Package (npm 0.1.12)

npx -y @forgemeshlabs/[email protected]

Or add to your MCP client config:

{
  "mcpServers": {
    "x402-notary-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@forgemeshlabs/[email protected]"
      ],
      "env": {
        "WALLET_PRIVATE_KEY": "<YOUR_VALUE>"
      }
    }
  }
}

WALLET_PRIVATE_KEY secret — Dedicated low-balance Base wallet private key for x402 USDC micropayments. Optional — verification tools work without it. Never use your primary wallet.
NOTARY_RAIL — Payment rail: base or solana. Defaults to base, or solana when NOTARY_BASE_URL contains notary-solana.
