How do I list all the holidays for a specific country in 2024?

Simply ask the agent to `list_holidays` and provide the Country code (e.g., 'US' or 'BR') and the year '2024'. It will retrieve the full list from Calendarific.

Can I filter holidays by type, like only religious holidays?

Yes! Use the `list_holidays_by_type` tool and provide the country, year, and type (e.g., 'religious'). Your agent will return only the matching observances.

How do I see which countries are supported by Calendarific?

Use the `list_supported_countries` tool. It will retrieve the complete directory of over 230 countries currently available in the Calendarific API.

Calendarific + AutoGen FAQ

Common questions about integrating Calendarific MCP Server with AutoGen.

How does AutoGen connect to MCP servers?

Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call Calendarific tools during their conversation turns.

Can different agents have different MCP tool access?

Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
