# Stripe: an `rk_live_` key is a LIVE key — "restricted" limits what it can do, not which mode it is in

> Stripe's live-mode keys start with pk_live_, rk_live_ and sk_live_. A restricted key (rk_) with write permissions moves real money and touches real customers, exactly like a secret key with the same permissions.

## The trap
"Restricted" sounds safe, and "rk" doesn't look like "sk". But:
- `rk_live_…` is **live mode**: real charges, real refunds, real customer data;
- `rk_test_…` is test mode.

## Practice
- Give tools (dashboards, AI agents, MCP servers) a restricted key with the **minimum** permissions, ideally read-only.
- Treat any `*_live_*` key as production: keep it out of logs, tickets and chat, and rotate it if it leaks.
- To check which mode a key is in, read the prefix, not the name someone gave it.
