What is this? 🤔

This repository showcases:

• How to build an MCP server using Go 🐹.
• A simple and fun way to explore MCP Protocol 🎮.
• A starting point for your own custom MCP server adventures! 🌟

Tools 🌟

• hello, takes the parameters Submitter and Content.
• calculate, takes the parameters A and B. Example use is "calculate 2 and 4".

Quick Start 🚀

• Clone
• Install
• Build
• Run

1. Clone the repository:

   git clone https://github.com/your-username/hello-mcp-go.git
   cd hello-mcp
   

2. Install dependencies:

   go mod tidy
   

3. Build the project:

   go build -ldflags="-s -w" -o server.exe main.go
   

   or for Linux:

   go build -ldflags="-s -w" -o server main.go
   

   You will use this later when you want to consume it from Visual Studio Code.

4. Run the server:

   ./server
   

Consuming the Server with GitHub Copilot Agent Mode 🍴

1. Place yourself in mcp.json, make sure the server has been built (right now it's adjusted).

2. Adjust the "command" to point to the absolute path of your executable.

   {
     "servers": {
        "my-mcp-server-d73c20f3": {
            "type": "stdio",
            "command": "/path/to/your/executable"
        }
     }
   }
   

3. Open Copilot and select Agent in dropdown

4. Select the play icon.

   You should see the tool icon showing two tools.

5. Test it with a phrase like so "calculate 2 and 4". This should present a button that invokes the tool on the server.

Have Fun! 🎉

This project is all about learning and having fun. Feel free to experiment, break things, and create something amazing! 🌈
