Support multiple Stripe accounts in MCP server

[jgalea]

Feature Request

The MCP server currently supports authenticating with a single Stripe account via OAuth. Many businesses operate multiple Stripe accounts (e.g. one per product line or entity) and need their AI agents to access all of them within the same session.
Currently this requires re-authenticating each time, which isn't practical for automated workflows.

Proposed Solution

Support multiple authenticated accounts, either by:

• Allowing multiple OAuth connections with account aliases
• Adding an account parameter to each tool call to specify which connected account to use
• Supporting API key-based auth alongside OAuth for additional accounts

@jgalea we are working on this! Mind sending an email to mcp@stripe.com with your account ID and we can reach out to you to be an early tester

Hey @matv-stripe, friendly nudge on this. I emailed mcp@stripe.com shortly after your reply with my account ID but haven't heard back. Still keen to be an early tester whenever multi-account support lands — let me know if there's anything else you need from me.

Another nudge, @matv-stripe — it's been a couple of weeks since the last ping with no reply on the early-tester invite (account ID was sent to mcp@stripe.com on the same day as my first comment).

Concrete use case in case it helps prioritise: I'm building an AI-assisted year-end bookkeeping pipeline that pulls Transactions / Balance change data from each of our three Stripe accounts (RSS Aggregator, WP Mayor, GLC) and consolidates them into accounting workbooks. With single-account auth I have to either re-OAuth between every account (high friction in an automated agent loop) or fall back to manually downloading three CSVs from the dashboard. Multi-account would unblock end-to-end automation.

Happy to test whatever shape it takes — read-only access across linked Connect accounts, account_id parameter on each tool call, or a switch_account method. Whichever lands first.

@jgalea Hi Jean thank you for the nudge! I'm catching up on some todo's after vacation and we have an experimental preview we'd love to get your thoughts on. I will send more details to you via email!
