Inday Public Holiday API
Wire public holiday and working-day logic into agents while building schedulers, billing cutoffs, or launch calendars for 30+ countries.
Overview
io.github.gokhanibrikci/inday-holiday-api is a MCP server for the Build phase that lets agents query public holidays and working-day calendars for 30+ countries through Inday’s HTTP MCP endpoint.
What is this MCP server?
- Inday Public Holiday API exposed as MCP at https://inday.co/api/mcp (streamable-http)
- Public holiday data for 30+ countries via assistant-callable tools
- Working-day and calendar checks for scheduling and compliance UX
- Free API key signup at inday.co/signup (X-API-KEY header)
- Version 1.0.0 remote server—no local npm install required
- 30+ countries coverage (per server description)
- Remote URL: https://inday.co/api/mcp
- Server version 1.0.0
What problem does it solve?
Hard-coding country holidays in prompts or spreadsheets breaks quickly and wastes ship time whenever markets or rules change.
Who is it for?
Builders adding multi-country calendars, SLA timers, or payroll-like cutoffs who want the agent to call a maintained holiday API.
Skip if: Products that only need a single static holiday list with no API budget, or teams blocked from sending calendar queries to a hosted third party.
What do I get? / Deliverables
After you add your Inday X-API-KEY and register the remote MCP URL, the assistant can fetch holiday and working-day data while you design features and integrations.
- Agent-callable holiday and working-day lookups for 30+ countries
- Reduced manual holiday spreadsheet maintenance during feature work
- Integration blueprint using Inday’s MCP remote URL

Journey fit
Holiday APIs are integrated during product construction—cron jobs, HR tools, and checkout windows—not only at launch marketing time. Remote streamable-http MCP with X-API-KEY is a hosted integration pattern agents call like any other external API.
How it compares
Hosted holiday-data MCP remote—not an Obsidian note plugin or a generic timezone-only library.
