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.

File ships in the package but is absent from the source [пакет] shared/utils/calendar-helpers.js:1, [пакет] shared/tools/create-event.js:1, [пакет] shared/tools/delete-event.js:1 и ещё 10

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

This one needs environment variables set before it will start: GCAL_SERVICE_ACCOUNT_CLIENT_EMAIL (Service account email address from Google Cloud Console.), GCAL_SERVICE_ACCOUNT_PRIVATE_KEY (Service account private key in PEM format from Google Cloud Console.), GCAL_IMPERSONATE_EMAIL (Email address of the user whose calendar to access via domain-wide delegation.), ENABLED_TOOLGROUPS (Comma-separated list of tool groups to enable (readonly or readwrite).). The author declared them in the registry entry; get the values from the project itself.

Google Calendar — questions

Answers built from our own checks of this server.

Why is there no uptime for Google Calendar?
Google 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 google-calendar-workspace-mcp-server was installed 101 times last week.
How do I connect Google Calendar?
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 google-calendar-workspace-mcp-server straight from npm; nothing to host, nothing to sign up for.
How many people use Google Calendar?
The npm package google-calendar-workspace-mcp-server was installed 101 times in the last week. Week over week that is -12%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Google Calendar open source?
Yes — it is published under the MIT licence, written in TypeScript, 80 stars on GitHub and 26 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
