   Ask your AI app to use Calendly, then open Activity to see the call.

Calendly's own MCP server

• ContextGate now connects to Calendly's own MCP server by default: in Add Connection, search for Calendly and sign in with your Calendly account. There's nothing to copy or paste.
• ContextGate's app connector for Calendly is still there, under Ways to connect on the same card.
• Whichever way you connect, your tool switches, policies and Activity work the same.

What you get with Calendly and ContextGate

• Your AI apps can use CalendlyClaude, Cursor, ChatGPT and other AI apps reach Calendly through the one ContextGate connection you add to them.
• You choose which tools they can useSwitch off any Calendly tool you don't want used. It's hidden from your AI apps and refused if called.
• Every call is checked and recordedYour policies check each call (for example, personal data is hidden and secrets are blocked), and Activity keeps a record of it.

ContextGate sees only the tool calls that go through it, not your AI app's built-in tools or your chats.
