mcp-server-agentpay

MCP server for AgentPay — the payment gateway for autonomous AI agents.

Fund a wallet once, give your agent the key, and it discovers, provisions, and pays for tool APIs on its own.

Quick Setup

# Add to Claude Code
claude mcp add agentpay -- npx mcp-server-agentpay

# Set your gateway key
export AGENTPAY_GATEWAY_KEY="apg_your_key_here"

Or add to ~/.claude/settings.json:

{
  "mcpServers": {
    "agentpay": {
      "command": "npx",
      "args": ["-y", "mcp-server-agentpay"],
      "env": {
        "AGENTPAY_GATEWAY_KEY": "apg_your_key_here",
        "AGENTPAY_URL": "https://agentpay.metaltorque.dev"
      }
    }
  }
}

Funding Methods

Stripe (human-in-the-loop)

Use fund_wallet_stripe — returns a checkout URL for a human to complete.

x402 USDC (fully autonomous)

Use fund_wallet_x402 — returns endpoint, network, and instructions for autonomous USDC payments via the x402 protocol on Base mainnet. No human needed.

Credit Packages

| Package | Price | Credits | |---------|-------|---------| | micro | $10 | 10 | | small | $45 | 50 | | medium | $80 | 100 | | large | $350 | 500 | | whale | $600 | 1,000 |

How It Works

1. Register — create a wallet, get a gateway key
2. Fund — add credits via Stripe or x402 USDC
3. Discover — agent searches for tools by capability
4. Call — agent calls any tool, gateway handles auth + billing

The agent never needs to know about individual tool APIs, accounts, or payment. One key, every tool.
