Overview

Holiday Calendar is a Model Context Protocol server that provides U.S. federal holidays with observed dates and business-day math capabilities. Any MCP-compatible AI assistant can call Holiday Calendar's tools directly, letting the model decide when to use them during conversations or agent runs.

The server runs as a hosted remote service at https://starter.modernmustardseed.com/holidays with no local installation required. Version v1.0.0 is available now, and authentication is not needed to connect.

Holiday Calendar is categorized under Productivity on mcp.site and integrates with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to verify ownership and keep information up to date.
