Claude, with all your calendars

Claude's custom connectors take a remote MCP server URL. Add Synced and Claude on the web, on desktop and in Claude Code works with every Google and Outlook account you've connected, books meetings with a clash check and plans your tasks.

Connect Claude Why one connector

  • Web, desktop and Claude Code

    A connector added on claude.ai appears in the desktop app and in Claude Code when you're signed in.

  • Every account at once

    Google and Outlook, work and personal, merged.

  • Tasks and planning

    capture_task and plan_tasks turn "I need two hours for X by Thursday" into protected time.

Yes

Done. Both are blocked as busy on your Harbor, Northwind and Initech calendars.

Claude planning tasks through the Synced connector · sample data

Connect Claude

  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 the connector

    Customize → Connectors → Add custom connector, then paste the URL. On Team and Enterprise plans an owner adds it under Organization settings → Connectors, where the key can go in a request header instead of the URL.

  3. 3. Or from Claude Code

    Use the header form so the key stays out of the URL.

    claude mcp add --transport http synced https://api.meetsynced.com/functions/v1/mcp \
  --header "x-api-key: sk_live_your_key"

Server URL format:

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

Then ask

  • “Which calendars do you see?”
  • “What's on my calendars tomorrow?”
  • “I need 2 hours for the board deck before Thursday.”
