Connect an AI You Already Use
Your Brain doesn't have to live in this app. Plug it into Claude, ChatGPT, Cursor, or anything else that speaks MCP — and every one of those tools wakes up knowing your business.
For Claude and ChatGPT there's no key to manage: you copy one URL, sign in, and approve. Keys are only for developer tools.
What it does for you
The Simple path — Claude and ChatGPT:
- Open the connect dialog, copy the MCP server URL it shows — it's pinned to this workspace, so the connector only ever sees this workspace
- Add it as a custom connector (Claude: Customize → Connectors; ChatGPT: turn on Developer mode under Settings → Security and login, then add it under Plugins)
- Sign in on the MarketingSecrets page that opens and click Approve & continue
- Connecting a second workspace? Open the dialog from that workspace's Memories page and add a second connector with the URL it shows
The Advanced path — Brain keys for developer tools:
- Claude Code, Custom GPT Actions, Cursor, and curl authenticate with a Brain key instead
- Keys are generated in the dialog's Advanced tab, shown exactly once, auto-named for the tool, and revocable the moment you want them gone — revoked keys stop working immediately
Same facts, same answers:
- Connected tools can search your Brain, read your profile, save new memories, and pull recent ones
- Anything saved from an outside tool shows up in What it knows
- Anything you teach inside MarketingSecrets.ai is instantly available to every connected tool
- It works in one direction: the connected AI reads and writes your Brain, but MarketingSecrets.ai can't read that AI's chat history or memories. To bring them over, ask ChatGPT or Claude to save what it knows about you to your Brain, or upload a ChatGPT data export on the Memories page
Always visible, always reversible:
- Each provider card shows its Connected state, and the page shows when a connected AI last read your Brain
- Disconnect from the same card any time
How you use it
- Open Chief of Staff → Manage → Memories and scroll to Connect an AI you already use.
- Pick your tool — Claude, ChatGPT, Cursor, or API.
- Follow the Simple steps for Claude or ChatGPT (copy URL → add connector → sign in and approve). Use Advanced only for Claude Code, Custom GPTs, Cursor, or your own code.
- Open that tool and ask it something only your Brain would know — "what's our pricing for the high-tier offer?"
Building something yourself? The Connect via MCP client guide has the per-tool setup configs, and the Brain API Reference documents every tool and error code.
If you only do one thing today: connect Claude. Two minutes, no key, and the first answer is the moment your Brain stops being trapped in one app.
