How to connect Calendly to ChatGPT

1. 1. Enable Calendly in Metorial

   In your Metorial portal, enable the Calendly MCP server and sign in with the account that owns the data. Access stays governed by your team policies.

2. 2. Add a custom MCP server

   On ChatGPT web, open Plugins, select +, then Add custom MCP server.

3. 3. Paste your Metorial MCP URL

   Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>), choose OAuth and accept the risk notice.

4. 4. Create and install the plugin

   Select Create as a plugin, install it and sign in to load Calendly tools.

• Cancel Event: Cancel a scheduled Calendly event.
• Get Event Details: Retrieve detailed information about a specific scheduled event, including its invitees.
• Check Availability: Check available time slots for a specific event type, retrieve a user's busy times, or list availability schedules.
• Get User: Retrieve a Calendly user's profile information.
• List Scheduled Events: List scheduled events (meetings) for a user or organization.
• List Event Types: List event type templates (e.g., "30-min Demo", "Onboarding Call") for a user or organization.
• Mark Invitee No-Show: Mark or unmark an invitee as a no-show for a scheduled event.
• List Routing Forms: List routing forms and optionally their submissions for an organization.
• List Organization Members: List all members of a Calendly organization.
• List Event Invitees: List invitees for a scheduled event.
• Create Event Invitee: Book a Calendly meeting by creating an invitee for an event type at an available start time.

• Get Event Invitee: Retrieve detailed invitee information for a scheduled event, including contact details, answers, no-show status, and cancellation/reschedule links.

• Type @ and pick the plugin. The selection applies to that message only, so @mention it again when a follow-up needs fresh Calendly data.
• For write actions, ChatGPT may ask you to confirm first, depending on the app permissions and the action.
• Once published for a workspace, ChatGPT keeps a snapshot of the tool list. When your team adds Calendly tools in Metorial, an admin refreshes the actions in Workspace settings before they appear.
• You can use several apps in one prompt, for example read Calendly data and then create a ticket in another app.

Add custom MCP server is missing

Workspace policy controls it. On Enterprise and Edu, an admin grants the permission to create plugins with MCPs; ask them to enable it for you.

The plugin exists but no tools appear

Creating the plugin is not enough: install it from your plugins, then start a new conversation so ChatGPT loads its tools.

ChatGPT answers without using the tools

Pick the plugin with @ in the composer and name the action you want, for example "use Metorial to look up the latest ticket".
