WordPress 6.9 gives AI integration an actual standard
A client wanted a sparkle button by Friday. What WordPress 6.9 actually shipped matters more: the Abilities API and the MCP adapter, which give AI agents a defined way to talk to a site.

A wrapper around a few REST endpoints wasn’t enough to keep an AI agent alive through a timeout. Version 0.3.0 of the WordPress MCP Adapter covers what I had to hand-roll: HttpTransport, WP_Error responses, prefixed hooks and one event stream.
A client’s plugin kept bouncing back out of the queue, so here is what changed: 60,187 plugins in the directory, 7,670 submissions this year, and 85.3% of first reviews started by an automated scanner rather than a person.
A synchronous OpenAI call on image upload hung the admin for five seconds. The AI Experiments plugin v0.1.0 points at a different route: registered Abilities, the WP AI Client, and MCP.
Pointing an LLM at an undocumented WooCommerce extension produced hooks that never existed. Extracting the real hook list with PHP first, then prompting, is what separates a usable draft from a liability.
I once spent three weeks bolting a permissions layer onto custom REST endpoints so an AI agent could not wreck a client’s product catalog. The Abilities API landing in WordPress 6.9 is the standard that job was missing.
A client’s AI recommendation engine turned out to be raw curl calls dropped into single.php, pinned to a deprecated API version. Core’s PHP AI Client and Abilities API work is the standard that kind of build has been missing.
A client’s AI plugins each shipped their own settings screen and each asked for API keys they had already entered. The Core AI check-in from October 8th, 2025 covers both fixes: categories on the Abilities API, and one provider settings screen.
An off-the-shelf AI plugin left a client with a slow backend and alt text that had nothing to do with the images. The core AI discussions point somewhere better: content summaries, post titles and image descriptions behind one PHP AI Client.
A client wanted AI features on his WordPress site and every plugin used a different API. The new WordPress AI Client SDK gives plugins and themes one consistent, WP-native API for multiple providers.
