Boilerplate Paid MCP Server

An example paid MCP server using PaidMCP and the official MCP TypeScript SDK

This MCP server is designed to be used in combination with Alby Bitcoin Payments MCP Server or another MCP Server that can make lightning payments.

Tools

This boilerplate MCP server has 3 tools:

• get_weather is a paid tool to fetch the weather in a given city
• get_food_delivery_menu is a free tool that returns food items that can be purchased
• order_food_delivery order one or more items from the menu

Examples

1. Weather

What's the weather in Wellington?

I'll get the current weather information for Wellington for you.
─── get_weather | weather ──────────────────────────
city: Wellington

It looks like this weather service requires a small Lightning payment to access the data. I can help you pay this invoice using your connected Lightning wallet if you'd like to proceed.

The invoice is for 21 sats to get weather data for Wellington. Let me pay this invoice and then get your weather information.
─── pay_invoice | alby-http ──────────────────────────
invoice: ...


◇  Goose would like to call the above tool, do you allow?

Great! Payment successful. Now let me get the weather information for Wellington using the payment hash.
─── get_weather | weather ──────────────────────────
city: Wellington
payment_hash: ...

## Weather in Wellington

The current temperature in Wellington is **14.2°C** (about 57.6°F).

*This weather data was obtained via a Lightning micropayment of 21 sats.*

2. Food Delivery

Order me 2 pizzas

The user wants to order 2 pizzas. Looking at the environment details, I can see this is a boilerplate MCP project with food delivery functionality. I can see there are food delivery tools available:

food_delivery_menu.ts
food_delivery_order.ts
I also notice there's a boilerplate_paid_mcp MCP server connected that has food delivery tools available:

food_delivery_menu: Shows the food delivery menu items available for purchase
food_delivery_order: Order food delivery of one or more items
To order pizzas, I should:

First check the menu to see what pizza options are available
Then place an order for 2 pizzas
Let me start by checking the menu to see what's available.

I'll help you order 2 pizzas. Let me first check the food delivery menu to see what pizza options are available.

─── boilerplate_paid_mcp | get_food_delivery_menu ──────────────────────────

{}

Perfect! I can see there's Pizza available on the menu for 21 sats each. Now I'll place an order for 2 pizzas.

─── boilerplate_paid_mcp | order_food_delivery ──────────────────────────

Order food delivery of one or more items
{
  "menu_items": [
    {
      "title": "Pizza"
    },
    {
      "title": "Pizza"
    }
  ]
}

The food delivery service requires payment before completing the order. I need to pay the lightning invoice first. Let me pay the invoice for 42 sats (21 sats × 2 pizzas) using the Alby MCP server.


─── alby_mcp | pay_invoice ──────────────────────────

{
  "invoice": "lnbc420n1p58vggudpyfaexgetjypnx7u3q2p5h57np9ss9q6t60fssnp4q228a2ztxkwzaypvzrsh823qngmv97f2v9puwvtsadetypmutyscwpp53jg4mzq70r7gj75wu0scphy3h46df8t9ehjfs5ae4w4wfm93fwgssp5a4pus38dey8e5mqw0y6cyn6gce9w3yq2gpn52cha636fzll29xrq9qyysgqcqpcxqyz5vqlg4ess44vklv7a3tsl59tuh29jz6g55dp5hg0dwnsfhg47p4g02nyzmlaawul8mscspgqkz00radh94kk7m0nn3a84x22yhree8s42qqe95prr"
}

Great! The payment was successful with no fees. Now I'll complete the pizza order by providing the payment hash.

─── boilerplate_paid_mcp | order_food_delivery ──────────────────────────

{
  "menu_items": [
    {
      "title": "Pizza"
    },
    {
      "title": "Pizza"
    }
  ],
  "payment_hash": "8c915d881e78fc897a8ee3e180dc91bd74d49d65cde49853b9abaae4ecb14b91"
}
