+# Codex Blog Abilities
+
+Codex Blog Abilities is a small WordPress plugin that exposes guarded blog
+administration actions through the WordPress MCP Adapter.
+
+It is intended for a trusted MCP client, such as Codex, that authenticates with a
+WordPress Application Password.
+
+## Requirements
+
+- WordPress 6.9 or newer
+- PHP 7.4 or newer
+- The WordPress MCP Adapter plugin
+- A WordPress user with the capabilities required for the requested action
+
+## Abilities
+
+The plugin registers public MCP abilities under the `codex-blog/` namespace:
+
+- `get-site-info`
+- `list-post-types`
+- `list-posts`
+- `get-post`
+- `create-post`
+- `update-post`
+- `delete-post`
+- `list-terms`
+- `create-term`
+- `update-term`
+- `delete-term`
+- `list-comments`
+- `update-comment`
+- `delete-comment`
+- `list-media`
+- `list-plugins`
+- `activate-plugin`
+- `deactivate-plugin`
+- `get-options`
+- `update-options`
+
+## Safety Model
+
+The plugin relies on native WordPress capabilities before executing actions.
+For example, post edits require `edit_post`, plugin management requires
+`activate_plugins`, and option changes require `manage_options`.
+
+The option update ability is intentionally restricted to a small allowlist of
+common site settings. It does not expose arbitrary `update_option()` access.
+
+Deactivation of `mcp-adapter` and this plugin is blocked by default so an MCP
+client does not accidentally remove its own control plane.
+
