This is a leave management system server based on the Model Context Protocol (MCP). It allows AI assistants (such as Claude, Cursor) to act as HR collaborators, automatically completing the entire process of collecting leave information, verifying company policies, automatically approving requests, and generating user - friendly confirmation notifications. The system is built using Python and the fastmcp framework, with built - in verification rules and audit trails, aiming to replace traditional manual processes and provide secure and composable HR automation operations for AI agents.
