One System CRM

One System for Claude

Last updated: November 5, 2026

Change your website by asking Claude or ChatGPT. “Change our Saturday hours to 9–2.” “Write a blog post about winter boiler checks and save it as a draft.” “Add alt text to the images on the home page.” Claude does it, and One System keeps a record of every change with the original, so you can undo it any time.

Free. Works on Claude’s free plan too. No API key, no extra AI cost. Find One System in Claude’s connector directory ↗

Set it up in three steps

  1. Install the One System CRM plugin on your WordPress site (Plugins → Add New, or download it from your One System account) and click Connect to One System. New here? Create a free account on the way — it takes a minute.
  2. Add the connector in Claude: open One System in Claude’s connector directory and click Connect (or Settings → Connectors → Add custom connector with https://copilot.onesystemcrm.com/mcp). In ChatGPT: Settings → Security and login → Developer mode, then add an app with the same address and OAuth.
  3. Sign in to One System and choose Allow. If you have more than one business, pick the one whose website Claude should work on.

Then just ask, for example: “Use One System to show me my latest blog posts.”

What Claude can do

  • Pages built with Elementor: texts, buttons, images, links, list items, the visible text of HTML blocks, colors and fonts, a phrase everywhere on the site.
  • Every post, page and product (block editor and classic editor too): titles, excerpts, content, featured images, publish or keep as a draft, categories and tags.
  • New posts and pages — always saved as drafts first; Claude publishes them only when you ask.
  • SEO: Google titles and descriptions, image alt text, titles and captions, page addresses (the old address forwards), menus.
  • llms.txt — a plain-text summary of your business for AI assistants, served at /llms.txt.
  • Websites built with code (React, Next.js, Vite) connected with the developer kit: the texts, links and images your developer made editable.
  • Social posts for Facebook, Instagram and more (they wait for your OK in One System).

How it stays safe

  • You confirm in Claude. Claude asks before it changes your website. You can also ask for a preview instead: Claude prepares it and you approve it in One System.
  • Every change is recorded in One System → Changes: what it was before, what it is now, who asked and from which app. Undo restores the original — from Claude (“undo that”) or from One System.
  • Only allowed changes. The plugin accepts a fixed list of edits. It never runs code, never edits theme or plugin files, never installs plugins, never changes users or security settings, and never adds shortcodes or scripts.
  • Your team’s permissions apply. Only admins, and team members allowed to publish website changes, can change the website from Claude.
  • Your website’s content is data. Claude reads it to make the change you asked for; it isn’t used to train models. See our Privacy Policy.

Questions

Does it cost anything? No. The connector is free. One System’s paid services (website changes inside One System, SEO, CRM, Shield) are optional.

Which websites work? WordPress (6.5 or newer, plugin 1.7 or newer for posts, products and llms.txt) and websites built with code using our developer kit.

Can I disconnect it? Yes: in One System → Settings → AI, or remove the connector in Claude. Your website keeps every change; the records stay in One System.

Something went wrong? Ask Claude to undo it, or use Undo in One System → Changes. Need help? Email support@onesystemcrm.com.
