Happy Platform MCP v5.1 Installation

Overview

Install Happy Platform MCP v5.1, register one or more ServiceNow instances, and connect an MCP host without exposing authentication material to the model, MCP messages, logs, shell history, or client JSON.

Prerequisites

• Node.js >= 20

• A local interactive terminal for masked prompts
• An OS keychain available to the current user
