Description: MCP server for summing two numbers
Latest version: 0.1.1

MCP Add Numbers Server
A Model Context Protocol (MCP) server to add two numbers using stdio transport.
Installation
Install the package globally or use npx:
npm install -g @aml-modelcontextprotocol/add-numbers

or
npx -y @aml-modelcontextprotocol/add-numbers

Usage

Create a config file (e.g., mcp-config.json) with the following content:

{
  "mcpServers": {
    "sum": {
      "command": "npx",
      "args": [
        "-y",
        "@aml-modelcontextprotocol/add-numbers"
      ]
    }
  }
}


Run the server using npx:

npx -y @aml-modelcontextprotocol/add-numbers


The server communicates via stdio. To test, use an MCP client (e.g., Claude) with the following JSON-RPC requests:

Initialize:
{
  "jsonrpc": "2.0",
  "id": 0,
  "method": "initialize",
  "params": {
    "protocolVersion": "2024-11-05",
    "capabilities": {},
    "clientInfo": {
      "name": "claude-ai",
      "version": "0.1.0"
    }
  }
}

Sum:
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "sum",
  "params": {
    "a": 5,
    "b": 3
  }
}

Response:
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": 8
}
