Inhale: MCP Abilities by Respira

Inhale: MCP Abilities is a small, focused utility that solves one problem: the default WordPress MCP server (provided by the official MCP Adapter plugin) does not expose any registered abilities by default. Site administrators have to write PHP filters to opt each ability into the public MCP surface.

This is the workaround pattern documented in WordPress contributor blog posts and developer guides since the MCP Adapter shipped. Inhale: MCP Abilities replaces the PHP-filter workaround with a simple settings page.

Once installed and activated, you’ll find a new page at Settings > Inhale: MCP Abilities where you can check off the abilities you want exposed to your default MCP server.

What the Inhale: MCP Abilities plugin does

• Lists every registered WordPress ability across all active plugins and themes
• Lets you select which abilities are exposed to the default MCP server with simple checkboxes
• Shows annotation metadata (read-only, destructive, idempotent) on each ability so you can make informed decisions
• Requires explicit confirmation when you inhale an ability marked as destructive
• Provides connection info for popular MCP clients (Claude Desktop, Cursor, Claude Code)
• Respects each ability’s own permission_callback. The Inhale: MCP Abilities plugin controls visibility, not authorization.
• Offers Respira for WordPress as the easiest connection path in the Connection section, and points WooCommerce stores at Respira ARC (free). Both are plain links: nothing loads from respira.press and nothing is sent unless you click.

What the Inhale: MCP Abilities plugin doesn’t do

• Inhale: MCP Abilities does not run any MCP servers, transports, or authentication. Those are handled by the official MCP Adapter plugin, which the Inhale: MCP Abilities plugin extends.
• Inhale: MCP Abilities does not register any abilities of its own. It only toggles visibility of abilities other plugins have registered.
• Inhale: MCP Abilities does not phone home, collect telemetry, or make external network requests.

Requirements

• WordPress 6.8 or later (Abilities API in core since 6.9; 6.8 requires the Abilities API plugin)
• PHP 7.4 or later
• The official WordPress MCP Adapter plugin installed and active

Browse the abilities directory

Respira maintains a public, regularly-refreshed directory of WordPress plugins that register abilities through the Abilities API, including Respira’s own and the Respira WooCommerce add-on. Browse it at respira.press/abilities to see what each plugin exposes to AI agents before you decide which abilities to inhale.
