Or set it up by hand

1. Add the Develop21 connector

On claude.ai (in the browser), go to Settings → Connectors → Add custom connector, and paste:

https://mcp.develop21.ai/api/d21-6de08244/mcp

Connect on the web rather than the desktop app — desktop picks the connection up after a full restart.

2. Approve the connection

Your Develop21 account is created as you connect — sign in with Google or your email, confirm you're over 18, and approve. No forms, no card.

3. Install the Chrome extension

One-click job capture from any listings page: add the Develop21 extension. On mobile, paste the job description text into your chat thread instead.

4. Test it
