Can I use Google Calendar as a CLI?

Yes. KosmoKrator exposes a Google Calendar CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose Google Calendar through MCP?

Yes. The KosmoKrator MCP gateway can expose selected Google Calendar tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are Google Calendar credentials stored?

Google Calendar credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for Google Calendar MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

Use this integration from Lua code mode, the headless integrations CLI, or the KosmoKrator MCP gateway. The same package metadata powers all three surfaces.
