Google Calendar - Prisme.ai

The Google Calendar app provides read/write access to a user’s Google Calendar through the Calendar API v3. It can be used either as a Builder app (automations call Calendar instructions directly) or as a remote MCP server consumed by an AI agent. Each tenant configures its own Google OAuth Application; end-users sign in with their own Google account and tokens are stored per (user × tenant). The connector exposes 32 underlying operations, grouped into 7 entity tools covering events, calendars, the user’s calendar list, sharing rules (ACL), user settings, the color palette and free/busy queries.

Events

Create, search, update, move, import and expand recurring events; quick-add from natural language; attach Google Meet conferences

Calendars & Sharing

Manage secondary calendars, the user’s calendar list, and ACL rules to share calendars with users, groups or domains

Availability & Settings

Query free/busy across multiple calendars and read user settings, time zones and the color palette

Prerequisites

A Google account with access to the calendar you want to expose. For Google Workspace, the workspace admin may need to allow third-party OAuth apps.
A Google Cloud project with the Google Calendar API enabled at console.cloud.google.com/apis/library/calendar-json.googleapis.com.
A Google OAuth 2.0 Client of type Web application, created at console.cloud.google.com/apis/credentials. The Authorized redirect URIs must contain the value shown in the OAuth Callback URL field of the installed app instance (auto-populated on install — copy it back into the Google Cloud Console after installation).
An OAuth consent screen configured in the Google Cloud project. While the app is in Testing state, add the end-user’s email to Test users. The full Calendar scope (https://www.googleapis.com/auth/calendar) is classed sensitive by Google and goes through Google’s verification process when the consent screen moves to Production.
Base URL (default: https://www.googleapis.com/calendar/v3)

Usage as MCP

Installation

Go to Apps in your workspace
Search for Google Calendar and install it
Open the app instance configuration and fill in the required fields

Configuration

Field	Description
Google Calendar API Base URL	Base URL of the Calendar API (default `https://www.googleapis.com/calendar/v3`)
API Token (fallback)	Optional static OAuth access token used as a shared fallback for all users of this tenant. Stored as a workspace secret. Most deployments leave this empty and rely on per-user OAuth instead.
OAuth2 Client ID	Google OAuth Application Client ID. Create an OAuth client of type Web application in the Google Cloud Console
OAuth2 Client Secret	Google OAuth Client Secret, stored as a workspace secret
OAuth Callback URL	Auto-populated on install — paste this value into the Authorized redirect URIs list of your Google OAuth client
OAuth Authorize URL	Default `https://accounts.google.com/o/oauth2/v2/auth`
OAuth Token URL	Default `https://oauth2.googleapis.com/token`
OAuth Revoke URL	Default `https://oauth2.googleapis.com/revoke`
OAuth Scopes	Space-separated Google API scopes. Default `https://www.googleapis.com/auth/calendar` (full read/write). Other common values: `calendar.events`, `calendar.readonly`, `calendar.settings.readonly`
Refresh Token TTL (seconds)	Default 15552000 (180 days, Google’s max)
Max Tool Payload (KB)	Threshold above which MCP responses are auto-compacted into a summary + recovery hints to avoid overflowing the LLM context. Default 50. Raise it (for example 200) when targeting LLMs with 1M-token windows
MCP Endpoint	Auto-populated on install — URL of the MCP endpoint for this instance
MCP API Key	Auto-populated on install — signed key used in the `mcp-api-key` header. Do not modify

MCP Endpoint, MCP API Key and OAuth Callback URL are generated automatically by the onInstall flow. The OAuth credentials below (OAuth2 Client ID, OAuth2 Client Secret) must be filled in manually after creating the OAuth client in the Google Cloud Console.

Authorize end-users

Once the app instance is configured, each end-user authorizes their own Google account through a browser-based consent screen:

Trigger the connect flow

From an MCP client (Agent Creator capability or any tool client), call any data tool. If no OAuth session exists for the current user × tenant, the MCP server returns a connector_auth_required payload with a connect_url. Alternatively, call the connect tool explicitly to receive the same payload.

Open the connect URL

Open the returned URL in a browser tab where the user is already authenticated to Prisme.ai. The platform redirects to the Google OAuth consent screen.

Grant access

The user reviews the requested scopes (default https://www.googleapis.com/auth/calendar) and clicks Allow. Google redirects back to the platform’s oauthCallback webhook.

Confirmation

The user sees a Connection complete page and can close the tab. The platform has stored an access token plus refresh token as user-scoped secrets — both are tenant-prefixed so they do not leak across app instances.

Each user’s OAuth tokens are scoped per (user × tenant). A user who has authorized in tenant A does not gain access in tenant B — they must run the connect flow again per app instance. Refresh tokens are rotated by Google on each refresh and live up to 180 days when idle.

Available Instructions

Every instruction resolves credentials from the workspace configuration. Most operations default to calendarId: primary — pass an explicit calendar ID or email to operate on another calendar the user has access to. List operations accept maxResults and pageToken for pagination, plus syncToken for incremental sync.

The Google Calendar app ships with a built-in MCP server. Each app instance gets its own signed mcp-api-key that encodes the workspace ID and a credentials lookup URL — the Google Calendar API token itself is never passed through headers and is resolved server-side from the app configuration plus the per-user OAuth session.

