BankBridge with ChatGPT Enterprise

2 min read
Add BankBridge to ChatGPT Enterprise once, then ask it about your real bank accounts, transactions, subscriptions, and investment holdings. Every question live-fetches in real time — nothing is cached. $5/mo per connected bank.

Setup

Paste the config below into admin Connector Registry. Swap the placeholder key for your real bbk_ key from your dashboard.

1. chatgpt.com/admin → Connectors → Custom connectors → Add
2. URL: https://bankbridge.money/api/mcp
3. Authentication: Custom token
4. Header: Authorization: Bearer <member's bbk_ key>

(Each member uses their own BankBridge API key — financial data is
 per-user, so there's no shared-credential mode.)

The full doc page for ChatGPT Enterpriseauto-fills your real key when you’re signed in.

Three prompts to try

  • “List my bank accounts and current balances.”
  • “How much did I spend on food this month?”
  • “What are my recurring subscriptions?”

If it doesn’t work

Check the ChatGPT Enterprise doc page for the Troubleshooting section. 90% of first-time failures are either a missing Bearer prefix (note the space) or a placeholder key that didn’t get replaced with a real one.
