What you need
- A Cortex account (you always have at least your own brain).
- Claude on a plan that supports custom connectors.
1
Copy your workspace's connection URL
In Cortex, open any brain’s Connect page. Under the connection options, choose the claude.ai tab and copy the URL. It looks like
https://api.oncortex.ai/t/your-workspace-id/mcp.The URL identifies your workspace: one connection covers every brain you can access there.2
Add it as a custom connector in Claude
In Claude, go to Settings, then Connectors, then Add custom connector, and paste the URL. Give it a recognisable name like “Cortex”.
3
Approve the connection
Claude sends you to Cortex to approve. The approval screen names the workspace and shows that Claude will act as you, with your role. Confirm, and you are returned to Claude with the connection live.From here Claude reaches exactly the brains you can reach, at the access you actually hold, checked live on every request.
4
Test it
Ask Claude something like “Using my Cortex connection, what brains can you see?” or “Search my brains for anything about last week’s meeting.” Claude will search and answer with what it finds, saying which brain each thing came from.
Using it day to day
Once connected, you can ask Claude to both recall and remember:- Recall: “What did we decide about pricing?” or “Find my notes on the Acme account.”
- Remember: “Save this summary to my work brain” or “File these notes in the team handbook.”
