## Why update_absence is rated Medium

This tool creates or modifies leave/absence data reversibly. While it could cause business disruption if misused (e.g., removing an employee's approved leave), the operation is reversible through subsequent updates. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read).

From the tool's own definition: "Tool name 'update_absence' and description 'Update an existing leave or absence record in Sanka' indicate modification of existing data (leave/absence records)."

## Use case

AI agents use update_absence to create or update resources in Sanka MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sanka MCP Server environment.
