Add Twelfth to Claude (claude.ai) in one click from Claude’s connector directory. The connection reads by default and changes nothing unless you turn on Allow changes when connecting. There is no key to copy.
Sign in with your Twelfth account. Works on web, desktop and mobile.
Add Twelfth to Claude
- Open Twelfth in Claude’s directory and add it. In Twelfth, Settings → AI & agents → Add to Claude opens the same page.
- Claude sends you to Twelfth. Sign in, choose the workspace and the read tools Claude may use, and approve.
- Ask Claude what Twelfth can do. The connection shows on the Usage tab of Settings → AI & agents.
That is all. The connection reads as you, within your remits. Connectors you add on claude.ai are also available in the Claude desktop and mobile apps. End the connection from Settings → AI & agents at any time.

If your organisation blocks directory connectors

Sign in to Twelfth when Claude asks.
