Cursor

Connect Cursor to the active workspace by adding Twelfth as an
MCP server. The connection is read-only.
Reach it from Settings → AI & agents → Cursor.

Connect

  1. In Twelfth, open Settings → AI & agents and choose Connect an agent → Cursor. Twelfth creates a key for this connection, copies it to your clipboard, and starts waiting for Cursor’s first request. Copy the key now if you need it again — Twelfth shows it only once.
  2. In Cursor’s MCP configuration, add a server pointing at the Twelfth endpoint shown on the connection’s row, with the key Twelfth just copied for you.
  3. Reload Cursor’s MCP servers, then ask it to list Twelfth’s tools to confirm the connection.

Follow the exact steps on the connection’s row in Twelfth — it carries the current
endpoint and the ready-to-paste MCP server entry for your workspace.
