This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
EVM_PRIVATE_KEYOptional, secret | 0x private key of a DEDICATED wallet holding USDC on Base. OPTIONAL: product search and the tax calculator are free and work without any wallet; only search_by_image and the link comparison return 402 without it. |
SOLANA_PRIVATE_KEYOptional, secret | base58 or JSON-array secret key of a DEDICATED Solana wallet holding USDC (pays per call). Configure this and/or EVM_PRIVATE_KEY; the x402 layer settles on whichever rail the 402 advertises. |
SOLANA_RPC_URLOptional | Optional Solana RPC override used to build the payment (e.g. a Helius URL). |
BRMARKET_BASE_URLOptional | Base URL of a brmarket Worker. Defaults to the hosted production API (https://brmarket.thomenz.me). |
X402_NETWORKOptional | 'base' (mainnet, default) or 'base-sepolia' (testnet). |
