What the code does

We read the source, 3 d ago · rules 995398eba69f

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 an external command src/stdioRunner.ts:144

    const started = spawn(helperPath, ['serve'], { stdio: ['pipe', 'pipe', 'inherit'] })

Runs an external command swift/main.swift:876, [пакет] swift/main.swift:876

    typealias SetDisclaim = @convention(c) (UnsafeMutablePointer<posix_spawnattr_t?>, Int32) -> Int32

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.

Apple Calendar — questions

Answers built from our own checks of this server.

Why is there no uptime for Apple Calendar?

Apple Calendar 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 @redpop/apple-calendar-mcp was installed 73 times last week.

How do I connect Apple Calendar?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @redpop/apple-calendar-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Apple Calendar?

The npm package @redpop/apple-calendar-mcp was installed 73 times in the last week. Week over week that is +204%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Apple Calendar open source?

Yes — it is published under the MIT licence, written in TypeScript and 2 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
