HRizzle HR Assist

👔 HRizzle | AI-Powered HR Assistant

MCP-based HR automation tool that streamlines employee onboarding, leave management, and equipment requests.

Architecture: MCP Server + Claude Desktop   |   Package Manager: UV   |   Features: 8 Tools + Onboarding Prompt

A Model Context Protocol (MCP) implementation that transforms Claude Desktop into an intelligent HR assistant. Manages the complete employee lifecycle from onboarding to daily HR operations through natural language conversations.

---

HRizzle-HR-Assist is an MCP-based HR automation system that integrates with Claude Desktop to provide conversational HR management. It handles employee onboarding, meeting scheduling, leave applications, equipment requests, and manager assignments through a dummy HRMS API mimicking Keka's interface. The system uses Pydantic for data validation, smtplib for email automation, and FastMCP for protocol-compliant tool exposure.

---

Features

• Conversational Employee Onboarding: Multi-step onboarding workflow using MCP prompts that adds employees, sends welcome emails, assigns managers, and creates equipment tickets.
• Intelligent Leave Management: Apply for leave, check leave balance (20-day default), and retrieve leave history with automatic date validation.
• Meeting Coordination: Schedule meetings with conflict detection, view upcoming meetings, and cancel existing meetings with topic matching.
• Equipment Request Ticketing: Create IT helpdesk tickets for equipment (Laptops, Monitors, etc.) with status tracking (Open/In Progress/Closed).
• Fuzzy Name Search: Resolve employee names to IDs using difflib matching for natural language interactions.
• Email Automation: SMTP-based email notifications for onboarding, meeting invites, and status updates via Gmail integration.
• Manager Hierarchy: Assign managers and fetch direct reports with organizational structure validation.
• Seeded Dummy Data: Pre-populated with 8 employees across Engineering and Product teams for immediate testing.
