# Nexter Abilities Explained: The WordPress Abilities API Inside Nexter Blocks

## Key Takeaways

- Nexter ships 84 abilities across the Suite in May 2026, with 26 on Nexter Extension and 58 on Nexter Blocks.
- WordPress Core's Abilities API standardizes permissioned actions so an AI agent can create a post, update a setting, or query data instead of screen-scraping the admin.
- Nexter Extension turns on MCP Abilities from Connection → Enable MCP Abilities, letting Claude, ChatGPT, or Cursor read and modify a Nexter-powered WordPress site through the Model Context Protocol.
- Nexter Extension abilities cover templates, code snippets, SMTP, security, performance, image optimization, and custom fonts.

Point Claude, ChatGPT, or Cursor at a WordPress site, and it needs a defined, permissioned way to actually read and change things — not screen-scraping the admin. That's what the WordPress Abilities API standardizes, and in May 2026 Nexter shipped 84 of its own abilities across the Suite: 26 on Nexter Extension, 58 on Nexter Blocks. Here's what that actually means and how to turn it on.

## What the Abilities API Is, Briefly

WordPress Core's Abilities API is the standard that lets an AI agent discover and call specific, permissioned actions on a WordPress site (create a post, update a setting, query data) instead of relying on generic API access or UI automation. WordPress Core's own AI plugin reached version 0.9.0 the same month Nexter shipped its abilities, adding an approval system and tighter API-key security — the two releases landed in the same window deliberately, on the same emerging standard.

## What Nexter Shipped: 84 Abilities Across the Suite

- **26 abilities on Nexter Extension** — covering templates, code snippets, SMTP, security, performance, image optimization, and custom fonts.
- **58 abilities on Nexter Blocks** — laying the groundwork for AI-driven work inside the Gutenberg editor itself.

## How to Turn It On

From the Nexter Extension dashboard, go to **Connection → Enable MCP Abilities**. Once enabled, an AI agent such as Claude, ChatGPT, or Cursor connected to your site through the Model Context Protocol can read and modify your Nexter-powered WordPress site directly, within whatever abilities you've enabled and whatever permissions your setup grants it.

## Why This Shipped Before the Core API Was Fully Stable

Nexter's own release notes framed the timing directly: the goal was to be one of the first plugin Suites with a real, live ability catalogue, rather than waiting for the Core standard to fully settle. That's a real trade-off — an emerging standard can still change — worth knowing if you're deciding how much of your workflow to build around it today versus waiting for a more mature spec.

## FAQ

### Do I need a separate MCP server plugin to use Nexter Abilities?

Nexter Abilities are enabled from within Nexter Extension itself (Connection → Enable MCP Abilities); check current documentation for whether your setup also needs a general-purpose MCP server layer depending on which AI tool you're connecting.

### Which AI tools can use Nexter Abilities?

Nexter's own release notes name Claude, ChatGPT, and Cursor as tools that can connect once abilities are enabled.

### Is enabling abilities risky for a production site?

Enabling AI-agent access to modify a live site is a meaningful permission grant; review which specific abilities you enable and treat it the same way you'd treat any other admin-level integration, testing on staging first if you're unsure.

## Conclusion

84 abilities is a lot of surface area to enable at once — start with a narrow set of read-only or low-risk abilities, confirm the connection works as expected, then expand from there rather than turning everything on in one step. The Abilities API is still an emerging standard, and a cautious rollout costs you nothing.
