What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs a command on install [пакет] package.json:1
postinstall: node lib/postinstall.js
File ships in the package but is absent from the source [пакет] bin/cli.js:1
этот файл ставится пользователю, но в репозитории его нет
In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Builds a database query by concatenation .github/workflows/release.yml:98
      - name: Update package version
        working-directory: npm-package
        run: npm version ${{ steps.version.outputs.version }} --no-git-tag-version --allow-same-version
Touches key and credential files .github/workflows/release.yml:109
      - name: Strip stale auth from .npmrc (OIDC handles auth)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add icloud-calendar-mcp -- npx -y @icloud-calendar-mcp/server
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "icloud-calendar-mcp": {
      "args": [
        "-y",
        "@icloud-calendar-mcp/server"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.icloud-calendar-mcp]
command = "npx"
args = ["-y", "@icloud-calendar-mcp/server"]
.cursor/mcp.json
{
  "mcpServers": {
    "icloud-calendar-mcp": {
      "args": [
        "-y",
        "@icloud-calendar-mcp/server"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "icloud-calendar-mcp": {
      "args": [
        "-y",
        "@icloud-calendar-mcp/server"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: ICLOUD_USERNAME (Your Apple ID email (e.g., [email protected])), ICLOUD_PASSWORD (App-specific password for iCloud (not your main Apple ID password)). The author declared them in the registry entry; get the values from the project itself.

Icloud Calendar MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Icloud Calendar MCP?
Icloud Calendar MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @icloud-calendar-mcp/server was installed 123 times last week.
How do I connect Icloud Calendar MCP?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @icloud-calendar-mcp/server straight from npm; nothing to host, nothing to sign up for.
How many people use Icloud Calendar MCP?
The npm package @icloud-calendar-mcp/server was installed 123 times in the last week. Week over week that is +42%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Icloud Calendar MCP open source?
We cannot say either way: written in Kotlin and 18 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
