What the publisher says

From the Navi X402 repository's README, as published. We do not edit it. Read it on GitHub

navi-x402-mcp

MCP server that gives your AI agent paid superpowers with zero API keys: live crypto prices, weather + air quality, translation, AI market reports, web page intelligence, Google Sheets reading, URL previews — and navix402scout, which finds the best x402 service in the ecosystem for any task.

Every call is paid per-request in USDC on Base via the x402 protocol (prices: $0.001–$0.02). No accounts, no API keys, no subscriptions: your agent's wallet pays only for what it uses.

Setup

  1. Fund a wallet with a few USDC on Base mainnet (a dollar goes a long way).
  2. Add to your MCP client config (Claude Desktop, Cursor, etc.):
{
  "mcpServers": {
    "navi-x402": {
      "command": "npx",
      "args": ["-y", "navi-x402-mcp"],
      "env": {
        "X402_PRIVATE_KEY": "0x<private key of the paying wallet>",
        "MAX_PRICE_USDC": "0.05"
      }
    }
  }
}

Tools

Tools are generated dynamically from the live Navi catalog — new endpoints appear automatically. Current highlights:

  • MAXPRICEUSDC (default 0.05) hard-caps the per-call price the server

authorizations locally; settlement happens on-chain via the Coinbase facilitator.

  • The private key never leaves your machine: it signs EIP-3009 transfer

payments instead of failing silently.

  • Without X402PRIVATEKEY, tools are listed and explain how to enable
