rwagenthub-mcp

MCP server for AgentHub — gives any MCP-compatible AI client access to 19 APIs (flights, hotels, weather, crypto, DeFi, web search, code execution, and more) paid automatically via x402 USDC micropayments on Base.

Requirements

• Node.js >= 22
• A Base wallet with a small USDC balance (most APIs cost $0.01–$0.06 per call)

Setup

1. Get a wallet private key

Create a dedicated wallet on Base Mainnet and fund it with a few USDC. You can use Coinbase Wallet or any EVM wallet.

Use a dedicated wallet with a small balance — not your main wallet.

2. Add to your MCP client config

Claude Desktop — edit claude_desktop_config.json:

{
  "mcpServers": {
    "agenthub": {
      "command": "npx",
      "args": ["-y", "rwagenthub-mcp"],
      "env": {
        "MCP_WALLET_PRIVATE_KEY": "0x..."
      }
    }
  }
}

Cursor / Cline / Windsurf — same config format, check your client's MCP settings.

3. Restart your client

The server fetches the latest API list from the gateway on startup — no manual updates needed.

How it works

Your MCP client (Claude Desktop, Cursor, etc.)
        │  stdio
        ▼
  rwagenthub-mcp  (this package)
        │  POST /v1/call + x402 auto-payment
        ▼
  AgentHub Gateway (Railway)
        │
        ▼
  Flights · Hotels · Weather · Crypto · DeFi · Search · ...

On startup, the server fetches the live API schema from the gateway — so new APIs and price changes are reflected automatically without updating the package.
