification status now display correctly on the
GEO Vitals tab.
* New GEO insights preview in wp-admin showing what connecting a free 42A account
unlocks.
#### 1.0.1
* MCP discovery now served at every emerging well-known path – `/.well-known/mcp.
json`, `/.well-known/mcp` (SEP-1960 manifest), `/.well-known/mcp/server-card.
json` (SEP-1649 server card) and `/.well-known/mcp-server` (IETF draft) – so
MCP clients implementing any of the draft discovery specs can find the server.
#### 1.0.0
* Initial release: markdown layer (?format=markdown, .md, Accept negotiation),
llms.txt + llms-full.txt, stateless read-only MCP server + /.well-known/mcp.json
discovery, local GEO vitals with robots.txt AI-bot audit, agent-traffic counters,
optional 42A connect flow with domain verification, opt-in telemetry.
