Connect Modula to Claude.ai

Claude.ai supports remote MCP servers on all plans — Free, Pro, Max, Team, and Enterprise. Once Modula is connected, Claude can build interactive content block by block in any conversation.

What you’ll need

  • A Claude account (claude.ai) — any plan
  • A Modula account — sign up here

Limits ⚠️

Claude.ai’s built-in artifact preview runs in a sandboxed iframe that blocks external scripts, so the page cannot load the Modula script as a separate file there. When Claude can run code with network access, it downloads the script and inlines it in the page, and the preview works.

Otherwise: download the script from the link Claude gives you, save it next to the page and open the page locally.

The limitation is specific to Claude.ai’s preview sandbox. The page and its script work without restrictions in your own site, CMS, or LMS.

Steps

1. Open Customize

Go to claude.ai and sign in. Click Customize in the left sidebar (or click your profile icon and select Customize).

2. Go to Connectors

In the Customize panel, select the Connectors tab.

3. Add Modula

Click the + button, then choose Add custom connector. Enter the following address:

https://modula.dev/mcp

Click Add to confirm.

4. Sign in to Modula

Claude will open a Modula login page. Sign in with your Modula account and grant permission. The connection is established automatically once you confirm.

5. Enable Modula in a conversation

Open a new chat and click the + button near the message composer. Select Connectors, then enable Modula for that conversation.

6. Ask Claude to build with Modula

Create a lesson on ancient Rome with a timeline, a short quiz, and a glossary of key terms.

Tips

  • You only need to add Modula once — it stays in your Connectors list for all future conversations.
  • You can enable or disable the connector per conversation using the + menu.
  • To remove the connection, go back to Customize → Connectors and delete the Modula entry.
  • If you use Claude Code or Cursor, see the dedicated integration guides for those tools.
  • Connectors added here are also available in Claude Design.
