Your agent, ready in one paste

Get a free XRPL wallet seed, then paste this into Claude Desktop or any MCP-compatible client.

claude_desktop_config.json
{
  "mcpServers": {
    "polymitapay": {
      "command": "npx",
      "args": ["-y", "@polymitapay/mcp"],
      "env": {
        "POLYPAY_WALLET_SEED": "s...",  // your XRPL wallet seed
        "POLYPAY_NETWORK": "testnet"  // or "mainnet"
      }
    }
  }
}
Never commit your seed. Cursor, Windsurf, and VS Code can pull it from an environment variable instead of storing it in the file. Claude Desktop only accepts the plain value, so treat that config as a secret.

Restart your client and the tools show up.

Set up in three steps

If your server already speaks MCP, you're most of the way there.

1

Connect

Point PolymitaPay at your MCP server's URL — no code changes required.

2

Price

Set a price per tool, in XRP or RLUSD.

3

Get paid

Every call settles on XRPL automatically, straight to your wallet.

Your agent

Searches the catalog and signs a payment with its own wallet

PolymitaPay

Meters the call, settles the x402 payment on XRPL

Your MCP server

Runs the tool call and gets paid, per call, automatically

See it in action

A real search-then-pay exchange between an agent and the catalog — no code on either side.
