Spark

Connect Claude to Spark on macOS or Windows to give your agent access to your emails. Ask about your inbox, then let Claude do the work — read threads, organize your inbox, and draft replies without leaving the conversation. Tools are discovered dynamically when Spark Desktop is running, so Claude always sees what’s actually available. Key Features: • **Connect any account** — Give Claude access to any Spark email account, including Gmail, Outlook, Exchange, iCloud, Yahoo, and IMAP. • **Read and search your workspace** — Browse and search emails, list folders, read full threads with bodies and attachments, look up contacts, and review meeting transcripts. • **Check schedules and availability** — Look up calendar events and find mutual availability with teammates. • **Manage your calendar** — Create, update, delete, and RSVP to events, and invite or remove attendees (send access). • **Compose, send, and share drafts** — Create new emails, replies, and forwards (with attachments or from saved templates), send them now or schedule them for later, and share them with teammates for review. • **Triage conversations** — Archive, pin, snooze, move, label, mark as done, share with the team, and assign or delegate messages. • **Organize and manage** — Reclassify smart categories and manage contacts (block/accept, set category, mark important/primary, toggle auto-summary). • **Collaborate in context** — Post team chat comments on shared threads. **Access and Permissions**: Each account and shared inbox has its own access level — read-only, triage, or send — configurable in Spark Desktop > Settings > AI Agents. Write access (drafting, triage, and contact management) and send access (sending drafts and managing calendar events) are only available where you’ve enabled them.

Score explained

How the Discoverability Score works

The Claude Discoverability Score will be the percentage of contested conversations where Spark appears in the connector picker or Claude invokes it directly. Found and Positioned will be shown as diagnostics, not score inputs.

InvisibleBuriedEmergingCompetitiveWinning

Organic discovery scoring is pending. Your Connector score will appear on this scale when measurement goes live.

FoundDiagnostic

Whether Claude found your Connector in connector search. It must be Found before it can reach the picker, but the score counts picker appearances—not search results.

PickedMain score

How often your Connector appeared in the picker, or Claude invoked it directly, across contested conversations. This percentage is the Discoverability Score; the headline number is rounded.

PositionedDiagnostic

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
