Leave Management MCP Server

Overview

The Leave Management MCP Server is a lightweight, Python‑based Model Context Protocol service that turns an Excel workbook into a fully queryable data source for AI assistants. Its primary purpose is to let Claude or any MCP‑compatible client retrieve, filter, and analyze employee leave records without exposing raw spreadsheet files. By converting the workbook into a structured API, developers can embed sophisticated leave‑tracking logic directly into conversational workflows, enabling dynamic responses such as “How many vacation days does Alice have left?” or “Show me all employees who are on leave next week.”

At its core, the server reads an Excel file (e.g., ) that contains a sheet named Leaves‑2025 with columns for employee identifiers, names, locations, and monthly leave balances. The MCP exposes a set of tools that perform common operations:

• Query – fetch leave balances for a specific employee or department.
• Summarize – calculate totals, averages, or outstanding leave days across the organization.
• Alert – identify employees approaching their leave limits or those with unusual patterns.

These tools are wrapped in MCP endpoints, allowing an AI assistant to call them with natural language prompts. For example, a user could ask the assistant, “Which employees in Bangalore have taken more than 10 days of sick leave this year?” The assistant translates that request into a tool invocation, receives the structured result, and returns it in conversational form. This tight integration eliminates manual spreadsheet manipulation, reduces errors, and speeds up decision making.

Key features that make this MCP valuable for developers include:

• Zero‑code data integration – only the Excel file and a simple configuration are required; no database setup.
• Built‑in data validation – the server checks sheet names and column headers, ensuring consistency before exposing data.
• Extensible model layer – the module defines clear data models that can be expanded to include additional attributes (e.g., hire date, role).
• Portable deployment – the server can run locally via or be registered in Claude Desktop, VS Code, or any other MCP client.

Real‑world scenarios where this server shines include HR chatbots that automatically report leave balances, compliance dashboards that flag potential policy violations, and internal tools that allow managers to quickly query team availability during peak periods. By providing a clean, protocol‑driven interface to existing Excel data, the Leave Management MCP Server turns static spreadsheets into a dynamic, AI‑ready resource.
