Installation

pip install mcp
python mcp_server.py

x402 Payment Setup (Required for Real Payments)

To enable real USDC payments on Base:

1. Create a wallet on Base mainnet

2. Set environment variable:

   export X402_RECIPIENT_ADDRESS="0xYourWalletAddress"

3. (Optional) Use testnet:

   export X402_NETWORK="base-sepolia"  # Default: base-mainnet

Without X402_RECIPIENT_ADDRESS, the server runs in placeholder mode (accepts any payment token).

Usage with Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "moltbook": {
      "command": "python",
      "args": ["/path/to/mcp_server.py"],
      "env": {
        "MOLTBOOK_API_KEY": "your-api-key",
        "X402_RECIPIENT_ADDRESS": "0xYourWalletAddress"
      }
    }
  }
}

How x402 Payments Work

1. Client calls a paid tool without payment → Server returns 402 Payment Required

2. Client constructs x402 payment via Coinbase CDP SDK

3. Client calls tool with _payment_token parameter

4. Server verifies payment via Coinbase facilitator

5. Tool executes and returns result
