Sign in to MixShift

Once the plugin is installed, you sign in once and the plugin keeps your session fresh from then on. The whole flow takes about 30 seconds.

Sign in from a chat

1. Open any chat and say "sign in to mixshift" (or just "welcome" if you are brand new).
2. Claude asks for your work email, then opens the MixShift sign-in page in a browser tab.
3. Sign in with your MixShift email and password. Your credentials stay on the sign-in page; the plugin never sees them.
4. Return to the chat and say "done".

Claude confirms the sign-in and shows the brands you have access to.

Try it

• "What brands do I have access to?"
• "Show me last week's ad spend for [your brand]."
• "Explore my data."

If Claude returns your brands and data, you are set.

Good to know

• Sign-in uses short-lived tokens that refresh automatically. There are no database passwords to manage and no IP allowlists to set up.
• To switch accounts, just sign in again with the other email.
• Everyone at your MixShift org sees the same brands once signed in. Per-user data scoping is not available today.
• In a terminal, mixshift auth login does the same thing for CLI users.
• To check whether you are signed in, run mixshift auth status. It shows who you are signed in as, whether it is a person or a service credential, and when the session expires. It only reads what is saved on your computer: it never signs you in or contacts the sign-in service. When you are signed out it tells you how to sign in from a chat.

Signing in from other tools

claude.ai connectors, ChatGPT, Cursor, and Codex reach MixShift through the MCP server rather than the plugin. See Connect AI tools over MCP.

Unattended and scheduled work

Anything that runs with nobody at the keyboard (scheduled tasks, automations, CI) uses a service credential instead of a personal sign-in. See Run unattended and scheduled tasks.
