Rekey.dev
Auth for your MCP server, billing for what your agent spends
Auth and billing for agent products, behind one API you host. The OAuth 2.1 server MCP clients expect, plus the credits and quotas your agent bills against. Stripe, PayPal or Razorpay behind one interface. MIT licensed, and the Postgres is yours.
Hey PH 👋
Rekey is the two things you have to build around an agent that aren't the agent: an OAuth 2.1 server an MCP client will actually accept, and credits/quotas that stop the spend instead of reporting it later.
Both live in one tenant model, so login state and subscription state can't drift. Credits debit atomically and return 402 past zero — never a negative balance. Bring your own Stripe, PayPal or Razorpay. docker compose --profile full up and the whole stack is running in your infra, with your Postgres.
MIT licensed, free to self-host forever, no per-MAU meter. $99/workspace/month if you'd rather we ran it.
Happy to answer anything — especially from people who've had a metering bug eat their margin.
