# The Calendar integrations

Connect The Calendar to any other app, or use it from your AI client over MCP. The Calendar publishes date-based reference data as static JSON files covering public holidays and event schedules. Callers can list public holidays for a given year by country across roughly 30 countries and by individual US state, and retrieve sports season calendars and finance-market date calendars such as market holidays. Responses are plain JSON documents fetched by country, state or year path. No credentials required.

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

## What do you want to automate with The Calendar?

Give your AI client this address.

`https://mcp.apiant.ai`

One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

### Set it up in your client

### Claude Code

Run this in the directory you want to work in.

`claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai`

Start Claude Code there, approve the server, and sign in in the browser page it opens.

[Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code)

### Claude, web and desktop

Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Cursor

Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Zed

Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Codex and the ChatGPT desktop app

Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Any other MCP client

Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

## What our customers say

Questions

## The Calendar, answered

###

### Is there a The Calendar MCP server?

APIANT's MCP server at https://mcp.apiant.ai works with The Calendar. Add that address to any AI client that takes a remote MCP server and sign in once in your browser. Your client can then run The Calendar actions on demand, or have APIANT build, test and run automations that use The Calendar. Nothing to install.

###

### What can your agent do in The Calendar?

Any of The Calendar's 5 actions, including Get country holidays, Get finance calendar, Get sports schedule and Get US federal holidays. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can I use The Calendar directly from Claude, ChatGPT or Cursor?

Yes. Connect your AI client to APIANT once and it works with The Calendar two ways. Ask it to do something in The Calendar once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running on its own. A one-off action uses your plan's tasks the same way an automation step does.

###

### Do I need to write code against the The Calendar API?

No. APIANT connects to the The Calendar API for you. Describe what you want in plain language and your agent builds it on the The Calendar triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the The Calendar API documentation and adds it.

###

### Which apps can The Calendar connect to?

Any app in the catalog; the list on this page pairs The Calendar with each of them. If the other app is missing, point your agent at its API documentation and it builds the connector.

###

### What happens when something fails?

Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.

###

### Is there a free plan?

Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
