true402/mcp-server

Package (npm 1.3.2)

npx -y @true402.dev/[email protected]

Or add to your MCP client config:

{
  "mcpServers": {
    "mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@true402.dev/[email protected]"
      ],
      "env": {
        "WALLET_PRIVATE_KEY": "<YOUR_VALUE>"
      }
    }
  }
}

• WALLET_PRIVATE_KEY secret — Funded Base wallet private key for x402 payment signing (optional; without it, paid tools return the 402 requirements).
• SERVER_URL — true402 API base (default https://true402.dev/api). Must be https (or localhost) — the signer refuses to send a payment over cleartext.
• MAX_PAYMENT_USDC — Client-side per-call spend ceiling in USDC (default 0.10). The signer refuses to auto-pay a 402 whose amount exceeds this — protects the wallet from a hostile endpoint.
