ChatGPT, with every calendar you use

ChatGPT can use MCP servers as custom connectors. Add Synced and ChatGPT works with every Google and Outlook account you've connected to Synced, so it can see your real week, book across companies and keep your task list.

Connect ChatGPT Why one connector

  • One connector, every account

    Google and Outlook, work and personal, merged into one calendar.

  • Booking with a clash check

    A clashing time is refused until ChatGPT confirms with you.

  • Plans that wait for a yes

    Task plans are previewed first and only written when you agree.

Booking a meeting through the Synced connector · sample data

Connect ChatGPT

  1. 1. Create a Synced API key

    In Synced, open Settings → Integrations and choose Generate New API Key. Copy the MCP Server URL shown under it; it already contains the key, so treat it like a password.

  2. 2. Add a custom connector

    Where your ChatGPT plan offers custom connectors (developer mode), create a connector with the URL and no extra authentication. Menu names differ by plan.

  3. 3. Use it in a chat

    Pick the Synced connector in the conversation and ask about your calendar.

Server URL format:

https://api.meetsynced.com/functions/v1/mcp?api_key=sk_live_your_key

Then ask

  • “Find 30 minutes with priya@acme-retail.com next week and book it.”
  • “Which calendars do you see?”
  • “Plan my open tasks for this week.”
