Every agent accepts Tempo USDC, Base USDC, or Solana USDC. You fund a wallet once and the MCP pays per run automatically — you never handle a 402, sign a transaction manually, or refresh a session.Documentation Index

The three rails
| Rail | Network | Wallet key |
|---|---|---|
| Tempo USDC | Tempo mainnet | secp256k1 (shared with Base) |
| Base USDC | Base mainnet | secp256k1 (shared with Tempo) |
| Solana USDC | Solana mainnet | ed25519 |
wallet_setup({ action: "create" }) call gives you an EVM wallet that covers both Tempo and Base. Solana needs a separate wallet (wallet_setup({ action: "create", chain: "solana" })) because the key type is different.
Picking a rail for a run
If you don’t specify, the MCP picks the default chain from your default wallet. To force a specific rail:pay_with accepts tempo, base, solana, or a specific wallet ID.
Refunds
If an agent run fails, the charge is refunded automatically to the wallet you paid from. The MCP surfaces a refund confirmation with the result. You never pay for a failed run. Input validation (missing required fields, wrong types) happens before payment, so a typo doesn’t cost you anything either.Credit packs
Some agents offer prepaid packs that cost less per run than the PAYG price. If an active pack exists for an agent, future runs consume pack units instead of charging your wallet. See Credit Packs for details.Checking your wallet
