# Your bookings. Your week at a glance. Source: https://corespeed.io/integrations/cal Connect Cal.com to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent reads your profile, event types, bookings and availability schedules, and answers what is booked this week and which working hours have no booking. It signs in with your own Cal.com account, and booking or cancelling a slot is a separate call that emails the attendee. ## Set up an agent Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)` It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect Cal.com after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up ## Know what is booked. See the gaps Ask your agent for this week's Cal.com bookings and the gaps in your working hours, in one answer. You ask your agent: "List my Cal.com bookings for this week and compare them with my working hours. Tell me which afternoons have no Cal.com booking. Do not book or cancel anything." It calls CoreSpeed: - `cal__list_bookings`: ok, 421 ms - `cal__get_schedules`: ok, 276 ms It reads from: Cal.com. ### This week: Five meetings, two afternoons without a booking. Five meetings booked. Monday and Thursday afternoons have no Cal.com booking, and Friday is off.

Yes. This page is about Cal.com, the open scheduling platform, connected to your agent through CoreSpeed. ### Can the agent book or cancel a meeting? Yes, as a separate tool call that emails the attendee. Approvals can hold it until a person agrees. How approvals work: https://corespeed.io/docs/approvals ### Does the agent check my other calendars? No. These tools read Cal.com bookings and availability schedules, not busy times from a calendar you connected to Cal.com. ### Does this replace my scheduling link? No. People still book through your Cal.com link. CoreSpeed lets your agent read what is booked and your working hours. ### Do I have to switch agents? No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once. ### Can my agent access every account in our organization? No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private. ### Does this work without connecting an account? No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data.
