### Request tokens via the faucet UI

1. Open [faucet.chainstack.com](https://faucet.chainstack.com/) and sign in to your Chainstack account.
2. Select a testnet.
3. Paste the destination address and submit.

The faucet tops up your address to a per-network cap. Each address can request once every 24 hours.

### Request tokens via the MCP server

The [Chainstack MCP server](/docs/chainstack-mcp-server) exposes a `request_testnet_funds` tool so AI agents can fund a testnet address directly from your coding environment. Authentication uses your Chainstack API key.
