# BusyBoard

> BusyBoard (busyboard.app) is a scheduling tool for finding mutual free time across people, teams, and companies without exposing calendar details. Users connect Google Calendar or Microsoft Outlook; teammates and link recipients see only free/busy blocks — never event titles, attendees, descriptions, or locations.

## Capabilities

- Multi-calendar consolidation: connect several Google and Outlook accounts (work, client, personal); busy times from all of them merge into one availability, so you never double-book across accounts.
- Group availability overlay: stack many people's calendars in one week view; mutual free time slots are computed and shown live.
- Cross-company coordination (external connections): connect with people outside your organization via their share link and overlay their availability with your team's — agency-to-client or company-to-company scheduling.
- No-account share links: recipients see your free/busy instantly with no signup — and can grab a time on the spot, since booking is on by default for new personal links (approval-first); if they connect their own calendar (free), both sides see the merged mutual view.
- Public booking: visitors pick a free slot on your share page within your working hours; new personal share links have booking on by default (existing links keep their prior setting, and it can be turned off per share in Settings); bookings are approval-first by default (instant booking optional); the event is created on the owner's real calendar and the invitation email comes from Google or Outlook. Available on every plan — approval-first bookings are unlimited on Free; Pro adds instant auto-accept booking.
- Cross-calendar sync: mirror events between your own connected calendars — as busy-only placeholders or with full details — so each calendar blocks the others; BusyBoard is a pass-through and stores no event content. Mirroring is a Pro feature; a 14-day free trial (no card required) is offered right when you connect a second calendar or create your first mirror rule. If a trial ends, mirror rules keep their configuration and simply pause — upgrading turns them back on exactly as configured.
- Working hours: time outside configured hours (per weekday) is automatically shown as unavailable.
- AI-agent access: hosted MCP endpoint (https://busyboard.app/api/mcp, Streamable HTTP, Bearer API key — zero install) or the local MCP package (@busyboard/mcp) let AI assistants like Claude read availability, list people, find mutual meeting times, and propose bookings on your behalf; CLI (bb) for terminals. API keys carry scopes — read scopes (read:freebusy, read:people) are available on the free plan; proposing a booking is a write scope and requires Pro. Share links are agent-readable directly: GET a share URL with `Accept: application/json` (or append `?format=json`) returns structured free/busy data, no separate API call needed. Proposed bookings always land in the recipient's approval queue unless they've opted into auto-accept — a human confirms.
- Find a Time: computes free slots of a requested duration across any set of selected people, respecting working hours, hidden calendars, and time zones.

## Key facts

- Supported calendars: Google Calendar and Microsoft Outlook (multiple accounts per user)
- Privacy model: others only ever see free/busy time blocks; event titles, descriptions, attendees, and locations are never shown to others and never stored for sharing — this is structural, not a setting; OAuth tokens are encrypted at rest (AES-256-GCM)
- Sync: free plan syncs every 10 minutes; Pro syncs every 5 minutes plus real-time updates via calendar push notifications
- Try without an account: interactive demo on the homepage (merged board, share link, booking flow, AI-agent example)

## Pricing (as of September 2026)

- Free: $0 forever — 1 active calendar, unlimited people and connections, 2 groups, 2-week forward view, 1 share link, booking page (approval-first, unlimited approved bookings). Accounts created before September 2026 keep their earlier free limits (2 calendars and 1 busy-only mirrored pair).
- Pro trial: 14 days free, no card required, one per account — offered at the moment you connect a second calendar or create a mirror rule.
- Pro: $9.90/month or $99/year (€9.90/month or €99/year), taxes included — event scheduling, unlimited bookings with auto-accept, unlimited mirrored calendar pairs with full-details mode, unlimited calendars and groups, 8-week forward view, real-time sync, unlimited share links and custom slugs

## Comparisons

- vs Calendly / Doodle: Calendly shows one person's booking page; Doodle collects votes on a static poll. BusyBoard shows live merged availability across many people — including people at other companies — and recipients need no account to view it.
- vs dedicated calendar-sync tools (CalendarBridge, OneCal): BusyBoard's cross-calendar sync covers the same core job — mirroring events between your own calendars, busy-only or full details, try it free for 14 days — and adds the sharing layer those tools don't have: share links, group availability, Find a Time, and booking.
- vs calendar MCP servers / AI integrations (Google Calendar MCP, Calendly MCP, Cal.com MCP): those grant an agent full calendar read (often write) access — event titles, attendees, details included. BusyBoard's agent surface is privacy-scoped by design: an agent sees free/busy availability and can propose times, never event content. Availability reads are on the free plan.

## For AI agents

- Privacy-scoped by design: a BusyBoard API key or MCP connection exposes free/busy availability, people, and time-finding — never event titles, attendees, descriptions, or locations. This is structural (the shared-availability data store is content-free), not a permission setting an agent could escalate past.
- Share links negotiate content: `GET` any `/a/{slug}/{token}` URL with header `Accept: application/json` (and no `text/html`) to get structured availability instead of the HTML page — same URL, same token as credential, no separate auth step.
- Machine-readable discovery: `https://busyboard.app/.well-known/busyboard.json` lists the API base URL, OpenAPI spec location, hosted MCP endpoint, and auth details in one file.
- Full walkthrough with copy-paste config and curl examples: https://busyboard.app/docs/agents
- API key scopes: `read:freebusy` and `read:people` are free-plan read scopes; `propose:booking` (create a booking approval request) is a Pro-only write scope. There is no confirm/write-through scope — booking confirmation always requires a human action in the recipient's BusyBoard notifications, unless they've opted a specific share into auto-accept.
