Google Workspace MCP Servers
Aembit supports the official Google Workspace MCP servers, which let AI Agent: A software workload that authenticates to systems, requests credentials, and accesses resources, either on behalf of a person or on its own. Aembit secures AI agents with the same identity-first model it uses for any workload. User-driven agents such as Claude Desktop also carry a blended identity that ties access to both the user and the agent.Learn more read Drive files, calendar events, and contacts through Model Context Protocol: A standard protocol for AI agent and server interactions that defines how AI assistants communicate with external tools and data sources.Learn more(opens in new tab) tools.
This page describes how to configure three Google Workspace MCP Server: A server that implements the Model Context Protocol to provide tools, resources, or data to AI agents and MCP clients.Learn more(opens in new tab): Google Drive, Calendar, and People. The Aembit MCP Identity Gateway: A component that brokers MCP traffic between MCP clients and target MCP servers, validating authorization and presenting Aembit-managed credentials on each request.Learn more brokers the connection. Each user authenticates with their own Google identity, and the Gateway injects their token into MCP requests.
Prerequisites
Section titled “Prerequisites”Before you begin, ensure you have the following:
- A Google Cloud project where you can enable APIs and create OAuth credentials
- A Google Workspace organization enrolled in Google’s Developer Preview Program (see Requirements and considerations)
- A configured Aembit MCP Identity Gateway
Requirements and considerations
Section titled “Requirements and considerations”Before you configure Google Workspace, review these requirements and behaviors specific to Google’s MCP servers.
- Enroll in Google’s Developer Preview Program. Google’s Workspace MCP servers are available only through the Developer Preview Program. Until your organization enrolls, Google returns permission errors for every tool call. Preview enrollment also expands the data Google collects on the vendor side. Review Google’s Preview terms before you enroll.
- Configure each service on its own. Drive, Calendar, and People each require their own GCP OAuth client, their own enabled API, and their own Aembit Credential Provider, Server Workload, and Access Policy.
- Google Chat isn’t available. The Gateway returns an “Internal error encountered” for every Google Chat tool, so this guide doesn’t cover Chat.
- Gmail isn’t available. This guide doesn’t cover Gmail.
Service settings
Section titled “Service settings”Each service uses the same configuration flow but different values. Use the values for the service you’re
configuring in the following steps.
These scopes grant read-only access. Substitute the read/write variant (for example,
https://www.googleapis.com/auth/drive instead of drive.readonly) if your agents need to modify data.
| Setting | Value |
|---|---|
| API to enable | drive.googleapis.com |
| OAuth scope | https://www.googleapis.com/auth/drive.readonly |
| MCP Server URL | https://drivemcp.googleapis.com/mcp/v1 |
| Server Workload host | drivemcp.googleapis.com |
| URL Path | /mcp/v1 |
| Setting | Value |
|---|---|
| API to enable | calendar-json.googleapis.com |
| OAuth scope | https://www.googleapis.com/auth/calendar.readonly |
| MCP Server URL | https://calendarmcp.googleapis.com/mcp/v1 |
| Server Workload host | calendarmcp.googleapis.com |
| URL Path | /mcp/v1 |
| Setting | Value |
|---|---|
| API to enable | people.googleapis.com |
| OAuth scope | https://www.googleapis.com/auth/contacts.readonly https://www.googleapis.com/auth/directory.readonly https://www.googleapis.com/auth/userinfo.profile |
| MCP Server URL | https://people.googleapis.com/mcp/v1 |
| Server Workload host | people.googleapis.com |
| URL Path | /mcp/v1 |
Set up your Google Cloud Platform project
Section titled “Set up your Google Cloud Platform project”Repeat this section for each Google Workspace service you want to enable. Each service needs its own enabled API and its own OAuth client.
-
In the Google Cloud console, select the project you want to use.
-
Enable the API for your service (see Service settings). If a later tool call reports that an API “has not been used or is disabled,” enable the API named in that error too.
-
Go to the Credentials page, click Create Credentials, then select OAuth client ID. If your project has no consent screen, configure one first: choose a User type, enter the app details, then add your service’s OAuth scope.
-
For Application type, select Web application, enter a name, then click Create. Leave Authorized redirect URIs empty for now. You add the Aembit Callback URL after you create the Credential Provider.
-
Copy the Client ID and Client secret, and store them for the next section.
Configure the Credential Provider
Section titled “Configure the Credential Provider”Create an MCP User-Based Access Token Credential Provider: Credential Providers obtain the specific access credentials—such as API keys, OAuth tokens, or temporary cloud credentials—that Client Workloads need to authenticate to Server Workloads.Learn more in Aembit for the service.
-
Log into your Aembit Tenant.
-
Go to Credential Providers in the left sidebar and click + New.
-
Configure the following fields:
Field Value Name A user-friendly name Credential Type MCP User-Based Access Token MCP Server URL Your service’s MCP Server URL (see Service settings) Client ID The Client ID you copied from Google Cloud Client Secret The Client Secret you copied from Google Cloud Scopes Your service’s OAuth scope (see Service settings) PKCE Required On For MCP Server URL, click Discover to populate the Authorization URL and Token URL.
-
Click Save.
-
Copy the read-only Callback URL from the Credential Provider.
Finish configuring the OAuth client
Section titled “Finish configuring the OAuth client”Return to the OAuth client in the Google Cloud console.
-
Open the Web application OAuth client you created for this service.
-
Under Authorized redirect URIs, click Add URI, paste the Aembit Callback URL, then click Save.
Authorize the Credential Provider
Section titled “Authorize the Credential Provider”-
Return to the Credential Provider in Aembit and click Authorize.
-
Choose your Google Account and approve access. The Credential Provider status changes to Ready when the flow completes.
Create the Server Workload
Section titled “Create the Server Workload”-
Go to Server Workloads in the left sidebar and click + New.
-
Configure the following fields:
Field Value Name A user-friendly name Host Your service’s Server Workload host (see Service settings) Application Protocol MCP Port 443 with TLS URL Path Your service’s URL Path (see Service settings) Authentication method HTTP Authentication Authentication scheme Bearer -
Click Save.
Create an Access Policy
Section titled “Create an Access Policy”Create an Access Policy: Access Policies define, enforce, and audit access between Client and Server Workloads by cryptographically verifying workload identity and contextual factors rather than relying on static secrets.Learn more linking your Client Workload: Client Workloads represent software applications, scripts, or automated processes that initiate access requests to Server Workloads, operating autonomously without direct user interaction.Learn more (the AI agent), the service’s MCP User-Based Access Token Credential Provider, and the service’s Server Workload. See Access Policies for details.
Verify
Section titled “Verify”After a user authorizes access, the Aembit AI Access Authorized page lists each configured Google Workspace MCP Server as Ready. The AI agent can then call the corresponding MCP tools (such as listing Drive files or calendar events) through the Gateway.
