MoluAbi MCP Server

# MCP Server Quickstart > Monetize your MCP tools in minutes with ATXP Turn your MCP tools into a revenue stream with pay‑per‑call pricing—without building billing, authentication, or account management. ATXP lets you require payment before execution, so you get predictable income with minimal overhead. * **Earn per-use**: Charge per tool call with flexible pricing. * **Programmatic enforcement**: Require payment before execution with a single middleware and helper. * **No user accounts or API keys**: Agents pay from their own wallets; you don't manage users, keys, or invoices. * **Works everywhere**: Compatible with major hosts (e.g., Claude, Goose), local dev, and your own infrastructure. ## Build your first monetized MCP server <Steps> <Step title="Install the library"> Install the [ATXP server SDK](https://www.npmjs.com/package/@atxp/server) in your project: ```bash npm install @atxp/server ``` </Step> <Step title="Set up your wallet"> <a href="/server/create_a_wallet" target="_blank">Create an ATXP wallet</a> and set your wallet ID in an environment variable. The best way to do this is to create a `.env` file in the root of your project and add the following line: ```bash .env lines PAYMENT_DESTINATION=<YOUR_WALLET_ID> ``` <Warning> Never commit wallet address to version control. It is a good idea to add your `.env` to your `.gitignore` file to prevent it from being committed. ```bash echo .env >> .gitignore ``` </Warning> </Step> <Step title="Integrate with your MCP server"> Add the ATXP Express middleware to your MCP server: ```typescript // Import the ATXP SDK and other dependencies import { atxpServer, requirePayment } from '@atxp/server'; // [!code ++] import BigNumber from "bignumber.js"; // [!code ++] // Create your MCP server const server = new McpServer(); // Define your MCP tools... // server.tool(...); // Create and configure your Express server const app = express() app.use(express.json()) // Read your wallet ID from the environment variable const PAYMENT_DESTINATION = process.env.PAYMENT_DESTINATION // [!code ++] // Add the ATXP payment middleware // [!code ++] app.use(atxpServer({ // [!code ++] destination: PAYMENT_DESTINATION, // Your wallet ID // [!code ++] payeeName: 'Your Server Name', // The name of your MCP server // [!code ++] })) // [!code ++] // Other MCP server configuration... ``` </Step> <Step title="Add payment requirements to tools"> In each MCP tool exposed by your server that you want to charge per-use for, require payment before tool execution: ```typescript server.tool( "upcase", "Convert the provided string to uppercase", { text: z.string().describe("The text to convert to uppercase"), }, async ({ text }) => { // Require payment (in USDC) for the tool call // [!code ++] await requirePayment({price: BigNumber(0.01)}); // [!code ++] // Your tool's logic const result = text.toUpperCase(); // Return the result of the tool call return { content: [ { type: "text", text: result, }, ], }; } ); ``` </Step> <Step title="Connect to your MCP server"> Deploy your changes and connect to your MCP server with a host such as [Goose](https://block.github.io/goose/) or [Claude](https://claude.ai) to start paying for tool calls. <Tip> Running your MCP server locally?
