What is the Holiday API MCP Server?

Empower your AI agent to orchestrate your entire global event and holiday research workflow with Holiday API, the reliable source for holiday data. By connecting Holiday API to your agent, you transform complex calendar auditing into a natural conversation. Your agent can instantly retrieve public holidays for any country, audit workday counts, and identify supported languages without you ever touching a manual calendar. Whether you are planning international logistics or managing global payroll, your agent acts as a real-time event consultant, ensuring your schedules are always accurate and compliant.

What you can do

  • Holiday Auditing — Retrieve public and federal holidays for over 200 countries and retrieve detailed metadata, including names and dates.
  • Workday Oversight — Calculate the next workday or count workdays between two dates to maintain a clear view of operational periods.
  • Global Discovery — List all supported countries and languages in the Holiday API catalog to identify regional event markers.
  • Temporal Intelligence — Query holidays for specific years to audit past and future global events instantly.
  • Usage Monitoring — Get real-time API usage and status metadata to maintain strict control over your research volume.

How it works

  1. Subscribe to this server
  2. Enter your Holiday API Key
  3. Start managing your event intelligence through Claude, Cursor, or any MCP-compatible client

Who is this for?

  • Logistics Managers — monitor international holidays and retrieve workday metadata straight from your workflow.
  • HR Specialists — verify global public holidays and audit payroll cycles without manual searching.
  • Travel Planners — perform rapid audits of local events and identify peak holiday periods through natural language.
  • Operations Leads — automate holiday data querying to orchestrate cross-functional global teams smoothly.

Why VS Code Copilot?

GitHub Copilot Agent mode brings Holiday API data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 5 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.

  • VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor

  • Project-scoped MCP configs (.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access

  • Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop

  • GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

FAQ

Frequently asked questions

01

How do I find my Holiday API Key?

Log in to your Holiday API dashboard, and you will find your API Key on the main page. Copy and paste it below.

02

Does the agent support historical years?

Yes. Holiday API provides historical data. Depending on your plan, you can query holidays for past years to audit previous events.

03

Can the agent calculate the number of workdays?

Yes. The get_workdays_count tool allows your agent to calculate the exact number of non-holiday business days between two dates for any country.

04

Which VS Code version supports MCP?

MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.

05

How do I switch to Agent mode?

Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.

06

Can I restrict which MCP tools Copilot can access?

Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.

07

Does MCP work in VS Code Remote or Codespaces?

Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.

08

MCP tools not available

Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
