Works with AI assistants
Lumtera registers its checks with the WordPress Abilities API, so AI agents can check content, read a post's issues or the site summary — with normal WordPress permissions.
Overview
On WordPress 6.9 and later, Lumtera registers four abilities with the WordPress Abilities API: lumtera/check-content, lumtera/check-post, lumtera/site-summary and lumtera/list-rules. Abilities are WordPress's standard way for a plugin to describe what it can do, with a schema for the input and output, so an AI assistant or automation tool can find and call them without custom code.
check-content takes HTML or block markup and returns a score, counts and every issue with its WCAG criterion, message, how to fix it and the markup involved; nothing is saved. check-post checks a saved post by ID and updates its stored results. site-summary returns the site totals and the ten most common issues. list-rules returns every check with its criterion, level and current severity.
The abilities are published to the Abilities REST endpoints and marked for MCP, so an assistant connected through the WordPress MCP Adapter can use them. A typical use: the assistant drafts a post, runs check-content on the markup, fixes what it can and leaves the judgment calls to a person. Every call runs as the WordPress user the assistant is connected as.
Why it matters
More and more site work happens through AI assistants. If they cannot see accessibility results, they will happily write content with the same problems a person would.
What you get
- Abilities to check content, check a post, get the site summary and list the checks.
- Each ability respects the same capabilities as the Lumtera screens.
- Also available as a REST API (lumtera/v1) for your own tools.
How it works
-
Install Lumtera
On WordPress versions with the Abilities API, the abilities register automatically.
-
Connect your assistant
Any client that discovers WordPress abilities can call them.
Who it helps
-
Teams drafting with AI
An assistant can check its own output before handing it over, so drafts arrive with fewer automated issues for an editor to find.
-
Site managers asking questions in plain language
Ask an assistant how the site is doing and it can call site-summary for real numbers instead of guessing, if your account can see the reports.
-
Developers building automation
Scripts and workflow tools can call the same abilities through the Abilities REST endpoints, with schemas that describe every field.
Good to know
How it behaves, what it needs, and where its limits are.
- Permissions
- check-content and list-rules need the edit_posts capability. check-post needs permission to edit that post. site-summary needs the same capability as the reports, edit_others_posts by default.
- Read-only except one
- check-content, site-summary and list-rules only read. check-post updates the stored results for that post, like Re-check in the Content report. No ability changes post content.
- No AI inside
- The abilities are ordinary server-side functions. Lumtera does not call an AI service to run them, and the results match what a person sees in the sidebar.
- Older WordPress versions
- Before WordPress 6.9 the Abilities API is not available, so the abilities are not registered. Everything else in Lumtera works as usual.
- Your assistant, your review
- Lumtera controls what the abilities return, not what an assistant does with it. Review an assistant's edits as you would any editor's.
Questions
Something else on your mind? Contact support
Does this send my content to an AI service?
No. Abilities are just a documented way to call Lumtera. What an assistant does with the results is up to the assistant you choose.
Which assistants can use this?
Any client that can call WordPress abilities, for example through the WordPress MCP Adapter. Lumtera does not include its own connector.
Can an assistant dismiss issues?
There is no dismiss ability. Dismissals are made by a person in the block editor sidebar or the Elementor panel.
What is the lumtera/v1 REST API for?
It powers Lumtera's own screens: live checks, stored issues, re-checks, dismissals, bulk scans and a site summary. It uses normal WordPress authentication and permission checks. For automation, the abilities are simpler because they describe their own inputs and outputs.
