Connect your agent

Three steps: add the MCP server, hold a little USDC, call tools. No signup, no API key — the payment is the authentication.

1. Add the MCP server

   Any MCP-compatible client (Claude, GPT, Gemini, custom agents) can connect over streamable HTTP:

   {
     "mcpServers": {
       "atlas": { "url": "https://64.225.40.23.sslip.io/mcp" }
     }
   }

2. Fund an agent wallet with USDC

   Payments settle as USDC via the x402 protocol. Give your agent a wallet using any x402-capable client — e.g. Coinbase AgentKit or the x402 SDK — holding a few dollars of USDC. Typical calls cost $0.001–$0.01.

3. Call tools — payment is automatic

   An unpaid call returns the terms in the standard x402 shape:

   {
     "x402Version": 2,
     "accepts": [
       {
         "scheme": "exact",
         "network": "eip155:8453",
         "asset": "0x8335...2913 (USDC)",
         "amount": "1000",
         "payTo": "0x...",
         "maxTimeoutSeconds": 300
       }
     ],
     "error": "Payment Required"
   }

   x402-aware MCP clients read this, sign the USDC payment, retry, and get the result — round trip under two seconds. Your agent code just… calls the tool.
