<p>WordPress 7.0 introduced the Abilities API. Any active plugin can register an ability and the WordPress AI feature can then invoke it, consuming whatever credits or tokens your AI provider charges per call. By default every registered ability is exposed, and there is no built-in way to see what is exposed or to limit it.</p>
<p>Codevera AI Access Control adds a single settings screen that lists every plugin which has registered AI abilities, grouped by source plugin, and lets you allow or block each plugin as a whole or each individual ability.</p>
<p><strong>How it works:</strong></p>
<ol>
<li>The plugin watches every call to <code>wp_register_ability()</code> and records which plugin made the call.</li>
<li>The Settings -> Codevera AI Access screen groups those abilities by source plugin so you can see at a glance what is exposed.</li>
<li>Untick a plugin or a single ability and save. From the next request onwards, the AI feature can no longer see or invoke it.</li>
</ol>
<p><strong>Free:</strong></p>
<ul>
<li>Per-plugin and per-ability granular controls</li>
<li>Automatic detection of newly installed plugins that register AI abilities, with an in-admin notification so you can review them</li>
<li>Tamper-detect signature on the saved settings, with a fail-closed mode that blocks every non-core ability if the settings option is modified outside the plugin</li>
<li>Filter-level enforcement that neutralises a blocked ability before WordPress constructs it, plus a registry sweep that removes blocked abilities from the listings</li>
<li>Self-check that re-attaches the enforcement hooks on init, admin_init and rest_api_init if another plugin removes them</li>
<li>Search and filter inside each plugin card so large registries stay readable</li>
<li>No external requests, no telemetry, no licence checks</li>
<li>Works on multisite (per-site settings)</li>
<li>Translation ready</li>
</ul>
<p><strong>Works well for:</strong></p>
<ul>
<li>Sites where editorial staff use the WordPress AI feature and you want strict control over what context the AI can pull in</li>
<li>Agency sites where new plugins are installed regularly and you want to review their AI exposure before letting them in</li>
<li>Privacy-sensitive sites that need an explicit allow list of which plugins may expose data to an AI provider</li>
<li>Compliance-driven environments that need an auditable record of which plugins have been allowed to register AI abilities</li>
</ul>
<p><strong>Under the hood:</strong></p>
<ul>
<li>Uses only the official Abilities API surface: <code>wp_register_ability_args</code>, <code>wp_abilities_api_init</code>, <code>wp_unregister_ability</code></li>
<li>Source attribution from <code>debug_backtrace()</code> of the file that called <code>wp_register_ability</code>, normalised to a plugin slug</li>
<li>HMAC-SHA256 signature on the settings option, keyed to a <code>CVAIAC_SECRET</code> constant or <code>AUTH_SALT</code> fallback</li>
<li>No frontend assets shipped, all code runs in admin and on the AI Abilities REST routes</li>
<li>No database tables, just two options in <code>wp_options</code></li>
</ul>
<h3>External Services & Privacy</h3>
<p>This plugin does not contact any external service. It reads only local WordPress data. No telemetry, no analytics, no licence checks, no remote update checks beyond what WordPress core itself performs.</p>
<p>The plugin stores two options in the <code>wp_options</code> table:</p>
<ul>
<li><code>cvaiac_settings</code> – your allow and block selections, signed with an HMAC-SHA256 signature</li>
<li><code>cvaiac_ability_sources</code> – a map of ability name to source plugin slug, populated automatically as plugins register their abilities</li>
<li><code>cvaiac_schema_version</code> – an integer that records the storage format version, used for migration</li>
</ul>
<p>No personal data, no visitor data, and no AJAX requests to remote services.</p>
<p>When the plugin is uninstalled, all three options are removed.</p>
<h3>Support</h3>
<p>Email info@codevera.ai for support, bug reports, or feature requests. Include your WordPress version, PHP version, a list of other plugins that register AI abilities, and a description of the issue with steps to reproduce.</p>
<h3>Technical Requirements</h3>
<p>Minimum:</p>
<ul>
<li>WordPress 7.0 (required for the Abilities API)</li>
<li>PHP 7.4</li>
</ul>
<p>Recommended:</p>
<ul>
<li>WordPress 7.0 or higher</li>
<li>PHP 8.0 or higher</li>
</ul>
<h3>Privacy & Security</h3>
<p>The plugin does not collect or transmit any personal data. The settings option is stored locally and signed with an HMAC keyed to a site-specific secret. The source-tracker option contains only plugin slugs and ability names that are already public to any code running on the site.</p>
<p>Form submissions use a nonce and require the <code>manage_options</code> capability. The enforcement hooks run on every request that loads the Abilities API, so blocking takes effect from the next request after a setting is saved.</p>
<p>This plugin defends against opportunistic interference such as another plugin writing directly to the settings option, removing the enforcement hooks, or re-registering an ability that has already been blocked. It does not claim to be a security boundary against a fully hostile plugin that has code execution in the same PHP process. The safest practice is still to only install plugins you trust.</p>

Respira for WordPress

<p>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.</p>
<p>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.</p>
<p>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.</p>
<h4>What the Inhale: MCP Abilities plugin does</h4>
<ul>
<li>Lists every registered WordPress ability across all active plugins and themes</li>
<li>Lets you select which abilities are exposed to the default MCP server with simple checkboxes</li>
<li>Shows annotation metadata (read-only, destructive, idempotent) on each ability so you can make informed decisions</li>
<li>Requires explicit confirmation when you inhale an ability marked as destructive</li>
<li>Provides connection info for popular MCP clients (Claude Desktop, Cursor, Claude Code)</li>
<li>Respects each ability’s own permission_callback. The Inhale: MCP Abilities plugin controls visibility, not authorization.</li>
</ul>
<h4>What the Inhale: MCP Abilities plugin doesn’t do</h4>
<ul>
<li>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.</li>
<li>Inhale: MCP Abilities does not register any abilities of its own. It only toggles visibility of abilities other plugins have registered.</li>
<li>Inhale: MCP Abilities does not phone home, collect telemetry, or make external network requests.</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>WordPress 6.8 or later (Abilities API in core since 6.9; 6.8 requires the Abilities API plugin)</li>
<li>PHP 7.4 or later</li>
<li>The official WordPress MCP Adapter plugin installed and active</li>
</ul>
