Overview

This server implements the Model Context Protocol to provide Claude with structured access to employee data and HR operations.

The HR MCP Server enables Claude to:

• Look up detailed employee information
• Search for employees by various criteria
• Submit and manage global leave requests
• Translate text with HR/HCM context awareness

For a detailed architectural overview, see ARCHITECTURE.md.

Tools

The server provides the following tools to Claude:

1. get_employee_info

Retrieves detailed information about a specific employee by ID, including personal details, employment information, skills, benefits, and more.

2. search_employees

Search for employees by various criteria with flexible matching options. Supports searching by name, department, skills, location, and many other fields.

3. request_global_leave

Submit global leave requests for employees traveling to multiple countries, with approval chains and compliance reminders.

4. Translation Prompt: translate_text

Translates text from any language to a specified target language with automatic source language detection and special focus on HR/HCM terminology.

The translation system handles HR-specific terminology with contextual awareness, preserving the technical meaning of terms like "benefits," "period," "check," "position," etc., which have special meanings in Human Capital Management contexts.
