Example of MCP server in Typescript

A basic example of an MCP server in Typescript running over HTTP.

It gives you the list of the drinks or you can ask to order one particular.

How to use it

Start the server by building and running it:

npm run build
npm start

Or, in one shot, use npm run start:build.

You can also start in development mode with npm run dev, which will watch for changes.

The server will be running on http://localhost:3000.

How to test it

You can use a tool like curl to send JSON-RPC requests to the server.

1. Initialize

This request initializes the connection with the server.

curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}' http://localhost:3000

2. List Tools

This request asks the server for the list of available tools.

curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}' http://localhost:3000

3. Execute a Tool (getDrinkNames)

This request executes the getDrinkNames tool to get a list of all drink names.

curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":3,"method":"tools/execute","params":{"name":"getDrinkNames","arguments":{}}}' http://localhost:3000

4. Execute a Tool (getDrink)

This request executes the getDrink tool to get information about a specific drink.

curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","id":4,"method":"tools/execute","params":{"name":"getDrink","arguments":{"name":"Latte"}}}' http://localhost:3000
