Check, then act, on Base and NEAR: token-safety gates, then swaps at the best price — over x402.

Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
X402_CREDIT_TOKENOptional, secret | Prepaid credit token (ck_…) from the buy-credits service. Sent as the x-credit-token header; each call debits your balance. No wallet or signing needed. Recommended paid mode. Buyable with USDC on Base, or with USDC/USDT/NEAR on NEAR at https://402.com.tr/credits. |
AGENT_PRIVATE_KEYOptional, secret | Hex private key of a Base wallet holding USDC. Used locally to sign x402 payments — never sent anywhere. Use a dedicated low-balance wallet. Optional: without it (and without a credit token) the server runs on the free tier. |
X402_BAZAAR_CATALOGOptional | Override the catalog URL (default https://402.com.tr/api/catalog). |
