AU Agent Utilities MCP server

AU Agent Utilities

Reliable Australian utility tools for AI agents.

The first module is the Australian Business Day Engine — deterministic business-day, public-holiday and deadline calculations across all Australian states and territories.

Instead of asking an AI model to guess whether a date is a business day, the agent can call a tool and get a structured answer.
