Microsoft 365 calendar events and attendees join the relationship graph alongside email, calls, and CRM.
Clearskies is the MCP server for Outlook Calendar. Connect Outlook Calendar once. Claude, ChatGPT, Cursor, n8n, and any other MCP-compatible AI query Outlook Calendar data — resolved into a unified customer context graph — through a single Model Context Protocol endpoint.
Yes. Clearskies is the MCP server for Outlook Calendar. Connect Outlook Calendar once and any MCP-compatible AI — Claude, ChatGPT, Cursor, n8n, and others — can query Outlook Calendar data through a single endpoint, resolved into a unified customer context graph.
Sign up at app.clearskies.cc, authorize Outlook Calendar via OAuth, and add the Clearskies MCP server to Claude. Claude will then have access to Outlook Calendar data alongside the rest of your connected stack. Setup takes minutes. Auth is OAuth (Microsoft 365 admin install).
Connect Outlook Calendar to Clearskies, then point ChatGPT (or any custom GPT / agent) at the Clearskies MCP endpoint. ChatGPT sees the same resolved customer context graph that Claude does — accounts, contacts, deals, and activity from Outlook Calendar alongside calls, email, calendar, and Slack.
Clearskies reads: Calendar events and attendees across the org; Internal vs. external attendee resolution; Meeting cadence per account and deal. It does not write back to Outlook Calendar; the integration is read-only.
