AI-assisted plugin development

Scaffold plugins, generate hooks, refactor architecture, write tests — agent in the loop.

1. Overview

WordPress plugin work is 80% repetition. MCP-aware agents get great at the repetition.

2. Development pipeline

  1. 1

    Brief

  2. 2

    Scaffold

  3. 3

    Hook gen

  4. 4

    Refactor

  5. 5

    Test

3. Scaffold a plugin

plugin.php php
<?php
/**
 * Plugin Name: My MCP Plugin
 * Version: 0.1.0
 */
add_action('init', function () {
    register_post_type('mcp_log', ['public'=>false,'show_ui'=>true]);
});

4. Hooks & filters

Expose wp.hooks.search as an MCP resource. The agent finds the right hook by name, signature, and example usage — no more guessing.

5. Tests & refactors

tests/PluginTest.php php
<?php
class PluginTest extends WP_UnitTestCase {
  public function test_cpt_registered() {
    $this->assertTrue(post_type_exists('mcp_log'));
  }
}

Agents that ship plugins

Scaffold → hook gen → refactor → test.

You review. Agent runs.
