How to integrate Google Calendar using MCP
Browse Google calendars and events. This guide creates an MCP server from Arthur's Google Calendar template — tools preconfigured against https://www.googleapis.com/calendar/v3 — and finishes by sharing the server's MCP swagger documentation.
Steps
Open the Secrets vault and create a secret named
GOOGLE_CALENDAR_API_KEYholding your access token. Enable Google Calendar API in a Google Cloud project, complete OAuth 2.0 consent, and provide an access token with calendar.readonly (or the narrower calendarlist.readonly plus events.readonly scopes).


Go to the REST API Templates gallery and search for Google Calendar.


Click Use template on the Google Calendar card to open the server-creation dialog.


Review the server name and select
GOOGLE_CALENDAR_API_KEYin the credential field — the dialog only accepts vault secrets, and it lists every tool that will be created.


Click Create server. Arthur creates the server, applies the authentication, and generates all the tools.





Open the server's Tools tab to review the generated tools.

Open the server's Connect section and click Share the MCP swagger documentation — Arthur generates the public documentation link and QR code for this server.



Confirm it worked
The server appears with 3 preconfigured tool(s): list_calendars, list_events, get_event. The Connect section offers the MCP swagger documentation — a shareable page with setup instructions for any AI client.
Good to know
- List calendars available to a Google user, browse events within a time range, and retrieve one event by its Calendar identifier.
- This integration requires a credential (bearer). Get one at https://console.cloud.google.com/.
- Official API documentation: https://developers.google.com/workspace/calendar/api/v3/reference
- Editing a tool later never changes the template — templates are starting points, and the server is fully yours after creation.
