Editing my site live with Claude's MCP, without opening a file

My site is pure HTML and CSS: no CMS, no admin interface. For a long time, every fix was slow and tedious. MCP changed that one point, without changing my method.

The flip side of a hand-coded site is the absence of a backend. Every fix means opening an editor, finding the right file, editing, uploading. For a typo, that is disproportionate.

The problem with a site without an admin

It is not a skill problem, it is a friction problem. A ten-second fix became a ten-minute task, so you postponed it. And postponed small fixes eventually add up to visible debt.

What it looks like now

Today, a fix looks like this, in plain language:

This cursor shows undefined on the home page, it should show Open. Go to my site in Chrome, analyse the source, trace back to the JavaScript block responsible and fix the file directly on the server.

Done. No editor opened, no FTP client, no manual search through files.

I see in real time what it does, every action is described. It is not a black box tinkering: it is a collaborator showing their work.

What it actually changes

• Time saved on low-stakes fixes, the ones you kept postponing.
• Better command of the code, paradoxically: since each action is described, you learn by watching.
• More technical ambition: when friction drops, you attempt things you would not have attempted.

The key point: it replaces neither the design nor the decisions. It removes execution friction on a site I already master. Let loose on code you do not understand, the same tool would produce invisible technical debt. The difference, again, is the frame.

Frequently asked questions

Do you need to know how to code for this?

Yes, to validate. The tool executes fast, but you judge whether the fix is right. On code you do not understand, you accumulate invisible debt.

Is it risky to let it modify the server?

It requires a frame: backups, checking the actions described in real time, and a limited scope. Seeing every action announced changes everything.

Does it replace a CMS?

No. A CMS lets a non-technical client publish alone. MCP removes friction for someone who already masters their code.
