## Description

This MCP server provides deterministic tools to calculate Japanese train delay metrics. It determines if a delay meets the 5-minute threshold for a 'Chien Shoumeisho' (delay certificate) and categorizes the delay into Minor, Moderate, or Significant brackets. Use `calculate_delay_details` to get specific delay minutes and eligibility, `get_excuse_policy_info` to check which delay tiers are accepted for work or school, and `verify_certificate_integrity` to validate a certificate's unique hash.

## Tools

### calculate_delay_details
Calculates the core metrics of a train delay to determine if a certificate is warranted

### get_excuse_policy_info
Provides context on what types of delays are generally accepted by different sectors

### verify_certificate_integrity
Validates if a provided hash matches the expected deterministic identifier for a specific delay event