Plug into an Agent Creator capability

Agents consume MCP servers directly through Agent Creator capabilities. This is the preferred way to expose Google Calendar to an agent.

Create or open a workspace

From the Prisme.ai console, create a new workspace (or open the one that will host the connector).

Install the Google Calendar app

Open the workspace Imports panel, search for Google Calendar and install it.

Configure the credentials

Open the freshly installed app instance settings and fill in the OAuth Client ID and Client Secret (see the Usage as App tab for the field-by-field reference).

Copy the MCP endpoint and API key

Still on the app instance configuration page, copy the values of MCP Endpoint and MCP API Key — both are generated automatically on install.

Open Agent Creator

Switch to Agent Creator and open the agent you want to extend.

Add a capability

Add a new capability to the agent:

If a dedicated Google Calendar capability exists — select it and paste the MCP API Key into the mcp-api-key field. The server URL is already wired.
Otherwise — select the generic custom_mcp capability, paste the MCP Endpoint into the Server URL field, then open the Headers field and add an mcp-api-key entry whose value is the MCP API Key copied earlier:
```
{
  "mcp-api-key": "your-mcp-api-key"
}
```

Save

The agent now has access to every Google Calendar tool exposed by the MCP server.

Brief the agent in its system prompt

Wiring the capability is not enough — the agent also needs to know the MCP exists and when to reach for it. Add a short paragraph to the agent’s system prompt. Copy-pasteable starter:

You have access to the Google Calendar MCP server. Use it whenever the user asks about meetings, availability, scheduling or calendar sharing — listing upcoming events, creating or updating events, querying free/busy, managing calendars or sharing rules. The first call may return a connect_url asking the user to authorize their Google account; relay it as-is. Always confirm with the user before any destructive action (delete event, delete calendar, revoke ACL).

Refine the trigger keywords (resource names, business domains, typical user phrasings) so the agent reliably picks up the right intent in your context.

Legacy MCP Install (Advanced > Tools)

Use this flow to plug the Google Calendar MCP into an AI Knowledge agent that does not yet support the native MCP picker.

Install the Google Calendar app

Install and configure the app in the same workspace as your agent (see the Usage as App tab). Once configured, mcpEndpoint and mcpApiKey are auto-populated.

Copy the MCP credentials

Open the app instance config and copy the values of MCP Endpoint and MCP API Key.

Open your AI Knowledge project

Navigate to Advanced > Tools.

Add an MCP tool

Click Add and select the MCP tab.

Fill in the endpoint

Paste the MCP Endpoint URL copied from the app instance.

Add the auth header

In the Headers field, add the signed API key:

{
  "mcp-api-key": "your-mcp-api-key"
}

Save

The agent can now list and call Google Calendar tools through the MCP endpoint.

The signed mcp-api-key encodes the workspace ID and the getConfig webhook URL. The MCP server validates the signature using the central app secret and transparently fetches the OAuth client credentials and base URL from the installed app, then resolves the calling user’s stored Google access token. Credentials are cached per tenant for 10 minutes; user OAuth tokens are refreshed on demand.

Output Formats

Every tool accepts an outputFormat parameter that controls the MCP response shape:

verbose (default) — human-readable text for LLM consumption
structured — machine-readable JSON in structuredContent
both — both text and structured content

Available Tools

The MCP server exposes 7 entity-level tools (each with an action argument to select the operation) plus the 2 generic OAuth tools. Below is the operation matrix.

Error Handling

HTTP Status	Meaning	Typical Cause
`400`	Bad Request	Malformed RFC3339 timestamp, missing required field, conflicting parameters

`403`	Forbidden	Calendar API disabled in the Google Cloud project, scope insufficient for the operation, sharing restricted by Workspace admin
`404`	Not Found	Event/calendar/ACL rule does not exist or the user lost access
`409`	Conflict	Optimistic concurrency failure on update / patch (etag mismatch)
`410`	Gone	`syncToken` has expired — perform a full sync (omit `syncToken`) and refresh the token
`429`	Rate Limited	Per-user or per-project quota exhausted. Back off and retry
`500` / `503`	Server Error	Transient Google Calendar API error. Retry with exponential backoff

Common Issues

“Not configured” — The app instance has no OAuth Client ID/Secret. Create an OAuth client in the Google Cloud Console and paste the credentials into the app configuration. “Invalid API key” (MCP) — The mcp-api-key header does not match the central app secret. Reinstall the app instance to regenerate a signed key. “Credentials lookup failed” — The MCP endpoint could not reach the getConfig webhook of the installed app. Verify that the app instance is still installed in the expected workspace. connector_auth_required — The calling user has no Google OAuth session yet for this tenant. The response payload includes a connect_url; relay it to the user so they can authorize their Google account. redirect_uri_mismatch during the OAuth dance — The value of OAuth Callback URL in the app config has not been added to the Authorized redirect URIs of the Google OAuth client. Copy it back into the Google Cloud Console and retry. Token has been expired or revoked (401 after a previously working setup) — The refresh token has been invalidated (user revoked access, password change, more than 180 days idle, or Google moved the OAuth app from Testing to Production). Ask the user to run the connect flow again.
