Vamoose

Vamoose is a local calendar workflow engine that lets an assistant book time off, create holds and events, and advance approval workflows across Google, Outlook

What you can do

Create holds, out-of-office blocks and plain events on a connected calendar, optionally inviting attendees or a manager for approval. Run built-in or custom workflows such as time off, notify-only and away, and advance them when the manager accepts. Check approval status, promote an approved hold to the team as optional attendees, or cancel a hold and notify everyone. Look up coverage for a date range and read remaining leave balance when an HR system is configured. Review run history and define workflows as JSON files.

When to use it

Useful when you want an assistant to handle recurring calendar busywork such as requesting time off, blocking out-of-office time, or running a multi-step approval flow, especially across more than one calendar account. Best for people whose calendar backend is Microsoft Graph, Google, iCloud or CalDAV.

Requirements

Runs as a local process (Homebrew, Scoop, Docker or Go install) and is started as the vamoose binary with the mcp argument. Authenticate once first so a cached token exists. One calendar backend must be configured via VAMOOSE_PROVIDER, with provider credentials such as VAMOOSE_CLIENT_ID and VAMOOSE_TENANT, VAMOOSE_GOOGLE_CLIENT_ID and VAMOOSE_GOOGLE_CLIENT_SECRET, or VAMOOSE_ICLOUD_USERNAME and VAMOOSE_ICLOUD_APP_PASSWORD. HR balance and leave filing need BambooHR or webhook settings. VAMOOSE_GO
