Description
Sometimes, when you are developing something new or trying to find a problem, you need to read raw information. In that case, this plugin is the right tool - but it is too powerful, so it is not for everyone.
KC Tools is a power-user plugin for developers and site administrators who can write code. It intentionally exposes low-level information and actions from inside /wp-admin/ so you can debug, diagnose, or repair a WordPress installation when the normal UI isn't enough.
This plugin does nothing else - no output on pages, no widgets - it only adds a new row under Settings in the WordPress admin area.
Who is this for?
Bloggers, self-webmasters, average users: this is not the right tool for you. It can (and will) destroy your site within seconds. No joke…
Developers: generally, not for you either. But if you are brave enough and want to learn - you are welcome.
Imagine your plugin is a car (80 kW, 110 hp). WordPress itself is a truck (450 kW, 600 hp). KC Tools is not a truck. It's not a locomotive (1,500 kW) either. Also not a haul truck (2,610 kW, 3,500 hp). It's a ship (81 MW)… but it's not a rocket. Be warned.
What’s inside
Environment
- Server environment overview
- PHP configuration (phpinfo-style output)
WordPress
- Menu location & navigation hints (so you know where everything lives in wp-admin)
- View/edit
wp-config.phpfrom the admin panel - Create a backup of
wp-config.phpbefore changes
Database / DB
- Browse tables, inspect rows, and run SQL queries
- SQL input is a large text area (supports long queries and multiple statements in sequence)
- Re-run the last SQL query
- Deep inspection of JSON-encoded and/or serialized values - including when they are nested inside other encoded arrays/objects
SSH-like console
- Terminal-like tool to execute server commands (HTTPD user rights)
- Good for quick checks; no continuous tasks like

Hidden debug helpers
KC Tools may include developer helpers such as debug output to email/file/URL, and optional endpoints/shortcodes intended for controlled debugging. Treat them as sensitive (see Security). Requires PHP 7+.

Security notice (read this twice)
KC Tools is a developer scalpel. Used incorrectly, it can leak secrets or damage your database in seconds.
- Change the password in the plugin file (search for
$thepassword) before you enable it anywhere. - Review and change any default debug email addresses used by debug helpers (if present).
- Keep access restricted to trusted admins only.
- Prefer staging environments.
- Assume DB + command tools can do irreversible damage. They can.
If you need a formal disclaimer, see: KC Tools License
Installation
- Upload the plugin folder to
/wp-content/plugins/(or upload the ZIP from Plugins → Add New). - Immediately change the password value (
$thepassword) and any default debug emails. - Activate KC Tools.
