Student Leave MCP App With Github Copilot Agent

mcp-student-leave-copilot-ab (<domain>-student-leave-<client>-ab)

A lightweight MCP server in Node.js, integrated with Github Copilot, to manage student leave requests and approvals.

Getting Started

Create a project

mkdir mcp-student-leave-copilot-ab

cd mcp-student-leave-copilot-ab

npm init -y

npm i @modelcontextprotocol/sdk zod

node server.js

Student Leave MCP server (stdio) and Github Copilot agent ready!

Create server.js

Add npm scripts (optional)

{
  "type": "module",
  "scripts": {
    "start": "node server.js"
  }
}

Wire it up in Github Copilot (VS Code)

Github Copilot looks for MCP servers in its mcp.json

/Users/abhijeetgiram/Library/Application Support/Code/User/mcp.json

{
  "servers": {
    "mcp-student-leave-copilot-ab": {
      "command": "node",
      "args": [
        "/Users/abhijeetgiram/Workspace/Personal/mcp-student-leave-copilot-ab/server.js"
      ],
      "alwaysAllow": ["list_students", "get_student_details", "approve_leave"],
      "disabled": false
    }
  }
}

Use it from Github Copilot

In a Github Copilot chat, just ask things like:

• “Show me the student list.” → Github Copilot calls list_students

• “Get details of E002.” → Github Copilot calls get_student_details with { id: "S002" }

• “Approve leave L1002 for E002.” → Github Copilot calls approve_leave with { studentId: "S002", leaveId: "L2002" }

Model Context Protocol (MCP)

• It’s a new open standard by Anthropic that defines how AI models, tools, and apps can talk to each other.

• Think of it like a “plugin protocol” for AI assistants.

• MCP Server = Your code (like the student leave manager we built).

• MCP Client = Something that talks to the server (Github Copilot, Cline, Claude, or any AI agent).

• They communicate over:

  • stdio (local processes, great for Github Copilot in VS Code)
  • or HTTP/WebSocket (remote deployment, so web apps / React can call it).

• MCP turns your Node.js script into a “tool plugin” for AI assistants.
