Only the agents you let in.
A gate in front of your MCP, API or any service. Agents get in with a key you list.
01 · How it admits
You list keys. They sign.
Each call is signed with an admitted key. Nothing is paid, and the key needs no funds.
The check runs in your server.
02 · Grants
An admitted key signs a grant for another key.
One tool or all, until a set time. The grant works only for the key it names.
Drop a key from your list and its grants stop.
03 · What it costs
10,000 checks a month free.
Then 2,000 checks for $1 USDC, from a credit wallet you fund with USDC on Base. No ETH.
When credit runs out: refuse, or allow and warn.
The plugin makes the credit wallet and shows its address. Keep at least $1 in it.
04 · Gate and paywall
Gate, paywall or both.
Both admits only your keys and charges them your price. You keep 90.01% of each sale.
Paid calls are not gate checks.
